An electric vehicle ( ) including a rechargeable secondary battery ( ), an electric motor ( ) for driving a running section such as wheels and the like and a controller ( ) for conducting control to drive the electric motor by electric power from the secondary battery ( ) is provided with a nonvolatile memory ( ) for storing a password, a display and operation unit ( ) for inputting a password, means (the controller ( ) may also serve) for bringing the vehicle into a state capable of being driven only when the password inputted through the display and operation unit ( ) matches the password stored in the memory ( ).

Electric vehicle

An electric device ( ) in which a driver ( ) drives an electric motor ( ) by use of electric power supplied from a power supply ( ) having a rechargeable secondary battery, and a controller ( ) monitors, manages, and controls the driver and the whole device, is provided with a portable device power supply ( ) to which a portable device ( ) is connectable and which supplies electric power supplied from the power supply ( ) to the connected portable device ( ) and a portable device interface means ( ) for communicating information with the connected portable device ( ).

Electric machine, electric machine system

An electric device comprises a plurality of detachable battery units ( ), each consisting of a set of storage battery packs ( B, B, B) and memories ( ) storing information about the charge and discharge states of the battery packs. Connectors are provided to connect and disconnect an electric device ( ) electrically incident to each battery unit being attached or detached. The device includes a driver ( ) for driving a load, a charger ( ) for charging the storage battery packs ( B, B, B) by referring to the information stored in the memories ( ) of the respective mounted battery units ( ), and a controller ( ) for controlling the electric power supplied from the individual battery units ( ) to the driver ( ) by referring to the above-mentioned information.

A radio communication system is used with an electronic appliance such as a wristwatch. The radio communication system includes a single transmitter unit including a first reference clock pulse generator which transmits paging data together with message data. A plurality of receiver units each have a second reference clock pulse generator which is built in the appliance, to decode the paging and message data uniquely characterizing that receiver unit with the help of a second reference clock pulse which has been synchronized with a first reference clock pulse. The paged operator is warned and the message is displayed.

A dot interpolation control system according to the invention includes a dot pattern memory storing character pattern data having a predetermined dot matrix format. Dot data of four adjacent dots is obtained from the dot pattern memory. X and Y off-set values of a position in an area surrounded by the four dots are stored using one of the dot data of four adjacent dots as a reference point. Dot interpolated value data in the area surrounded by the four dots is stored in an interpolating table ROM in accordance with all combination of ON- and OFF-states of the dot data of four adjacent dots. The dot data of four adjacent dots and the X and Y off-set values are supplied to the interpolating table ROM. A dot interpolated value at a coordinate point indicated by the off-set values is generated in correspondence with ON- and OFF-states of the four adjacent dots.

Dot interpolation control system

An electronic musical instrument for reading out and performing musical tone data previously stored in a memory is disclosed. In the musical instrument, pitch data of a musical piece or pieces are previously stored in the memory. Desired pitch data stored are read out by operating a corresponding key arranged on a keyboard. A tone generator forms a musical tone signal on the basis of the pitch data for sounding the musical tone. When the keyboard is functionally divided into two groups, the musical tone for melody and/or accompaniment of the musical piece may be read out through the operation of the functionally divided keyboard.

Electronic musical instrument for reading out and performing musical

Predetermined performance keys in a group for a low octave section are used as read-out keys for reading out accompaniment memorized in a first memory, and the other keys in the keyboard are used as read-out keys for reading out melody memorized in a second memory. The read-out accompaniment and melody contents are reproduced with a first tone color designated by a first tone color designation switch given to the accompaniment and a second tone color designated by a second tone color designation switch given to the melody.

Electronic musical instrument with means for generating accompaniment

A sluice valve arrangement is adapted to make an air-tight partition or communication between a vacuum treatment chamber and the atmosphere or a pre-chamber. This arrangement includes a valve seat member comprising a cylindrical or spherical member having therein an opening, a pair of guide rails attached to the inner circumference of the seat member, a valve member movably supported on the guide rails, and means for air-tight engagement of the valve member and the valve seat portion of the seat member. The valve member has a curvature equal to that of the cylindrical or spherical member, and the engagement means comprises a plurality of bellows expandable by a compressed gas or air.

Sluice valve arrangement

Bar codes representing sound information are printed on a marginal portion of a score. Prior to the performance, these bar codes are read out by a bar code reader, whereby chord data represented by these bar codes are successively stored in a memory provided in the body of a musical instrument. At the time of the performance, accompaniment sound corresponding to the stored chord data is automatically added to the melody performed by the player.

A vacuum furnace for heat treatment comprises a heating furnace proper, pre-exhaust chambers, one adapted to feed a workpiece into the furnace proper therefrom and the other adapted to discharge the workpiece out of the oven proper thereinto, vacuum valves for partitioning between the oven proper and the respective pre-exhaust chambers, and a line assembly for deliver of the workpiece from the feed chamber into the discharge chamber through the furnace proper. A heating chamber forming part of the furnace proper is positioned on the upper part above the deliver line assembly, and an externally operable elevating means is disposed in the furnace proper. The work pieces carried by the delivery line assembly, and lifted to the heating chamber where it is heated.

Predetermined keys in a keyboard are used as reading keys for specifying the reading of note codes memorized in a memory section under the control of a function changing switch. Sounds corresponding to the note codes memorized in the memory section are delivered from a loudspeaker with a plurality of different volume levels set in the order of arrangement of the keys set as the reading specification keys.
