A glass core device with a wiring pattern on a first surface of a glass core and a wiring pattern on a second surface thereof being electrically connected via a wiring pattern embedded in TGVs formed in the glass core. In a state of being cut out by dicing, each glass core has a second surface and side faces which are continuously covered with an outer protective layer.

Glass core device and method of producing the same

A metal photoetching product comprising at least one large cavity of minor axis WS, major axis WL and depth Din a surface of the product, wherein one or more cavities are included inside at least one of the at least one large cavity, and a smallest hole among the cavities has minor axis of WS, major axis WL, and depth D; and the product satisfies the following dimensions, D+D=plate thickness D, 0.02 mm&#x2266;D&#x2266;2 mm, 0.4&#xd7;D&#x3c;WS&#x3c;D, and 0.2&#xd7;D&#x3c;WS&#x3c;0.8&#xd7;D.

Metal photoetching product and production method thereof

A metal photoetching product comprising at least one large cavity of minor axis WS, major axis WL and depth Din a surface of the product, wherein one or more cavities are included inside at least one of the at least one large cavity, and a smallest hole among the cavities has minor axis of WS, major axis WL, and depth D; and the product satisfies the following dimensions, DDplate thickness D, 0.02 mm&#x2266;D&#x2266;2 mm, 0.4&#xd7;D&#x3c;WS&#x3c;D, and 0.2&#xd7;D&#x3c;WS&#x3c;0.8&#xd7;D.

Abnormality of a comparator is to be detected while it is assembled in a control apparatus. An output OUT of a comparatoris connected to a first analog data input portin addition to an input portof a microcomputer. A pin Pas a signal input terminal of the comparator is connected to a second output portcapable of outputting an H or L microcomputer signal MO of the microcomputer and also to a second analog data input port. An abnormality judgment portionof the microcomputer can detect abnormality due to failure of the comparator itself and failure of the peripheral devices on the basis of the output of the comparator during a normal operation, the comparator output when the microcomputer signal is outputted, and the comparator outputs before and after the output and stop of the microcomputer signal.

Abnormality detection apparatus of comparator

Steering angle detecting apparatus of a steering is constituted to dispense with reexecution of initial setting by a simple angle sensor. CPU is connected with an MR sensor attached to a rotating member rotated in cooperation with a steering shaft for detecting a periodic angular position and CPU subjects data from the MR sensor to an operation processing by using a reference position stored to an involatile data storing portion to thereby calculate an absolute steering angle including a number of an order of turns. When an ignition is made OFF, there is constituted a low current consumption mode for carrying out calculation by intermittent operation and power source to the MR sensor is made OFF by a sensor switch. The reference position is stored to the involatile data storing portion and therefore, even after detaching and attaching a battery, initial setting is dispensed with.

Rotational angle measuring apparatus

A multilayered conductive film has a silver-based layer formed of a silver-based metallic material. A first transparent oxide layer is provided on one surface of the silver-based layer, and a second transparent oxide layer is provided on the other surface of the silver-based layer. The first and second transparent oxide layers are independently formed of a compound oxide material of indium oxide with at least one secondary metal oxide whose metallic element has substantially no solid solubility in silver.
