Provided is a concentration measurement device that can be miniaturized without using an optical fiber. The concentration measurement device including a measurement cell having a gas flow path and an optical path intersecting the gas flow path; a light source for emitting light inside the optical path, the light sourcebeing installed at one end of the optical path; a first photodetector for detecting a light emitted from the light source as a reference light, the first photodetector being installed at a side of the light source and rearward from a distal end of the light source in a light emitting direction along an optical axis of the light source; a second photodetector for detecting a light emitted from the light source for measuring light absorption, the second photodetector being installed at another end of the optical path.

Density measurement device

A concentration measuring device includes a measuring cell having a flow passage and a translucent window, a light source for emitting light to the measuring cell through the window, a reflective member for reflecting light propagating through the measuring cell to the window, a light detector for detecting the light exiting from the window, a calculation part for calculating the concentration of the fluid on the basis of a detection signal from the light detector, and an optical device for guiding the light from the light source to the window and guiding the light from the window to the light detector.

Concentration measuring device

The objective of this invention is to provide a game controller capable of using synchronizing signals to obtain accurate coordinates of an indicated position. Cables (,) and (,) transfer a video signal from a video output terminal of a main game machine unit and a control signal to a controller terminal. An HV separator (,) separates vertical and horizontal synchronizing signals from the video signal. Light from an aimed-at position is detected by a photosensor (,) provided within a gun (,), and a position computation section (,) obtains the coordinates of the aimed-at position, based on a detection pulse at that point and synchronizing signals from the HV separator (,). The cable (,) is connected to the cable (,) within a connector (,) so that a video signal and control signals are transferred by the cable (,). The video output terminal is connected to a video input terminal and a second game controller by using a connector (,) having male and female terminals (,) and (,). The HV separator (,) could be provided within the gun (,) or within the connector (,).

Game controller and information storage medium

It is an object of the present invention to provide a general purpose controller for a game machine by which a car game of a fishing game can be more enjoyed. A controller for a game machine comprises a jog dial,rotatably mounted on a controller main body,as a part of an input operating part, a data input system,driven according to and connected to the jog dial,to input data in accordance with the rotation of the jog dial and a counterforce urging means having a driving motor,or the like driving connected to the jog dial,for urging a counterforce opposite to the rotation thereof.
