Title: Game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 1999-10-04
Abstract: PROBLEM TO BE SOLVED: To prevent a player from being put at a disadvantage by the occurrence of power-off. SOLUTION: A voltage drop signal from a first power monitoring circuit mounted on a power board is inputted to an input port 570. The first power monitoring circuit is a circuit for detecting the drop of supply voltage by monitoring +30V supply voltage out of various DC power supplies used for a game machine. In a second power monitoring circuit 903, a power monitoring IC 904 monitors +30V supply voltage equal to the supply voltage monitored by the first power monitoring circuit, and generates a voltage drop signal when the voltage value is the specified value or less. The voltage detected by the first power monitoring circuit mounted on the power board is made +16V, and the voltage detected by the second power monitoring circuit 903 is made +8V.  A CPU 56 executes power-off processing in response to the voltage drop signal from the first power monitoring circuit and is reset by the voltage drop signal from the second power monitoring circuit 903.

Title: Wafer carrying apparatus
Inventor: HAYASHI YUJI
IPC: H01L21/68
Filed: 1987-11-09
Abstract: PURPOSE:To make it possible to carry a wafer in accordance with the tilt with respect to a horizontal direction of the wafer, by providing a pair of crosswise independent rotation position correcting part which rotatably supports a pulley on a pulley supporting plate having a rolling friction coefficient smaller than that of the pulley internally touching a belt at a wafer carrying part. CONSTITUTION:When the position of a wafer 5a is shifted from a set position shown by a broken line, a second friction coefficient of pulley supporting plates 13a and 13b of rotation position correcting parts 8a and 8b and a shaft 14 is set smaller than a first friction coefficient of pulleys 11a, 11b and shafts 12a, 12b, so that the pulley supporting plates 13a and 13b rotate in a rotation direction of an arrow B by a rotation force to a direction of an arrow A of belts 7a and 7b. Therefore, the rotation supporting position correcting parts 8a and 8b rotate in the direction of the arrow B and the upper surface of the belts 7a and 7b touches the bottom surface of the wafer 5a and then the wafer 5a is carried. In addition, since the rotation position correcting parts 8a and 8b can rotate individually, position can be corrected right and left separately and it is possible to correspond with the tilt of the wafer.

Abstract: PURPOSE:To enhance the tolerance for position errors with respect to the lightguide of semiconductor laser and to decrease the difficulty in manufacturing of an optical pickup by providing a means for adjusting the intensity of the laser light emitted from the semiconductor laser. CONSTITUTION:The laser light which is directed toward a photodetector 21 with a beam splitter 20 is detected with the photodetector 21.

The voltage is compared with the reference voltage in a voltage comparing circuit 23. When the reference voltage and the converted voltage are different, the output of the circuit 23 acts in the suppressing direction for the voltage difference. The output voltage is converted into the current in a voltage/current converter circuit 24. The current is fed back to a semiconductor laser 3. In this constitution, the laser light having the constant intensity is obtained regardless of the coupling state at the edge of a lightguide 2.

Filed: 1986-11-29
Abstract: PURPOSE:To enhance sensitivity and to obtain a sharp image by alternately laminating microcrystalline silicon thin films and semiconductor thin films composed essentially of B and N to form at least one part of a barrier layer and specifying the thickness of each thin film. CONSTITUTION:The barrier layer 2 has superlattice structure obtained by alternately laminating the microcrystalline silicon (muC-Si), and the semiconductor thin films composed essentially of B and N, and muC-Si may be hydrogenated, and each of the thin films has the film thickness of 3-20nm. The surface of a photosensitive body is positively charged by forming the barrier layer 2 of a p-type, and preventing electrons for neutrifying surface charge from being injected into an electric charge generating layer, and on the contrary, the surface is negatively charged by forming the layer 2 of an n-type and preventing holes for neutralizing the surface charge from being injected into the charge generating layer. Since the carriers to be injected from the layer 2 become noises to the incident of light, said prevention of carrier injection permits sensitivity to be enhanced and a sharp image to be obtained.
