Title: Wafer pre-alignment system
Inventor: OTA KAZUYA
IPC: H01L21/68
Filed: 1986-10-24
Abstract: PURPOSE:To make it possible to perform alignment highly accurately, by detecting the position of an orientation flat with light spots, which are projected from exposing-position detectors, and performing prealignment without providing a pre-alignment device on a stage. CONSTITUTION:A wafer 7 is mounted on a stage 8. At this time, parallelism of the orientation flat of the wafer with respect to the stage 8 is sometimes misaligned in two deliveries, when the wafer is transferred to a transfer arm from a pre-alignment device, which is being conveyed, and when the wafer is mounted on the stage 8 from the transfer arm. Therefore, the wafer 7 mounted on the stage 8 should be aligned again. The orientation flat F is scanned in the direction of (y) with light spots LA, which are projected from exposing-position detectors 21-31 through projection lenses. The optical data emitted from two points, which are separated by a specified amount in the direction of (x), are detected. The positional difference of the two points in the direction (y) is obtained. On the bases of the positional difference and the separating distance in the direction (x), the rotated deflection angle of the flat F in the direction (x) is obtained.

Title: Fuel injection device for engine
Inventor: RIKITAKE TOMOTSUGU
IPC: F02D41/34
Filed: 1990-09-20
Abstract: PURPOSE:To improve combustibility by injecting fuel through a fuel injection valve on the downstream side in a low and a high rotation region and injecting fuel through a fuel injection valve on the upper stream side in a middle rotation region. CONSTITUTION:Since the velocity of flow of intake air in a suction passage 4 is low in a low rotation region and a user does not expect too much of promotion of vaporization and atomization of fuel in intake air, response of an output change to a change in a fuel injection amount is improved through injection of fuel through a fuel injection valve 19 on the downstream side. Since turbulence of intake air is high in a middle rotation region and vaporization and atomization of fuel in intake air are promoted, fuel is injected through a fuel injection valve 17 on the upper stream side, and combustibility of fuel-air mixture is improved. Since the velocity of flow of intake air is extremely increased in a high rotation region, fuel is injected through a fuel injection valve 19 on the downstream side, and collision and adhesion of fuel with and on the inner peripheral surface of the suction passage 4 are reduced. This constitution improves combustibility.

Title: Wireless communication device
Inventor: MURAMATSU TAKESHI
IPC: H04Q9/00
Filed: 1988-10-07
Abstract: PURPOSE:To save the power of a receiving part by changing the combination of the power supply time and the power stoppage time of the power to be supplied to the receiving part to another combination by a power control part when a switching instruction signal is received from a master station or an input is inputted to the selector switch of its own station. CONSTITUTION:A received electromagnetic wave is demodulated by the receiving part 1, and is inputted to a communication control part 4 as a reception signal. The power control part 5 controls the power of the receiving part 1 and a transmitting part 2 in conformity with instructions from the communication control part 4. The power to the transmitting part 2 is supplied only at the time of transmission. The power to the receiving part 1 is supplied intermittently in order of supply and supply stoppage at the time to wait for reception, and when the reception signal is detected once, it is supplied continuously till the finish of the signal. When the switching instruction signal from the master station is transmitted while the power is supplied intermittently at the combination of the power stoppage time T1 and the power supply time T2, the combination is changed into the combination of the power stoppage time T3 and the power supply time T2. Thus, a synchronizing signal becomes longer and the response of communication is delayed, but the power saving of a circuit current at the time to wait for the reception can be realized.
