Title: Semiconductor device and manufacture thereof
Inventor: EMA YASUSHI
IPC: H01L21/8242
Filed: 1990-07-09
Abstract: PURPOSE:To increase storage capacitance under the condition that the level difference between a memory call and the peripheral area is reduced by ruggedly forming the side face of the storage electrode of a capacitor which constitutes a stacked capacitor type memory cell along with the wave-shaped side of the top plane. CONSTITUTION:Since the side faces of a stacked capacitor 11 are formed in a wave shape along the top side, the area of the side face becomes larger than that of the conventional structure whose top side is straight. Therefore, when the area and the height of the top face of a storage electrode 14 is the same as the conventional ones, the whole surface area becomes larger than the conventional device, the area opposing an opposed electrode 15 formed on the top face of the storage capacitance 14 is increased and the storage capacitance is increased. The rate of the side face occupation in the whole surface area is increased in response to the microminiaturizing a DRAM 10 and the effect of increasing the side face area is increased.

Filed: 1980-12-23
Abstract: PURPOSE:To detect travelling speed without the influence of distane, car height, from optical systems in an optical car speed detector by setting up appropriately the optical pathes of reflected rays from 3 detecting points. CONSTITUTION:A camera 30 incorporates 2 optical systems which are provided with lenses 31 and 32 respectively. The camera 30 is directed to a detecting surface P. The lens 31 includes the 1st and 3rd detecting points P1, P3 which are separated by L2 to each other within its field. The lens 32 detects the 2nd detecting point P2 which is positioned between these detecting points P1 and P2. Respective detecting points P1-P3 are correspondingly provided with photodetectors J1-J3, which detect reflected light when a car with speed V passes through P. If the required time for the distance between P1 and P2 and P2 and P3 are t1 and t2 respectively, speed V=d2/(T2-T1)[where, T1=t1(d1+d2)/ (a1+a2) and T2=t2d1/a2].

Title: Original detecting device
Inventor: MATSUO JIYUNKOU
IPC: G03G15/04
Filed: 1990-07-10
Abstract: PURPOSE:To restrain the influence of a noise and to prevent S/N from being lowered by amplifying an output signal from a light receiving device by a pre-amplifier so that it may be transmitted to a processing substrate. CONSTITUTION:The DC component of the output signal from the light receiving device 12 is removed by an AC coupling circuit 13 first, and the influence caused by disturbance light such as sunlight is eliminated. Then, the signal is amplified by the pre-amplifier 14 and transmitted to a harness 7. The output signal transmitted to the processing substrate 6 is adjusted in terms of level by a variable amplifier 19 and inputted in the analog input ports IN1 and IN2 of a microcomputer 16. Therefore, the lowering of the S/N is restrained because an original signal level is improved by the pre-amplifier 14 even though the noise interferes in the output signal from the device 12 on the harness 7.
