Title: Driver of air blower, etc., rotating speed detector of air blower, etc., motor, and air blower
Inventor: MOCHIDA NORIHITO
IPC: H02P23/07
Filed: 1994-05-06
Abstract: PURPOSE:To make stable control of a rotating speed of a motor by comparing the detected rotating speed of the induction motor with a set desired rotating speed and by determining a conduction ratio of a bidirectional conduction element so that there may be no difference between the detected rotating speed and the set one. CONSTITUTION:A rotating speed sensor 5 detects the rotating speed of an induction motor 1. A signal generator 6 generates a pulse signal which has a frequency corresponding to the rotating speed detected by the rotating speed sensor 5. An arithmetic means 7 calculates the optimum conduction ratio of a TRIAC (a bidirectional conduction element) 2 based on the pulse signal from the signal generator 6. A gate drive circuit 8 gives a gate signal to the TRIAC 2. In other words, the rotating speed of the induction motor 1 detected by the rotating speed sensor 5 and the set desired rotating speed are compared with each other and the conduction ratio of the TRIAC 2 can be so determined that there may be no difference between the two rotating speeds. By this method, a stable control of a rotating speed of the induction motor 1 is available.

Title: Electric flashing device
Inventor: UCHIYAMA SHIGEYUKI
IPC: G03B7/16
Filed: 1994-05-09
Abstract: PURPOSE:To lengthen a photographing feasible distance without making a main capacitor large in slit exposure by pulsed light emission. CONSTITUTION:When the emitted light intensity of a light emitting part is detected by a detection means and the detected value attains a reference value, the light emission by the light emitting part is temporarily stopped, and the light emitting part emits the light again according to a light emission start signal outputted after that. By repeating such operation, the pulsed light emission is performed. At such a time, the reference value is changed with the lapse of time and the emitted light intensity becomes higher with approaching nearer to the center part of a picture, so that a subject located on a far side is irradiated with more sufficient light quantity than in the conventional manner and the photographing feasible distance is lengthened in the pulsed flash photographing at high shutter speed where the slit exposure is performed such as daylight synchro photographing.

Title: Semiconductor integrated circuit device
Inventor: SUMI KATSUAKI
IPC: H03M1/08
Filed: 1986-04-22
Abstract: PURPOSE:To prevent transistors(TRs) constituting a constant current circuit from saturation and to attain normal A/D conversion by providing the titled device with an input clip TR for preventing an inputted analog signal from voltage drop less than a fixed voltage. CONSTITUTION:When an analog signal including pulse-like noise is inputted, the input clip TR 28 is driven and the voltage of a terminal 2 to which the analog signal is inputted is prevented from voltage drop less than the voltage of a base voltage impressing terminal 29 and the terminal 2 is driven so that a waveform shown by a solid line is inputted. Thereby, the TR 28 is turned off in an input level within a conversion range and the potential of the terminal 29 of the TR 28 is selected so that the TR 28 is driven when the voltage of the analog signal is dropped slightly less than a voltage VL. Even if the analog signal including the pulse-like noise is inputted, a TR 11 and a TR 17 for a current switch constituting the constant current circuit are not saturated and the A/D converter is normally driven.

Title: 1/4 inch cartridge magnetic tape
Inventor: NATORI TOSHIHIRO
IPC: G11B15/06
Filed: 1986-04-24
Abstract: PURPOSE:To expand a data recording area by making a BOT (Beginning of Tape) hole and an EOT (End of Tape) hole into the shape which is extended in the travelling direction only to the length to be able to execute the secure detection and providing them at the prescribed position of the starting edge and the terminal side of a magnetic tape. CONSTITUTION:Since a BOT hole 1 and an EOT hole 2 are formed to the oval shape extended to the prescribed length only in the travelling direction respectively, the time when the light emitting element of the detecting means of the BOT/EOT holes comes to be long, the secure detection equal to three BOT/EOT holes provided at the conventional 18-inch interval can be executed by one hole. For example, by making the BOT hole 1 and the EOT hole 2 into the oval shape at the 1/4 inch cartridge magnetic tape of the figure, the detection of the starting edge and the terminal area of the tape can be executed without fail with one BOT/EOT hole. Thus, the length of the tape necessary to provide the BOT hole 1 and the EOT hole 2 is sufficient by 1/3 of the conventional length, and therefore, a larger data recording area by the decreased length can be obtained.

Abstract: PROBLEM TO BE SOLVED: To prevent the windy noise by forming cross sectional shape of a handrail member into a nearly elliptic shape having a longitudinal axis, and arranging the handrail members in parallel with each other so that the longitudinal axis of each handrail member is inclined in opposite directions each other. SOLUTION: A handrail 1 is provided on the floor 6 while arranging plural bar-like handrail member 5 having a length L in parallel with each other with a space P between a right and a left supports 2, 2 and between an upper frame 3 and a lower frame 4.

The handrail members 5 having the elliptic cross section are arranged with a constant pitch P while being inclined in opposite directions each other so that the adjacent handrail members 5 form a-shape.  Since the cross section of each handrail member is formed into the elliptic shape without having corners and the handrail members are arranged while being inclined in the opposite directions each other so that the cross section of the adjacent handrail members is formed into the-shape, windy noise can be effectively prevented by the simple structure.
