Title: Elevator position indicating apparatus
Inventor: ISHIKAWA TORU
IPC: B66B3/02
Filed: 1989-08-29
Abstract: PURPOSE:To prevent an uncomfortable sound from being given, by providing a means for storing in memory a story from which an elevator is started at the last time, a means for isolating an elevator indicating device on the story from those on the other stories, and a receding indicating means which changes the positional indication concerning the above-mentioned story, precedingly among those the other stories. CONSTITUTION:At, for example, the second story, an elevator starts elevation after a door being closed, a contact in a door switch 22LS is opened, but a contact in a position detection switch 2PLS is closed until the elevator climbs by a predetermined distance. Accordingly, a relay B is still energized, and a contact B2 is also closed. Further, when a motor is rotated in a climbing direction after the elevator being started, a contact U is closed, and accordingly, a relay 2U is energized since a circuit consisting of P, B2, 2U and N is established. Thus, the contact 2U is opened so as to turn off a position indicating lamp 2L2 but turn on a position indicating lamp 3L3. That is, at a position indicating device on the second story, the position indicating lamp changes its indication from the second story to the third story when the elevator starts.

Title: Motor controller
Inventor: OMOTO SHUHEI
IPC: H02P7/292
Filed: 1990-08-22
Abstract: PURPOSE:To lengthen the service life of a motor by controlling the output of the motor with a pulsating current in approximately same intervals before and after a zero-cross point within a half period. CONSTITUTION:When power is turned ON, a motor rotates with a low speed to drive a rotary brush 24 with a low rotation. In other words, a low counter- electromotive force is induced in the motor 6 upon turn ON of power and a relatively high current flows therethrough and the inverted input voltage of an operational amplifier OP1 is increased by a current detecting resistor R1 thus producing a Low level. Since neither a capacitor C2 nor a capacitor C3 is charged, an AND circuit AN 3 outputs a Low level and no input is provided to one input terminal of an OR circuit OR 1. The other input terminal thereof is fed from a phase control signal output circuit 8 with a pulsating rectangular wave centered about a zero-cross point within a half period, and the motor 6 is fed with a voltage having maximum instantaneous value lower than that of the pulsating voltage and thereby driven with a low speed.

Title: Photomask
Inventor: FUJII KIYOSHI
IPC: G03F1/68
Filed: 1992-07-29
Abstract: PURPOSE:To provide the photomask which is uniform in the film thickness of phase shifters and enables the transfer of fine patterns by forming light shielding film patterns on the surface of a photomask substrate and forming the phase shifters on the rear surface of the photomask substrate in prescribed patterns. CONSTITUTION:The circuit patterns are formed of the light shielding film 2 on the front surface of the mask substrate 3 and the phase shifters 1 are formed in the prescribed pattern on the rear surface of the mask substrate 3. The production thereof is executed by a method of forming the light shielding film patterns on the front surface of the mask substrate 3, then forming the phase shifters 1 on the rear surface and processing the phase shifters to the necessary patterns. Since the phase shifters 1 are formed on the rear surfaces having no patterns, the formation of the phase shifters to a uniform film thickness is possible. As another embodiment, the phase shifters are formed on the mask substrate and after the phase shifters are wroked to the necessary patterns, the light shielding film is formed and is worked to the circuit patterns. Since the phase shifters are formed on the plane in such a case, the uniform film thickness is obtd. The light shielding film is formed on level differences and, therefore, the film thickness is nonuniform but does not affect exposing.

Title: Semiconductor-laser driving apparatus
Inventor: YAMAWAKI TAKESHI
IPC: H01S5/068
Filed: 1995-08-07
Abstract: PROBLEM TO BE SOLVED: To stabilize the laser output economically for the returning light generated with a SELFOC lens or the like by controlling semiconductor laser with a specified light emission output, wherein the output fluctuation becomes a specified rate or less, even it the laser light is bonded with the returning light from an external optical system. SOLUTION: The forward emitting light from a semiconductor laser 21 enters into a SELFOC lens 22 as the divergent bundle of rays and becomes a luminous flux L, which is approximately in parallel with an optical axis by the refractive-index distributing action of the SELFOC lens 22. Thus, the luminous flux L is emitted. Since one SELFOC lens 22 has the circular cylinder shape, the laser light is vertically emitted at an emitting surface Z. The laser light, which is reflected from the inner face of the emitting surface Z, is returned to the semiconductor laser 21 through the same optical path. In this case, even it the returning light is changed, the optical output/ current characteristicks are intersected at certain one point (steady point power).  When the semiconductor laser 21 is made to emit the light in the vicinity of the steady point power, the laser light becomes approximately constant even if the returning light is changed and can be stabilized at 10% or less of the allowable range of the fluctuation of the optical output.

Title: Phase synchronizing system of digital signal
Inventor: SHIMOE TOSHIO
IPC: H03L7/00
Filed: 1983-11-24
Abstract: PURPOSE:To reduce the phase jitter by dividing an input clock with a prescribed dividing ratio to obtain two low frequency clocks having a difference of phase by an amount equivalent to the pulse width of the input clock and selecting either one of both clocks. CONSTITUTION:When an input clock Ci is divided by a counter circuit CNT and the count value ''5'' is obtained, both a delay detection signal (b) and an advance detection signal (f) are fetched by flip-flops FF1 and FF0. The circuit CNT is set to measure the phase cycle of a low frequency clock C1. In this case, a low frequency clock C2 which is delayed by an amount equivalent to the width of the input clock is produced by a flip-flop FF2 which works on an inverted signal of the input clock. Then a flip-flop FF3 actuates a selection circuit SEL when signals (b) and (f) are detected, and a low frequency clock different from that selected previously is delivered. Thus the control is possible within a cycle of the input clock.
