Title: Controller for motor
Inventor: SETO MAKOTO
IPC: H02P23/16
Filed: 1983-04-30
Abstract: PURPOSE:To obtain a fast speed response by supplying a DC current corresponding to a variation in a load torque by a variable control rectifier when the torque is varied, thereby suppressing the variation in a voltage. CONSTITUTION:A speed controller 15 multiplies by a current controller 13 a speed controller 9 by the output of a speed instruction unit 7 by a multiplier 16, and the output is led directly thereto. Accordingly, even when a load torque is abruptly varied so that the output of the controller 9 is rapidly altered, torque current is supplied quickly to a variable control rectifier 1, and the only exciting current of a motor 6 is flowed to a condenser 2b of a DC intermediate circuit. Consequently, the variation in the voltage is suppressed to obtain a rapid speed response.

Title: Optical range finder
Inventor: TAKESHIMA AKIRA
IPC: G01S7/48
Filed: 1993-04-05
Abstract: PURPOSE:To provide an optical range finder which is available in a simple manner and high in precision. CONSTITUTION:The laser beam radiated from a laser diode LD20 is irradiated to a target object, passing through a fiber 21. An avalanche photodiode APD 29 detects the laser beam which is reflected by the article and returned. As for a phase comparator 32, the DC output component becomes zero under the condition that the phase difference between the laser beam radiated from the LD20 and the laser beam detected by the APD 29 becomes pi/2. Accordingly, when the output frequency of a VCO 35 is fixed through the phase lock, the output frequency always becomes the frequency corresponding to the distance from the LD20 to the target article. Accordingly, when the output frequency of the VCO 35 is monitored by a frequency detection part 41, the distance to the article at a certain time can be found in a simple manner with high precision, on the basis of the output frequency at this time.

IPC: G10L13/00
Filed: 1990-03-27
Abstract: PURPOSE:To obtain a desired synthesized tone equipped originally with reading, accent, intonation and breath, etc., which are originally controlled by a user, with simple configuration by providing mode set and control parts. CONSTITUTION:When the mode set part 40 selects any one of modes such as a text/ sound conversion mode, phoneme sound and meter symbol train output mode and phoneme sound and meter symbol train synthesizing mode according to a designation from an external part, the control part 50 discriminates the mode and controls the input/output of a text and a phoneme sound and meter symbol train. When the text/ sound conversion mode is set, the control part 50 inputs the text and a text analysis part 30 analyzes the text. Then, the result of the analysis is inparted through a sound synthesizing part 60 to a loudspeaker 61. When the phoneme sound and meter symbol train output mode is set, the control part 50 analyzes the text at the text analysis part 30 and outputs the generated pheneme sound and meter symbol train in the form of a character code to the external part. When the phoneme sound and meter symbol train synthesizing mode is set, the control part 50 directly outputs the phoneme sound and meter symbol train inputted from the external part, through the sound synthesizing part 60. Thus, the user can freely change the pheneme sound and meter symbol train and easily obtain the desired synthesized tone.

Title: Case for integrated circuit
Inventor: AMAMIYA YOSHIHITO
IPC: H01L23/02
Filed: 1985-04-15
Abstract: PURPOSE:To lighten a case for an integrated circuit without lowering the shielding effect of charged particles by making the thickness of a shielding plate larger than other sections in at least one of a section just above a chip- mounting position or a section just under the position. CONSTITUTION:Since charged particles projected (points A' A'' B' S) to a section S to be protected on a chip 1 from the oblique direction travel at a distance A', B' longer than the thickness t0 of a shielding film 2, the section of residual length A', A'' obtained by subtracting length A'', B' corresponding to thickness t0 from the distance A', B' is unnecessitated from the viewpoint of shielding action. Even when there is not shield in the section of length A', A'' and the thickness of a shielding plate at the point A'' takes thickness t0 smaller than thickness t0 at that time, no trouble is generated actually. Consequently, the shielding plate 2 is formed to a shape shown by a broken line, thinned with approaching to a peripheral section and can be lightened. The shielding plate need not be taken in unlimited size actually, and set in limited size in an extent that the projection of charged particles from a side surface is not at issue.

IPC: H01L21/268
Filed: 1989-03-31
Abstract: PURPOSE:To enable a thin film with a uniform profile to be formed by irradiating laser while changing the shape of opening properly. CONSTITUTION:After an opening is formed into a desired shape 21, laser is irradiated, and then a thin film is formed to some extent, the opening is narrowed 22 and is gradually opened 22-24 while being irradiated with laser. Then, the shortage of film thickness at the central part of an initial stage 25 is gradually compensated for as an increment 26 due to a second irradiation, an increment 27 due to a third irradiation, and an increment 28 due to a fourth irradiation. The width of the opening to be narrowed and the rate for expanding the opening should be set to an appropriate value. Thus, it is possible to form a thin film with nearly a uniform thickness as a whole although there are small protruding and recessed parts.
