Title: Production-process controlling system
Inventor: NAGATA HISAO
IPC: G05B19/418
Filed: 1986-10-06
Abstract: PURPOSE:To make it possible to change and add production steps, by writing the address of the next step when the production step is changed in a next-step address-information area, and using the addresses for the new step, change in step sequence and the like. CONSTITUTION:An address control device 3 outputs an address signal AD, which specifies the address of the initial production step in the preset production process, and reads the address information of the next step of said specified address. When a next-step specifying signal NX is inputted and the already written address information of the next step is at the initial state of a memory medium, the addresses in the sequence of the preset steps are specified. When the address is the specific address, an address signal, which specifies the specific address, is outputted. Then, the address information of the next step is updated to the address information of the next step in the address specified by said address signal AD. Then, the change in step sequence and addition of the production steps can be performed by writing in the address-information area of the associated next step and writing in the information area of the unit step in the new production step. The change in step sequence and the addition of the production steps can be readily performed in a short time.

Title: Sensor and safety device
Inventor: SUZUKI TAKASHI
IPC: B23Q11/00
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a safety device and a sensor capable of detecting whether or not a human body is present only in a desired area. SOLUTION: This sensor 22 comprises a pair of electrode plates 26, 28 oppositely arranged to have a predetermined gap between them, and guard plates 30, 32 and shield plates 30', 32' arranged at positions opposed to the electrodes 26, 28 respectively on sides opposite to the gap, and grounded. The sensor 22 can detect whether or not part of a human body is present between the electrode plates 26, 28, by sensing changes of capacitance between the electrode plates 26, 28. Presence of the guard plates 30, 32 and shield plates 30', 32' prevents the formation of electric fields on back sides of the electrode plates 26, 28 thereby limiting a detection area to an area between the electrode plates 26, 28. Accordingly, false detection is prevented. A safety device 24 using the sensor 22 can certainly operate only in a required area.

Abstract: PURPOSE:To improve the entire power efficiency by preventing a phase difference of a signals inputted from 1st, 2nd class C amplifiers to a power amplifier from being larger than a prescribed value and keeping the amplitude constant. CONSTITUTION:Whether or not a modulation phase difference between in-phase component I1, orthogonal component Q1 of a 1st modulation signal and in-phase component I2, orthogonal component Q2 of a 2nd modulation signal is larger than a prescribed modulation phase difference is discriminated and when not larger, 1st and 2nd modulation signals of a 1st arithmetic means 5 are selected and when larger, 3rd and 4th modulation signals of a 2nd arithmetic circuit 12 are selected. Moreover, a bias voltage is fed to 1st, 2nd class C amplifiers 8, 9 so that the amplitude of the signal amplified by the 1st, 2nd class C amplifiers 8, 9 is constant. Thus, the phase difference of the signal inputted from the 1st, 2nd class C amplifiers 8, 9 to the power amplifier 10 is not larger than a prescribed value and the amplitude is made constant. Thus, the power loss of the power synthesizer is reduced and the entire power efficiency is improved.
