Patent JP-H0442723-A (JP)
Title: Motor controller
Inventor: AKAHA TSUTOMU
IPC: H02P29/00
Filed: 1990-06-08
Abstract: PURPOSE:To obtain a motor controller which can normally monitor disconnection with reduced power consumption by feeding the exciting coil of an electromagnetic contactor with a check current low enough not to operate the electromagnetic contactor and then judging abnormality such as disconnection based on the magnitude of the check current. CONSTITUTION:Exciting coils 7a, 9a, 10a are normally fed with low check current intermittently from a monitoring power supply circuit 24 with a predetermined period. Magnitude of the check current is detected through a current detecting circuit 27 and a detection signal is fed to a comparing circuit 29 where it is compared with a normal set value. When the check current drops below the set value, a disconnection detection signal is provided to a display and an alarm is outputted. Since the check current is low enough not to actuate an electromagnetic contactor, power loss is reduced and since the auxiliary contact of the electromagnetic contactor is not required as a disconnection detecting means, the controller can be implemented in an electronic circuit resulting in a high operational reliability.

Title: Hot water feeding device combined with air conditioner
Inventor: ISHII KATSUMI
IPC: F24D17/02
Filed: 1981-09-18
Abstract: PURPOSE:To achieve a high efficiency with a small capacity heater by priority control of the action of a hot water feeding circuit in the combination of the temperature of a boiler water, a hot water circuit utilizing signal and a heating circuit controlling signal for a hot water feeding heating system of a single can/2-circuit type boiler. CONSTITUTION:A boiler water temperature detector 4 is heated with a heater 2 within a set temperature range to raise the temperature of the boiler water. The boiler water temperature detector 4 and a controller 5 combines to start or stop a circulation pump 6 within a specified temperature range of the boiler water temperature. When detecting the utilization of a hot water feeding circuit, a hot water feeding circuit utilization detector 8 and a controller 5 combine to start or stop the circulation pump 6 to prefer the hot water feeding circuit. This can make the heater 2 smaller in the capacity to shorten the heating stoppage time during the simultaneous operation of feeding hot water and heating. Thus, the lowering of the room temperature can be prevented thereby improving the efficiency.

Abstract: PROBLEM TO BE SOLVED: To obtain an alloy material having a hardened layer to improve wear resistance, fatigue strength, etc., on the surface by forming a hardened layer of an intermetallic compound, which is essentially composed of Ti and Cu or Ti and Ni, on the surface. SOLUTION: On the surface of a Ti base alloy material, a hardened layer of an intermetallic compound, which is essentially composed of Ti and Cu or Ni is formed by applying Cu or Ni plating and then subjecting to a diffusion heat treatment in a non-oxidation atmosphere at 500-1,000 deg.C, if necessary, subjecting to shot peening or shot blasting. A Cu or Ni plating method may be any one of electrolytic plating, chemical plating, CVD, PVD, etc., but electrolytic plating is relatively simple. Adhesiveness of Cu and Ni plating layers is not important because of executing a subsequent diffusion heat treatment. Ti base alloy materials to be used are Ti-6Al-4V, Ti-3Al-2.5V, Ti-4Al-2.5V-4Mo-2 Sn-0.5Si, Ti-7Al-4Mo, Ti-8Mn, etc.

CONSTITUTION:A photoresist layer 2 is formed on a substrate 1 made of glass, etc., and the laser light condensed by a lens 3 is exposed to form an exposed part 4 on the substrate. Then the part 4 is removed by developing and fixing, and Cr, etc. is vapor- deposited over the entire surface of the substrate 1. A lift-off process is applied after removing the layer 2 and Cr on the layer 2 to obtain the 1st recessing/projecting part 6. Then a chalcogenite glass layer 7A and then a metallic layer 7B of Cu, Al, etc. are vapor-deposited to form a recessing/projecting forming layer 7. Then the laser light is condensed to form a part 7C where the metal of the layer 7B is doped to the layer 7A. The layer 7 is removed by excluding the part 7C to obtain the 2nd recessing/projecting part 11. The parts 6 and 11 are used as a tracking guide and a signal information pit, respectively. In such a way, a master disk is easily produced for an optical information storing medium having high accuracy.
