Title: Electric water heater
Inventor: FUJISHIMA MICHIYUKI
IPC: F24H1/18
Filed: 1987-11-19
Abstract: PURPOSE:To prevent uneconomical consumption of power, by a method wherein, from a maximum energizing time in a specified period and an energizing time to compensate the dissipated heat, the presence of the use of hot water is decided, and based on the decided result, energization of a heat generating body and an anticorrosion source device is controlled. CONSTITUTION:Since a time switch 5 is turned ON only one time a day, the number of days on which it is turned ON is stored in a number of days memory device 15. An energizing time to a heat generating body 2 per a day is stored on an energizing time memory device 13. When the specified number of days elapses, a maximum energizing time during this period is determined by means of a computing device A 16, and it is HMAX. A computing device B 17 detects the water temperature of the lower part of a tank 1 right after turning ON of the timer switch 5 by means of a water temperature detecting sensor 11, calculates a heat dissipation loss of a hot water temperature per day of a tank 1 from the detecting value, and computes a given energizing time HL to the heat generating body 2 on a day subsequent to a time when hot water is not used. The HL is compared with the HMAX, and when it is decided by a deciding device 18 that hot water is not used during this period, energization to the heat generating body 2 and an anticorrosion source device 8 is stopped by means of an energization control device 19.

Title: Stroboscopic device and camera equipped therewith
Inventor: OTAKA YUKIO
IPC: G03B15/05
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To prevent deformation caused by the heat of a prism. SOLUTION: In a flash mode, a control circuit actuates a temperature detection circuit to measure and detect the temperature of a reflector coming in contact with the prism (step S20). At a next step S21, whether the detected temperature is equal to or lower than the specified temperature is decided. When it is equal to or lower than the specified temperature, the charging of a stroboscope at and after step S25 is performed. When it is higher than the specified temperature, operation is shifted to a step S22 so as to start a heat radiation timer. After starting the heat radiation timer, the elapse of the specified timer time (for example, for several seconds) is awaited(step S23), and after the elapse of the specified time, the operation is shifted to a step S24 so as to reset and stop the heat radiation timer.  Then, the operation is returned to the step S20, the temperature of the reflector is measured by the temperature detection circuit again and processing of steps S21 to S24 is repeated until the temperature of the reflector is equal to or lower than the specified temperature.

Filed: 1985-12-28
Abstract: PURPOSE:To eliminate the torque ripple of a single-phase brushless motor by superposing two triangular waves in the waveform of a magnetic flux density of a magnet or a rotor. CONSTITUTION:The magnetizing distribution of the magnet of a rotor is formed in a combined waveform C by superposing the triangular wave A having 2pi/m of period and amplitude (b) and a triangular wave having pi/m and amplitude b/4 by bringing the peak positions in coincidence. Thus, a single-phase motor having no torque ripple can be obtained. In the drawing, the case of m=1 is shown. The period function of pi/2m of period and -b/4 of the minimum value is superposed on the magnetization distribution by bringing the minimum values in coincidence with the peak position of the combined waveform to increase the torque with the maximum magnetic flux density constant.

Title: Piston returning mechanism of disc brake
Inventor: NAKAJIMA SHIRO
IPC: F16D65/18
Filed: 1991-11-11
Abstract: PURPOSE:To fix a return amount of a piston according to the size of load fluid pressure when a piston is returned by the elastic restoring force of a rubber ring at the time of releasing pressure of a hydraulic oil pressure system. CONSTITUTION:An elastic ring 7 which is harder and has a higher elastic coefficient than a rubber ring 4 is installed between a sealing groove 5 on the inner surface of a cylinder 2 and an edge surface on an opposite side of fluid pressure of the rubber ring 4 for fluid sealing which is inserted into the groove and is fitted with an interference on the periphery of a piston 3. A space 6 which allows deformation of an elastic ring 7 is formed between the sealing groove 5 and the elastic ring 7, and the second space 8 is formed between the elastic ring 1 and the rubber ring 4 if necessary. As load fluid pressure rises, deformation of the elastic ring 7 increases, and a substantial chamfered amount (size of the space) which determines elastic deformation amount of a rubber ring 4 increases, so that the piston returning amount, increases according to fluid pressure. It is thus possible to solve the problem of an increase in dragging torque due to shortage of the piston returning amount, after high pressure is applied without an increase in the piston stroke when low pressure is applied.

Abstract: PROBLEM TO BE SOLVED: To execute an automatic light control action without depending on the reflectivity of a film when a flash-photographing action is executed by providing a camera with a light control element executing a photometry action in order to obtain data for controlling light by using the light of a part of luminous flux for a finder. SOLUTION: This camera is constituted so that a diffusion plate P1 is arranged at the position of a primary image surface I1 and provided with the element for controlling light SL executing the photometry action in order to obtain the data for controlling light by using the light from the plate P1. Besides, it is provided with a photometry element SE executing the photometry action of steady light by using the luminous flux fetched as one part of the luminous flux for a finder by splitting the luminous flux for a finder by a half mirror HM2. Since the primary image equivalent to an image formed by luminous flux for photographing is formed on the plate P1, the focusing state of a photographing optical system can be confirmed through a finder. Then, since the plate P1 is used, the focusing state of the photographing optical system is confirmed.  Besides, since the light reflected from a film surface N1 is not used, a correcting action corresponding to the type of the film need not be executed.

This thereby lessens the burden of a brake equipment so that the cage can be quickly decelerated.

Title: Frequency control circuit
Inventor: TANAKA HIROYUKI
IPC: H04B7/155
Filed: 1988-11-22
Abstract: PURPOSE:To obtain frequency control suitable for various signals with different transmission speeds by constituting a low pass filter provided to a feedback loop with plural low pass filters connected in parallel and with different cut-off frequencies and switching the filters selectively with a controller in response to the transmission speed. CONSTITUTION:A phase frequency detector 4 is so constituted that 3 low pass filters 6A-6C are connected in parallel and a voltage controlled oscillator 9 is connected to one of the filters selectively by a switch 8. The cut-off frequency of the low pass filters 6A-6C differs from each other and the cut-off frequency is set larger in the order of the low pass filters 8. In the case of selecting the low pass filter 6A whose cut-off frequency is lowest, since the loop band of the feedback loop is made narrow to increase the frequency stability for a long period thereby enabling to pass through a signal of a low transmission speed. In the case of selecting the low pass filter 6C whose cut-off frequency is highest, since the loop band is widened, the frequency lock range is widened, the circuit is immune to the frequency drift and suitable for the high speed transmission.
