Title: Pump with variable throttle body on its suction path
Inventor: YAMAMOTO KAZUYOSHI
IPC: F04D29/46
Filed: 1979-04-24
Abstract: PURPOSE: To perform smoothly the throttling of suction path according to the variation in the operating flow rate as well as prevent the occurrence of pulsative movement and cavitation by providing an elastic variable throttle body having the same effect as a throttle plate in the suction path of a pump.  
     CONSTITUTION: Since pressure is raised as a discharge flow rate reduces, a pressure is raised and applied to the ring variable throttle body 8 of an elastomer (e.g., rubber), provided on the periphery of a suction path, through the pressure reduction valve 10, and the variable throttle body 8 is expanded toward the radial direction of the suction path to cause a throttling action to take place smoothly without abruptly throttling the flow parth area, as shown at numeral 9. By the variable throttling, a part, or a swirl flow, of fluid subject to a large energy by the rotation of the impeller 1 is trapped between the impeller 1 and the deformed throttle body 9, and thus cannot be developed any more, so that pulsative movement and cavitation can be prevented.

IPC: H04N9/78
Filed: 1992-03-06
Abstract: PURPOSE:To unnecessitate the adjustment of a phase and a gain in a manufacturing process by detecting a burst signal remaining in a burst period from a separated Y signal, and controlling a phase and gain adjusting means so that an amplitude can be the minimum. CONSTITUTION:The Y signal outputted from an adder 6 is inputted to a gate circuit 9, and extracted only in the burst period by a burst gate pulse from a signal processing circuit. Burst components remaining in the extracted Y signal are amplified by an amplifier 10, and the amplitude is converted into a DC voltage by a detector 1. The DC voltage is converted into digital data by an A/D converter 12, and the control outputs of D/A converters 7 and 8 are changed based on the data by a control microcomputer 13. At that time, the minimum point of the DC voltage (the optimum adjusting point of the phase and gain of an Y/C separator circuit) is searched by using the prescribed algorithm of a two-dimensional retrieval Then, the outputs of the D/A converters 7 and 8 are transmitted respectively to a gain adjusting equipment 4 and a phase adjusting equipment 3.

Title: Radiation type fire detector
Inventor: MIYAMOTO AKIO
IPC: G08B17/12
Filed: 1987-03-06
Abstract: PURPOSE:To prevent a detector from malfunctioning by providing a 1st low-frequency amplifier, a 2nd low-frequency amplifier which amplifies a low-frequency output generated owing to higher harmonic noises generated by a pyroelectric element, and a differential amplifier. CONSTITUTION:When a pyroelectric element 21 generates high-frequency noises having a peak value at 170Hz owing to deterioration, the output of the high-frequency noises is amplified by a high frequency amplifier 33. Then, a low-frequency output which is generated with said output and has a peak value at 8Hz is amplified by a low-frequency amplifier 34 and inputted to a differential amplifier 5. The low frequency output which is generated with the high-frequency output and has its peak value at 8Hz is amplified by a low-frequency amplifier 31, adjusted by a phase matching circuit 4 to the same phase with the output of the amplifier 34, and inputted to the amplifier 5. Both those signals are equal in frequency and amplitude and in phase with each other, so the output of the amplifier 5 is zero and signals which cause malfunction, therefore, cancel each other. A comparator 7 maintains the low level through the operation of an offset circuit 71 and no fire signal is generated.

Filed: 1995-03-10
Abstract: PURPOSE: To improve the heat transfer characteristics of the whole core wherein fins/tubes are combined together by using a plate fin as a fin and an extrusion flat heat tube, having a plurality of small holes as a tube. CONSTITUTION: A heat-exchanger made of aluminum is constituted through combination of a plurality of plate fins 1 serving as a fin and a plurality of flat tube heat transfer tubes 2 having a plurality of small holes 4. A number of the fins 1 are vertically arranged at intervals of a given distance and flat heat transfer tubes 2 are arranged in such a state that the fin 1 group are inserted externally thereof at right angles therewith.

Abstract: PURPOSE:To prevent dew condensation on the surface of panel, by forming a space part with a moisture absorbing body, which is obtained by filling and keeping a hygroscopic filler into fine voids of porous panel, and a cover member having moisture-insulating layer on the inner circumferential side of the member. CONSTITUTION:The titled structures is provided in such a manner that the moisture absorbing body is attached to face the inside of room and the cover member is attached to face the outside of room. Then, because it is higher temp. and higher moisture at the inside of room and it is lower temp. and lower moisture at the outside of room in winter, etc., the air having a pressure near to a saturated steam pressure which passes through the moisture absorbing body and exists in the space 4, which is composed of the cover member 3 and the reverse side of the moisture absorbing body 1, is cooled, condenses to dew on the cover member and then naturally drops down. The steam pressure in the space part 4 is lowered due to the dew condensation. Thereby, the moisture is blown off from the reverse surface of the moisture absorbing body 1 and the moisture the inside of the moisture absorbing body 1 is moved to the reverse side of said body. Therefore, the moisture in room is blown off outer the system and removed without necessitating external energy.
