Patent JP-S63207951-A (JP)
Title: Hot-water supplying apparatus utilizing solar heat
Inventor: MIYAMOTO KAZUHIKO
IPC: F24S90/00
Filed: 1987-02-21
Abstract: PURPOSE:To prevent the temperature distribution in the feed hot-water in a heat storage tank from becoming in layers due to the change in outdoor circumstances, by controlling the timing to stop a reversible flow water circulating pump and to reversely flow a circulating water at the same time a four-way valve is changed when a defrosting operation of a heat collector is carried out. CONSTITUTION:When a temperature sensor 13 senses the frosting state of a heat collector 7 and feeds a signal into a collector 14, the controller 14 stops the water circulating pump 10 which has been operated during a heat collecting operation. At the same time a four-way valve 2 is changed over to start a defrosting operation. A heat-exchanging temperature sensor 15, which has been detecting the temperature in the feed hot-water which was always heated during the heat collecting operation, feeds a signal that the temperature of the feed hot-water remaining in a heat exchanger 3 of cooling medium to water has lowered, into the controller 14. Receiving the signal, the controller 14 feeds a signal into the water circulating pump 10 to let it start a reversely circulating operation. The reversely circulating operation is continued until the heat-exchanging temperature sensor 15 senses that the heated feed hot-water from a heat storage tank 9 heats the heat exchanger of cooling medium to water sufficiently, and the completion of heating is detected by the heat-exchanging temperature sensor 15.

Abstract: PURPOSE:To set a breakdown voltage at a stable value, by deeply forming a high concentration impurity region in a collector region, and providing a protecting diode, which has a P-N junction having a broad current path between a base region and the collector region, in a semiconductor device. CONSTITUTION:In the surface of a collector region 1 neighboring a base region 2, P<+> type high concentration impurites of boron and the like having the same conducting type as the region 1 are doped by an ion implanting method. A P<+> type high concentration impurity region 4' is deeply formed by high temperature heat treatment. By the formation of the region 4', a P-N junction part 9' is formed between the region 2 and the region 4'. A protecting diode is formed within the semiconductor device. A surge absorbing circuit, wherein a protecting diode 10 is connected between a collector and a base, is constituted. Thus the semiconductor device itself is protected against the surge current. Since the current path at the junction part 9' becomes broad, the breakdown voltage is not fluctuated in correspondence with a reverse voltage when the reverse voltage is applied across the collector and the base. Therefore, the stable withstanding voltage can be set.

Title: Disturbance allowable digital timing apparatus and method
Inventor: KAARU EFU BEITEI
IPC: G06F1/04
Filed: 1988-02-24
Abstract: Computer timing apparatus enables two redundant strobe or clock elements (11, 12) to produce a single stream of timing pulses (CLK*), without interruption, when both elements are operating normally, and when one element fails. The apparatus incorporates a multi-stable stage (21, 22, 23, 24) and an output logic stage (25, 26, 27). The multi-stable stage detects state transitions in the input signals (CLK1, CLK2) of each clock element and generates a corresponding clock-tracking signal (TRACK1, TRACK2) which can disable the output of the corresponding clock from propagating through the output logic. The output logic stage logically combines each clock signal (CLK1 or CLK2) with its corresponding clock-tracking signal (TRACK1 or TRACK2), and logically combines the resultant signal to produce a single stream of output signals (CLK*) responsive to a next transition produced by either of the two strobe or clock elements.

Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To call, the following vehicle's attention and press it to reduce the speed so as to enhance the safety of traveling by bringing only the circular arc parts of a first spring piece pair or both the circular arc parts of the first spring piece pair and a second spring piece pair into contact to each other to light or flash a stop lamp. SOLUTION: When a vehicle is stopped for a short time by a red light, a stop lamp is lighted to call the following vehicle's attention by separating the first spring piece and second spring piece of a second spring piece pair 22. In a sudden braking, the downward operating distance of a brake pedal 40 is increased, and the distance of a rod 111 relatively moving outward beyond a stop lamp switch 20 is also increased. If the moving distance of the rod 111 exceeds the second spring piece pair 22, the second spring piece pair 22 is closed by elastic force, and a flasher 30 controls the stop lamp, so that it is quickly ON/OFF operated to produce a quick flash instruction effect. Thus, the following vehicle is urged to take a quick reaction, so that the collision can be prevented.

Title: Centrifugal vane
Inventor: TOUMACHI TAKAO
IPC: F04D29/28
Filed: 1979-04-04
Abstract: PURPOSE: To reduce the excessive stress generated in a vane by centrifugal force since a side plate may be supported so that its free radial deformation may be permitted by slidably engaging the tips of a plurality of support bars protruded from a core plate with a radial groove provided on the inside surface of the side plate.  
     CONSTITUTION: A plurality of support bars 7 are protruded from the core plate 3 of a vane 4, and guide portions 7a with a table shaped section are provided on their tips. A plurality of radial grooves 5a are provided on a side plate 5 correspondingly to the locations of the bars 7, and the guide portions 7a of the support bars 7 slidably engage with the grooves 5a. Thereby, the plate 5 is capable of sliding on the bars 7, not bound in radial direction and can be freely deformed. On rotation, therefore, the centrifugal force of the plate 5 is not transmitted to the vane 4 so that such bending stress as generated in conventional vanes is not generated at all. Therefore, the blades of the vane 4 can be considerably decreased in thickness and high speed can be developed by the vane 4.

Title: Tin or tin alloy plating material for terminal connector of electronic device, electric parts, etc., with superior surface contact resistance characteristics and manufacture thereof
Inventor: MARUO SATOSHI
IPC: C25D7/00
Filed: 1994-03-10
Abstract: PURPOSE:To obtain superior surface contact resistance characteristics by setting a specific value for the peak area ratio of PC (2p)/Sn (3d) of a plating surface obtained by X-ray photoelectric spectroscopy in a plating surface formed by applying tin or tin alloy plating on a copper or copper alloy. CONSTITUTION:Tin or tin alloy plating is applied on copper or copper alloy. The plating surface of the tin or tin alloy plating material is formed so that the peak area ratio of P (2p)/Sn (3d) on the tin or tin alloy plating surface obtained by X-ray photoelectric spectroscopy may be 0.03 to 0.05. If the peak area ratio is less than 0.003, the film is incomplete and oxydation of Sn may probably advance. On the other hand, if it exceeds 0.05, the film becomes thicker, and the contact resistance value on the plated surface may probably increase. The peak area of P (2p)/Sn (3d) can be controlled according to a electrolyzing time. When the electrolyzing time is longer or shorter, the peak area ratio of P (2p)/Sn (3d) is increased or decreased, respectively.
