Title: Switching method for resonance type dc-dc converter circuit
Inventor: SUZUKI TOSHIYASU
IPC: H02M3/28
Filed: 1991-06-01
Abstract: PURPOSE:To fix the maximum absolute value of a voltage across both ends of a parallel resonance circuit so as to control the voltage of a capacitor to a fixed level by connecting in parallel a constant-voltage means having a two- way constant-voltage characteristic with the parallel resonance circuit in a DC-DC converter. CONSTITUTION:A coil 104 and capacitor 106, two diodes 22 connected in reverse parallel with each other, and a coil 4 and capacitor 6 respectively constitute a parallel circuit, two-way constant-voltage means, and series resonance circuit. A capacitor 62 is equivalently connected in series to both resonance circuits through a transformer 128 and rectifying means 26. Another rectifying means 126 clamps the maximum absolute value of the input AC voltage of the transformer 128 at a value corresponding to the voltage value and turn ratio of a DC power source 1. Therefore, the voltage of the capacitor 62 can be stabilized at a fixed level. An astable multivibrator 101 alternately triggers monostable multivibrators 102 and 103 by using its positive output and complementary output so as to maintain switches 104 and 105 at turned-on states.

Title: Package automatic program controller
Inventor: YAMADA KOICHI

Filed: 1989-09-05
Abstract: PURPOSE:To eliminate the need for a time code recording before integral one cassette edit even when a VTR cassette with no time code recorded thereto is in use by providing a means of a package automatic program controller discriminating the edit mode of a VTR. CONSTITUTION:A VTR control discrimination means 3 discriminates whether a recording medium is recorded till the end from a midpoint or part of recording is replaced based on an information data obtained from a data discrimination means 1a and when it is discriminated as the recording from the midpoint till the end, a midpoint recording mode section of the VTR control means 4 is driven to control the VTR in the mode making the recording on the midpoint. Moreover, when part of replacement is discriminated, the replacement recording mode of the VTR control means 4 is driven to control the VTR in the replacement recording mode. Thus, even when a VTR cassette with no time code recorded thereon is in use, the time code recording prior to integral one cassette edit is not required.

Abstract: PURPOSE:To realize the small sized and simple sound pressure provision device for measuring and calibrating the microphone characteristic not requiring installation such as an anechoic chamber. CONSTITUTION:A large sound pressure provision device is provided with a pressure chamber varying means consisting of a casing in which two cup shaped main bodies 1,2 are screwed directly indirectly to partition a pressure chamber 3 freely adjusting the volume, of a piston 11 reciprocating with a cylinder hole 10 opened toward the pressure chamber and the operation of a cam 7, and with a microphone mount part 12 in which a measured microphone is mounted to the casing in a way of facing the pressure chamber with air-tightness member 15. Since the volume V of the pressure chamber is increased in a range of DELTAV=2AS with the reciprocation at a prescribed stroke of a piston caused by the periodic operation of the cam, the inner pressure in the pressure chamber is increased/decreased in a range of DELTA=KX(DELTAV/V) periodically, resulting that a sound pressure DELTAP adjusted optionally is exerted to the microphone.

Abstract: PURPOSE:To prevent the adhesion of ice and snow by mounting a heat-insulating material coating around the heating section of a heat pipe and previously installing a low Curie-point magnetic heating element to the heating section of the heat pipe in a device thawing snow adhering on an aerial wire. CONSTITUTION:Iron loss is generated by the transmission currents of an aerial wire 1 and heat is generated at a high temperature in a low Curie-point magnetic heating element 2 by setting up the low Curie-point magnetic heating element 2 and a spiral heat pipe 3 to the aerial wire 1, the heating section 4 of the heat pipe 3 is heated by heat generation of the heating element 2, and the heat is dissipated in a heat dissipating section 5.

Title: Cooling system for vehicular internal combustion engine
Inventor: AOKI SHINJI
IPC: F01P7/16
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To sufficiently cool both transmission oil and engine oil even when the load of an engine becomes high by making cooling water, flowing out of a radiator, flow into an oil changer. SOLUTION: When the load of an engine 1 exceeds the specified value, cooling water cooled by a radiator 2 is made flow into an A/T heat exchanger 11 and an E/O heat exchanger 12. Transmission oil and engine oil can thereby be cooled sufficiently by both heat exchangers 11, 12. As a result, lubricating failure can be prevented, so that friction loss at the sliding parts of an engine and a transmission is prevented to improve fuel consumption. Since cooling water cooled by the radiator 2 is partially diverged and used to cool both oil, the cooling quantity of the engine 1 is reduced, but the flow quantity to flow to an oil cooling waterway 103 is a small quantity, so that influence on the engine 1 can be almost disregarded.

Title: Self-priming pump
Inventor: ISHII MASATOSHI
IPC: F04D9/02
Filed: 1994-09-27
Abstract: PURPOSE: To reduce synthetic pressure variation and noises by allowing the pressure fluctuation near one communication hole when one blade passes one communication hole and the pressure fluctuation when the other blade passes the other communication hole to cancel each other. CONSTITUTION: In predetermined positions of a partition plate 7 constituting a partition wall 6, communication holes 61, 12 for introducing priming from a tank chamber into an impeller chamber 21, a central communication hole 63 for introducing water into the impeller chamber 21 and an upper communication hole 64 for discharging water urged by the impeller 4 are formed. The relative positions of the communication holes 61, 12 are set such that as soon as one blade 41 of the impeller 4 below the partition plate 7 passes completely the front face of one communication hole 61, the other blade 42 begins to pass the front face of the other communication hole 62.  Thus, the maximum value of pressure fluctuation near one communication hole 61 and the minimum valve of pressure variation near the other communication hole 62 cancel each other, so that the width of the pressure fluctuation and noises are reduced.
