Title: Semiconductor power conversion apparatus
Inventor: YAMAMOTO HIROSHI
IPC: H01L23/34
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor power conversion apparatus, in which a rise in the temperature of a semiconductor element can be reduced efficiently, without making a cooling fin large-sized. SOLUTION: A wiring board is attached to the side of terminals of semiconductor elements 1. A cooling fin 4 is attached to the side of a base. The wiring board comprises a plurality of wiring conductors 2a, 2b, 2c which are manufactured of, e.g. a copper thin plate so as to make its surface area large. The flow of the air is formed inside an apparatus through the use of respective fans 3. Heat which is generated inside the semiconductor elements 1 is conducted to the cooling fin 4, and it is conducted also to the wiring board. The heat which is conducted to the cooling fin 4 is diffused by the air which flows in the cooling fin 4. The heat which is conducted to the wiring board is diffused by the air which flows on the side of the wiring board.

Title: Handle of saw
Inventor: MIYAWAKI UICHI
IPC: B27B21/04
Filed: 1987-12-28
Abstract: PURPOSE:To lightly and easily perform a cutting work by providing a cut assistant member extending parallel to a handle body on which a saw blade is mounted, a retainer for an article to be sawed attached to the assistant member, and a moving guide member for guiding the handle body along the member. CONSTITUTION:When the handle 13 of a rock preventive rod 3 is grasped by a left hand, the grip 5 of a handle body 2 is grasped by a right hand to be worked, an abutment part 9 of a branch retainer 8 is pressed in contact with the branch of a tree to be cut, the handle 13 is so tightly grasped in this state as not to move the rod 3, and the branch is cut by teeth 12. When the body 2 is pulled down, the teeth 12 are engaged with the branch to be cut, and the branch tends to rock by this resistance in the pulling direction. However, since the branch is retained by the retainer 8, it cannot move. Eventually, the teeth 12 are smoothly intruded into the branch. Accordingly, when the branch of a high tree is sheared, the branch to be cut is not rocked, thereby lightly and easily perform the cutting work.

Abstract: PURPOSE:To reduce the primary variation of the temperature of hot water discharged with the opening-closing operation of a changeover valve remarkably by controlling the temperature of a hot-water supply equipment so that a firing rate immediately after the opening of the changeover valve is made larger than that immediately before the opening of the changeover valve and a firing rate immediately after the closing of the changeover valve is made smaller than that immediately before the closing of the valve. CONSTITUTION:A proportional valve 11 for controlling the flow rate of a gas fed to a plurality of gas burners 2 and a changeover valve 17 interrupting the supply of the gas to the gas burners as one part of a plurality of the gas burners 2 installed on the downstream side of the proportional valve 11 are provided. The changeover valve 17 is opened and all the gas burners 2 are ignited when the opening of the proportional valve 11 is made larger than specified opening, the changeover valve 17 is closed and part of the burners 2 are turned off when the opening of the proportional valve 11 is made smaller than the specified opening. The temperature of a hot-water supply equipment is controlled so that the opening of the proportional valve 11 is increased and a firing rate immediately after the opening of the changeover valve 17 is made larger than that immediately before the opening of the changeover valve 17. The temperature of the equipment is so controlled that the opening of the proportional valve 11 is reduced and a firing rate immediately after the closing of the changeover valve 17 is made smaller than that immediately before the closing of the changeover valve 17, thus inhibiting the variation of the temperature of hot water discharged with the opening-closing operation of the changeover valve.

Title: Projection lens and image projection device using it
Inventor: OKUYAMA ATSUSHI
IPC: G02B15/177
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To obtain a projection lens projecting the original picture of a projection image by excellently correcting trapezoidal distortion or distortion aberration in an oblique direction by allowing the projection lens to have at least one lens surface without axial symmetric property. SOLUTION: The projection lens LP is provided with two lens groups L1 and L2 and a variable power action is executed to a telephone end from a wide angle end by moving both groups to a screen S side so that a gap between them is reduced. Thus, the size of the projection image projected on the screen S can be varied. That means, the screen S and the projection image LCD are mutually in parallel and both of them are orthogonally crossed in the optical axis Ax direction of the lens LP. Then, the projection image is enlarged and projected with the various kinds of magnification on the screen S by the lens LP. Besides, the lens surface ZRN without the axial symmetric property is used as the lens surface (r1) of the group L1 on the screen S side. By using the aspherical surface ZRN without the axial symmetric property in such a way, the various kinds of aberration (distortion) is effectively corrected.

Title: Stereo matrix circuit
Inventor: MATSUKI HIROFUMI
IPC: H04H1/00
Filed: 1988-12-27
Abstract: PURPOSE:To reduce a noise when a mode is switched by suppressing the fluctuation of a direct current potential to be generated at the time of the mode switch. CONSTITUTION:A direct current flowing to the emitter side of transistors Q3 and Q4 and a direct current flowing to the emitter side of transistors Q5 and Q6 are equally I1 and at the time of the stereo mode, the I1 flows through the transistor Q3 to an output point (a). Then, at the time of a monaural mode, the I1 flows through the transistor Q5. Samely, the I1 flows respectively through the transistor Q6 at the time of the stereo mode and through the transistor Q4 at the time of the monaural mode to an output point (b). Accordingly, the direct current to appear in the respective output points (a) and (b) is same at the time of the stereo mode and monaural mode. It is same even in a transient state as well. Thus, when the mode is switched from one mode to the other mode, the change of the direct current is not generated in output terminals 11 and 12. Accordingly, the noise can be reduce when the mode is switched.

IPC: B32B27/32
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To give a shock resistance and a resistance to a severe thermal sterilizing conditions to the multilayered sheet by a method wherein the multilayered sheet consists of two layers, one of which is a sealing layer having a peeling function and being made of a mixture of a high density polyethylene-based resin and a specified straight chain-like low density polyethylene-based resin, and the other of which is an adjacent layer outside the sealing layer made of a polyolefin-based resin, or more. SOLUTION: The multilayered sheet has at least two layers, one of which is a sealing layer made of a mixture of a high density polyethylene-based resin (henceforth expressed as HDPE) and a straight chain-like low density polyethylene-based resin (henceforth expressed as m-LLDPE) polymerized with a metallocene-based single site catalyst and the other of which is an adjacent layer outside the sealing layer is made of polyolefin-based resin, or more. The sealing layer consists of 95-30wt.% of HDPE and 5-70wt.% of m-LLDPE and the obtained sheet can have a favorable easy openability, shock resistance and heat resistance. When the m-LLDPE exceeds 70wt.%, the cutting properties of the obtained sheet lowers and the external appearance of an opened surface is marred owing to its napping and stringiness. When the m-LLDPE is below 5wt.%, no shock resistance is obtained.  Further, the thickness of the sealing layer is set to be 5-25μm.
