Patent JP-H057143-A (JP)
Title: Solid-state relay
Inventor: NOZAKI YUTAKA
IPC: H03K17/78
Filed: 1991-06-27
Abstract: PURPOSE:To prevent reverse-trigger of a triac by using a photocoupler of a power MOSFET for a trigger circuit of the triac and preventing current supply of a zero cross circuit from being given to a gate of the triac. CONSTITUTION:An AC signal is full-wave-rectified by a diode stack circuit DS and the result is divided by voltage division circuits R13, R14. When the divided voltage reaches a prescribed voltage or over, a 1st photocoupler PC1 is turned on When an AC voltage stays at a zero cross point, the divided voltage is less than the prescribed voltage and the photocoupler PC1 is not turned on. When an input signal is applied while the photocoupler PC1 is turned on, a 2nd photocoupler PC2 is not turned on, However, when the AC signal reaches a zero cross point in the presence of the input signal and the photocoupler PC1 is turned off, the photocoupler PC2 is turned on and an output power MOSFET is turned on to trigger a triac TR, which is turned on. Since a gate current flows to the triac TR only at the trigger in this circuit, the reverse- trigger of the triac TR is prevented.

Title: Method of rolling shape steel
Inventor: FUJIMOTO YOJI
IPC: B21B1/088
Filed: 1988-06-27
Abstract: PURPOSE:To decrease roll assembly operations by rolling down rolling reductions which roll own the web-corresponding part of a shape steel in the thickness direction thereof and are variable in roll widths and the web-corresponding part in the transverse direction thereof, thereby adjusting the web height. CONSTITUTION:The conventional constitution is adopted for a break down mill BD1 to the E3 mill of a rough universal group and the width variable rolls are installed to the horizontal rolls H of a finish universal mill UF. While the inside width A of the rough H-shaped steel to the U5 mill is the roll width A of the horizontal roll of the U5 mill, the roll width of the UF mill is previously set at A>B and the steel is rolled down by A-B=S (squeeze quantity) by the vertical rolls V of the UF mill in a finish rolling stage. This S is determined by the inside width of the target product. The flange parts are so raised as to be perpendicular to the web part and the web height is rolled down in this cross rolling reduction. The shape steel having the specified web height is produced with the fewer number of rolls in this way and th common use of the rolls is possible for production of the shape steels having less dimensional difference of the web height.

Title: Electronic circuit case provided with heat removing structure
Inventor: SATO KENICHI
IPC: H05K7/20
Filed: 1994-07-08
Abstract: PURPOSE:To provide an electronic circuit case provided with a heat removing structure that is excellent in heat removing capability and thus enables heat removal in environments containing water or dust. CONSTITUTION:An electronic circuit case 1 is provided with heat removing structure: Outer fins 3 and inner fins 4 are formed outside and inside a circumferential wall 2, respectively; these fins 3, 4 are thermally coupled with each other. The inner fins 4 on the circumferential wall 2 of the electronic circuit case 1 are placed in proximity to heating elements 5, such as dropper resistors. The inner fins 4 absorb heat generated from a heating element 5. The absorbed heat is efficiently transmitted to the outer fins 3, through which the heat is removed by radiation or the like. In brief the inner fins absorb heat, and the outer fins radiate it. If electric parts involving heating are housed in a small space, as a result, heat is efficiently removed. This prevents excessive temperature rise within an electronic circuit case, and eliminates the influence of heat oh other parts.

Abstract: PURPOSE:To suppress the power of the shaft of a blower at low value, and to eliminate the need for installation of a muffler by arranging an air preheater at the suction side of air for combustion of the blower and elevating the temperature of air for combustion flowing into the blower. CONSTITUTION:Air A for combustion flows into the steam type air preheater 6 by the sucking force of the blower 7. The steam type air preheater 6 also functions as the adjustment of the flow of air A for combustion violently flowing toward the blower 7 by the action of a heat transfer pipe, etc. incorporated. Accordingly, strong suck-in sounds are reduced by mounting the air preheater 6, and the muffler need not be installed particularly. Since air A for combustion, temperature thereof is elevated by the steam type air preheater 6, flows into the blower 7, the density of air for combustion lowers, and the power of the shaft of the blower 7 is suppressed at low value.
