Abstract: PURPOSE: To prevent the explosion of a boiler body by connecting a water tank having water surface level lower than the height of the top of the boiler body through a connecting pipe to the boiler body and retaining the pressure in the boiler body always lower than the atmospheric pressure.  
     CONSTITUTION: The water tank 2 is installed, for example, lower than the floor surface so as to have the water surface level 2a lower than the top 1a of the boiler body 1 attached with a burner 4, and the tank 2 is connected through a connecting pipe 3 to the boiler body 1. A level detecting container 7 for detecting the water surface level of the water in the boiler body 1 is connected to the top 1a of the boiler body, and the top of the container 7 is connected through a gas suction tube 10 to a vacuum pump 9, which is operated when the water level in the container 7 drops to predetermined level and stopped when it rises to predetermined level under the control. Thus, the gas in the container 7 is intaken to retain the pressure in the boiler body 1 lower than the atmospheric pressure.

Filed: 1985-02-19
Abstract: PURPOSE:To obtain an on-vehicle antenna without any projection part such as a whip antenna and offering good visual field for driving such as a glass antenna by utilizing a slope of a door biser of a cabin. CONSTITUTION:The door biser 4 consists of a horizontal part 43 and a slope 44 and a metallic part 41 is fitted to a door 2 as a side 42 and the rest is made of a non-metal. Then an antenna 5 is formed to the non-metallic part of the slope 44 and grounded by the metallic part 41. Since the metallic part 41 is stuck closely to a door frame 21, the part 41 is grounded through the car body. Then it is not required to draw a ground wire of the antenna 5 to the door 2.

Title: Bearing
Inventor: MATSUKAWA KIYOTAKA
IPC: C22F1/00
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To eliminate elements, such as lead highly toxic to the environment and human body, and to improve the conformability by including a specified ratios of tin and iron and copper for the balance, and connecting copper particles with tin. SOLUTION: Copper particles 1 and tin particles 2 are evenly mixed with each other with 1-10 wt.%, desirably 5 wt.% tin and the balance, copper. When the content of tin exceeds 10 wt.%, in a sintering process, the tin is separately melted to generate a flow-out hole and the characteristic as a bearing material is not satisfied. About 5 wt.% of tin content is desirable. Maximum 50 wt.% of iron can be added to the sintering material, as necessary. Namely, the abrasion resistance of the material can be improved by adding iron. When the content of iron exceeds 50 wt.%, a shaft to be borne by the bearing is worn by the iron, causing seizure. The content of iron is thereby desirably restricted less than 50 wt.%.

Title: Power source circuit for microcomputer
Inventor: FUJII MASAHIKO
IPC: G06F1/26
Filed: 1986-02-15
Abstract: PURPOSE:To prevent latch-up and malfunction by connecting a transistor, instead of connecting a diode between a supply node to the peripheral circuits of a microcomputer and that to the microcomputer main frame part. CONSTITUTION:In terms of a pnp transistor 16 connected between the supply nodes P and Q instead of a diode in a conventional power source circuit, its emitter and collector are connected to the supply nodes P and Q, respectively, and its base is grounded through a resistance R. Where load currents flowing in the supply nodes P and Q are the same value IL, the case where the transistor 16 is connected has a smaller drop in a voltage, which arises between the supply nodes P and Q, than the case where the diode is connected, as DELTAv and DELTAV show. Thus the destruction of a CMOS circuit and malfunction never occur.
