IPC: H01M8/06
Filed: 1985-09-17
Abstract: PURPOSE:To prevent the scattering of a catalyst of powder from the catalyst filling layer sealed within a reforming tube within a reformer and the inflow of said catalist into shift converter with the reformed gas by providing a separator between the reformer and the shift converter. CONSTITUTION:A separator 28a which separates gas from powder material existing together is provided between a reforming device 6 and a shift converter 10. A reforming gas is supplied to this separator 28a through a conduit 27 and a powder material separated therein, namely a catalyst of powder is collected at a stocker 29 provided at the lower part. Such catalyst powder is then sent again to the reformer 6 for use through a conduit 30. Meanwhile, the reforming gas separating the catalyst is supplied to the shift converter 10 through the conduit 11. Thereby, it may be prevented that the catalyst powder is scattered from a catalyst filling layer 9 sealed within the reforming tube 7 within the reformer 6 and it flows into the shift converter 10 together with the reforming gas.

Title: Method for preventing additional heating to higher temperature in hot-water system for bathtub
Inventor: OCHI MIKIO
IPC: F24H1/00
Filed: 1990-07-31
Abstract: PURPOSE:To prevent bathwater from being heated to excessively high temperatures by a method wherein an additional-heating sensor detects the temperature of hot water for bath in a heat exchanger while a bath sensor detects the temperature of the bathwater in a bathtub and, when the difference between the temperatures detected by the two sensors exceeds a specified point, the combustion at the burner is turned off.

Title: Inter-gauge mark displacement gauge
Inventor: TSUJI OSAMU
IPC: G01N3/06
Filed: 1984-09-29
Abstract: PURPOSE:To detect displacement between gauge marks of a test piece accurately, by applying a test load to a test piece with a pair of load rods arranged on the coaxial line. CONSTITUTION:A pair of detection rods 14A and 14B are arranged parallel with load rods 1A and 1B and supported entirely with a plurality of plate springs 15-17 in such a manner as to be movable axially. One hand ends of the detection rods are pressed on a test piece 2 with coil springs 20A and 20B while a detector such as differential transformer 7 is provided at the other hand ends thereof. Then, when a load mechanism is driven, a test load is applied to the test piece 2 with the load rods 1A and 1B and the load of the test piece 2 is detected with a load cell 12. When a displacement is caused between gauge marks of the test piece 2, the bent ends of the detection rods 14A and 14B are pressed on the test piece 2 with coil springs 20A and 20B to follow it 2. The plate springs 15-17 deflect axially to the detection rods 14A and 14B to absorb the axial movement thereof. Thus, a coil 8 and a core 9 of the differential transformer 7 displace relatively thereby allowing the detection of displacement between gauge marks of the test piece 2.

Title: Semiconductor device
Inventor: KATO JURI
IPC: H01L21/322
Filed: 1988-08-18
Abstract: PURPOSE:To obtain a highly reliable semiconductor device consisting of a diffusion layer which causes a low leak of electricity but has a high breakdown strength even though its diffusion layer has a shallow junction of 0.1mum or less deep by causing the diffusion layer to be composed of the Si layers which contain the secondary defects due to ion implantation damage and perform epitaxial growths selectively as well as an Si substrate layer having a denuded zone. CONSTITUTION:After forming element isolation insulating films 2, gate sidewall insulating films 5, a gate film 3, and a gate electrode 4 on an Si substrate 1, Si layers 6 performs selectively epitaxial growth of 0.15mum on the surface of the Si substrate 1. After that, ion implantation of As makes upper layers of about 0.08mum thickness in the Si layers 6 amorphous and allows As to be distributed up to the depth of about 0.05mum in the substrate. Then, for example, secondary defects 7 develop on an amorphous/single crystal interface by treating with heat in 10 seconds at a temperature of 1000 deg.C. If heat treatment is performed for 10 minutes at a temperature of 900 deg.C, the secondary defects 7 in the Si layers 6 grow to absorb the defects at interfaces 9 between the Si layers 6 and the substrate; further, gettering of heavy metals and the like is performed. As a result, no contaminated substance exists at the Si layers 6 and the interfaces 9 in the vicinity of junction faces 10 of source and drain regions. A leakage current thus decreases even at the source and drain regions 8 having depths of 0.1mum or less in the Si substrate.

Abstract: PURPOSE: To prevent generation of torque shock by stabilizing combustion in the idle operation through a process of prohibiting only switching from a low speed cam to a high speed cam regardless of the operating condition when the oil temperature is the set temperature or less. CONSTITUTION: A control unit controls the switching between cams 10, 11. When the oil temperature is lowered and becomes the specific temperature or less caused by traveling on the long downhill, the actually used cams 10, 11 are judged.

If the high-speed type cam 11 is used, the operating condition is judged, and the cams 10, 11 are selected and switched according to the condition. That is, the low speed cams 10 are selected in the low speed range having the specific rotational number or less, and the high speed cam 11 is selected in the high speed range having the specific rotational number or more.  When the oil temperature is the specific temperature or less, only the switching from the high speed cam 11 to the low speed cams 10 is allowed, and the switching from the low speed cam 10 to the high speed cam 11 is prohibited until the temperature rerises.
