Title: Method for reforming surface of warm and hot member
Inventor: CHIBA YOSHITAKA
IPC: C23C8/28
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To improve the sliding characteristic or corrosion resistance in nitrosulfurizing as a combination of nitriding, sulfiding and oxidizing by using a mixture of the colorless ammonium sulfide soln. and yellow ammonium sulfide soln. as a sulfide source. SOLUTION: A reforming gas generated from a mixture of the colorless ammonium sulfide soln. and yellow ammonium sulfide soln. and gaseous ammonia is introduced onto the surface of a warm and hot member to form a reformed layer enriched with sulfur and nitrogen on the member as oxygen. The colorless ammonium sulfide soln. and yellow ammonium sulfide having a different sulfur content are mixed to obtain a reforming gas having a higher content of H2 S than in the case when only the colorless ammonium sulfide soln. is used. Consequently, dense nitriding and oxidizing are allowed to proceed at the same time by the action of the high H2 S concn. and the NH4 OH relatively lowered in concn. or H2 O while supplying the excessive formation of the oxide with surface being porous.

Title: Error detection circuit for o-qdpsk modulation wave
Inventor: MURABAYASHI NOBORU
IPC: H04L27/18
Filed: 1991-03-05
Abstract: PURPOSE:To improve an error correction capability by discriminating data to be error data when a succeeding set of data of each data set of an offset QDPSK modulation wave is data unable to be an offset QDPSK modulation wave. CONSTITUTION:A signal fed from an amplifier 62 is fed to an 0-QDPSK demodulation circuit 71. The circuit 71 demodulates the signal synchronously with a carrier recovered by a carrier recovery circuit 72 and inputs a demodulation signal to a digital signal processing circuit 74. On the other hand, an error detection circuit 73 discriminates directly an error from an 0-QDPSK signal. In this discrimination, since a phase of a data series D1 of an 0-QDPSK modulation wave changes in a range of -pi/2 to +pi/2 with respect to a data series D0 just before the series D1, the phase is not chanted by -pi or +pi between the consecutive data series D0 and D1. Thus, the circuit 73 judges a succeeding data series being the data not in existence to be in error and gives error detection information to the circuit 74. Through the constitution above, the error correction capability is improved.

Abstract: PURPOSE:To prevent damage due to the freezing of remaining water by arranging a water supply tank outside the cabin of an automobile, and a motor water supply pump in a position higher than the water supply tank in the cabin to eliminate the remaining water at the time of the stamp water supply pump. CONSTITUTION:A water supply tank 3 and a water supply pump 4 are provided on the lower surface of the floor plate 1' of a part 1a outside the cabin of an electric automobile 1 and on a position higher than the tank 3 on the floor plate 1' of a part 1b in the cabin respectively. When a level sensor in a storage battery 2 detects the reduction of battery liquid, the pump 4 is automatically driven to supply water to the collective water supply device 2a of the first storage battery unit 2' from the tank 3. The supply water in the device 2a is supplied to the unit 2' to a given level liquid surface, and then passes a pipe 5a to be supplied to the next unit 2' to a given level liquid surface similarly via the device 2a. When this water supply is completed, remaining water passes the pipe 5 to be returned to the tank 3 to automatically stop the pump 4. Consequently, the remaining water in the pump 4 can hardly be left to prevent damage due to the freezing of the remaining water.

Abstract: PURPOSE:To decide the optimum command overrun time point, and to aim at the effective utilization of a magnetic tape, and the appropriateness of a write time, by constituting a device so that the traveling of the magnetic tape is stopped based on a specified condition. CONSTITUTION:When a write timing is not able to follow the traveling speed of a magnetic tape 6 in the device which is driven based on a streaming operation system, the device is constituted so that the traveling of the magnetic tape 6 is stopped based on the read/write gap dH of a magnetic head 5, and the minimum length regulated by the response time of a magnetic tape driving system. Also, the magnetic tape 6 travels in arrow head A direction in figure, and an ordinary inter block gap (IBG) is provided between data blocks DB1 and DB2. The length of the IBG is made shorter than the read/write head gap dH. In this way, when the command overrun is generated, it is no necessary to perform a reposition operation, and also, the IBG of the magnetic tape 6 can be set at the optimum length.

IPC: E02D5/80
Filed: 1994-03-10
Abstract: PURPOSE:To average and disperse the stress generated in an anchor body by adjoining and mixing a tension type fixing section and a compression type fixing section into a composite fixing section. CONSTITUTION:Deformed bars 5 are inserted into tension type holes 8 among many holes bored on a bearing plate 2, terminals of mottle unbound steel strands 4B are fixed to other compression type holes 7, and load bearing bodies 3 are fixed to the bearing plate 2 to cover their peripheries.

Title: Semiconductor dicing method
Inventor: OKI TETSUO
IPC: H01L21/301
Filed: 1993-03-01
Abstract: PURPOSE:To prevent silver which has been once cut at the part of thick plating without a remarkable decrease of production, from being again fused by the heat at the time of cutting. CONSTITUTION:The feed speed of a blade 1 is set as follows; cutting is started from the one end L at a moving speed of 16mm/s, the speed is gradually increased, a semiconductor wafer 2 from a specified position L to a specified position L is cut at a speed of 40mm/s, the speed is gradually decreased from the specified position L, and the cutting is finished at the other end L of the semiconductor wafer 2, when the moving speed is 16mm/s. That is, the cutting speed is gradually increased at the beginning of cutting, and gradually decreased at the ending of cutting, so that the part of thick silver plating is slowly cut and the heat generated by cutting is sufficiently cooled by using cooling water. Thereby the silver-plated part can be prevented from fusing again, and the generation ratio of half-cut caused by that the silver-plated part again fuses is reduced from about 9% to about 0.55%.
