Title: Semiconductor manufacturing process to control trench depth uniformly
Inventor: GO CHOSHAKU
IPC: H01L21/3065
Filed: 1999-12-16
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor manufacturing process to control trench depths uniformly. SOLUTION: A substrate is provided to form a first dielectric film thereon, which is then overlaid with an etching stop film and a second dielectric film in this order. Next, the second dielectric film is patterned to form a trench in the second dielectric film, thereby exposing the etching stop film. A material having a high etching selective ratio to the second dielectric film is used as an etching stop film to stop the etching step for patterning the second dielectric film with the etching stop film, so that formed trenches have a more uniform depth.

Title: Preheating method for member and coating device
Inventor: BURNS STEVEN M
IPC: C23C14/02
Filed: 1998-12-17
Abstract: PROBLEM TO BE SOLVED: To reduce and control the forming rate of an oxide layer (thermally grown oxide, TGO) and the final thickness of the TGO and to satisfactorily stick a top coat to a member. SOLUTION: This is a method for reducing the formation of surface oxide in preheating treatment for a member having a face contg. aluminum in a vacuum atmosphere executed before the application of ceramic coating. In this method, by injecting an inert gas or a nonreactive gas into the vicinity of the member to be applied with coating in a coating device in the process of the preheating, the oxidation of the member is reduced. For the injection of the gas, a housing device or a nozzle device partially surrounding the member is used.

Title: Crimp terminal
Inventor: AOYAMA MASAHIKO
IPC: H01R4/24
Filed: 1999-12-17
Abstract: PROBLEM TO BE SOLVED: To reduce crimp resistance in a V-shaped pressure blade. SOLUTION: Since inclination angle α, β of edges 21 of two blades 19 formed in the shape of a V, seen from the axial direction of an electrical wire 16 are different, the timings of the edges 21 contacting a resin coat 16A when the electrical wire 16 is pressed in are different. Therefore, the resin coat 16A is incised not with both blades 19 contacting the resin coat 16A at the same time but with one of the blades 19 first contacting the coat as a single blade. As a result, only small resistance is applied in incising the coat.

Title: Signal estimating device and storage medium for storing program
Inventor: MATSUI HITOSHI
IPC: H04L27/14
Filed: 1998-12-17
Abstract: PROBLEM TO BE SOLVED: To highly precisely and quickly operate a phase synchronizing loop circuit for correcting phase change due to frequency offset or the like in a system for applying signal estimation to a received signal which is largely affected by signal path distortion by using a DDFSE or an MLSE(maximum likelihood system estimator). SOLUTION: A received signal which is affected by signal path distortion is phase-rotated by a phase rotator 102, and signal estimation is operated by an MLSE 103. Also, a phase difference between the information of the minimum path metric in the viterbi algorithm of the MLSE and a signal obtained by delaying the phase-rotated signal is detected by a phase detector 105, and this phase difference signal is filter-processed and inputted to a VCO 107, and the phase rotation is controlled according to the VCO output. Thus, the delay time of the information of the minimum path metric is small so that high speed and highly precise signal estimation can be attained even when frequency offset is added to the received signal.

Title: Window regulator of automobile
Inventor: HASHIBA YASUHIRO
IPC: E05F11/44
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To improve waterproof/dustproof performance by arranging a prescribed member such as a motor on the cabin side of an inner panel, and arranging the other member outside the inner panel. SOLUTION: A motor 15 of a window regulator 7 to raise/lower window glass 6, a pinion 16, a gear 18 and a meshing part of the pinion 16 and the gear 18, are not arranged in a space S between an inner panel 5 and an outer panel 4 as usual, but are arranged on the cabin inside more than the panel 5. In this case, the gear 18 can be arranged on the cabin inside more than the space S by fixing a lift arm 20 and the gear 18 through a connecting piece 22 passing through a hole 14 formed in the panel 5. Therefore, even if rainwater and dust/dirt infiltrate from an upper opening 30 of the space S, they do not enter the motor 15, the pinion 16 and the meshing part of the pinion 16 and the gear 18.  Therefore, a cost can be reduced since waterproof processing is not required for the motor and an Eleatrical part, and the service life can also be lengthened since early abrasion of the meshing part of the pinion and the gear is prevented.

Title: Method for detecting water in hot-water supplier
Inventor: IKEZAWA TAKASHI
IPC: F24H1/10
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To provide a method by which the presence/absence of water in a hot-water supplier can be detected surely by using a thermistor. SOLUTION: When water presence/absence discriminating work is started at time t1, the power supply voltage to a thermistor is raised to a high voltage VH for water detection from an ordinary low voltage VL for temperature detection and, when the thermistor reaches a high temperature by self-heat generation at time t2, the power supply voltage is switched to the low voltage VL. When water is present in a hot-water supplier, the thermistor does not become warm and the resistance value of the thermistor is high as shown by the curve I even when the high voltage VH is applied.  Therefore, the voltage Vt generated across both terminals of the thermistor becomes higher (curve I) when the water is present than the case where water is absent (curve II), because the resistance value dropping of the thermistor caused by temperature is smaller than the case where water is absent as shown by the curve II.
