Abstract: PURPOSE:To improve the flatness still more in flattening methods after the first layer metalization wiring formation, by forming a pseudo inversion pattern of the first layer metallization wiring on a silicon oxide film containing impurities formed on a semiconductor substrate and further, forming the first layer metalization wiring after forming a contact window. CONSTITUTION:A silicon oxide film 21 containing impurities is formed on a semiconductor substrate 10 and a pseudo inversion pattern 22 of the first layer metalization wiring is formed on the above film 21 and further, the first layer metalization wiring 28 is formed on the above film 21 after forming a contact window. For example, after depositing a BPSG film 21 of 1.5mum thickness on the semiconductor substrate 10 where a source 11, a gate 12, and a drain 13 are formed, the surface is flattened by treating with heat. Then, after patterning it with a resist 51, the BPSG film 21 is etched to the depth of 0.8mum to form the pseudo inversion pattern 22 of the first layer metalization wiring. Then, after forming the contact window by patterning with the resist 52, a metallic film is deposited to a depth of 0.8mum and then, the first layer metalization wiring 28 is formed by etching after patterning with the resist 53.

Inventor: NAKAMURA KENICHIRO
IPC: F16H53/06
Filed: 1994-12-20
Abstract: PURPOSE: To provide a structure which supports a roller-like cam follower which is in contact with a drive cam on a pair of support plates which are apart and erected in parallel. CONSTITUTION: A support structure of a roller-like cam follower 52 has a configuration in which a follower support shaft 56 is press-fitted into the rollerlike cam follower and both ends of the support shaft are supported by needle bearings 57, 57 provided on a pair of support plates 58, 58. The rollerlike cam follower 52 is supported by the needle bearings integrally with the press-fitted follower support shaft while it is in contact with a drive cam and rotate for the pair of support plates 58. Since the rollerlike cam follower is press-fitted into the follower support shaft, the whole inner periphery of the rollerlike cam follower adheres on outer periphery of the follower support shaft.  Accordingly, it is possible to increase outside diameter of the follower support shaft without changing outside diameter of the rollerlike cam follower to increase load strength in the radial direction, and there is no possibility that eccentric friction is generated on outer periphery surface of the follower support shaft because both rotate integrally.

Title: Molding method of disk base plate
Inventor: YOKOTA SHOJI
IPC: B29C45/80
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To largely restrain generation of irregular releasing such as pit deviation and double transfer at the time of formation of a base plate so as to obtain a bake plate for optical disk having no molding defect by lowering a sucking pressure for sucking and holding a stamper during induction of a resin and heightening it during opening of a mold. SOLUTION: After a mold is closed, a melting resin is induced in a mold cavity 10'. At this time, a sucking force for sucking a stamper 2 is preferably extremely low. A sucking force is 40 KP or lower per unit area (1m<2> ), and a sucking force of 30 KP or lower is preferable. When the force for sucking and fixing the stamper 2 is too weak at the time of mold opening, the stamper 2 is peeled from the mold together with a resin base plate so as to be in a floating state, resulting in pit deviation. At the time of mold opening, the stamper is to be sucked strongly. In this case, fixing with a sucking force of 50KP or higher per unit area is preferable. It is 400mmHg or above in degree of vacuum.

Inventor: TAKANO YOICHI
IPC: B29C67/00
Filed: 1988-12-28
Abstract: PURPOSE:To accelerate the forming speed of a cubic shape and, at the same time, form the accurate cubic shape by lowering the viscosity of resin material through the controlling of the temperature of the liquid resin material by a structure wherein a housing vessel having a conductor section, a high frequency heating coil arranged in the conductor section and liquid temperature sensor to measure the temperature of liquid photo-setting type resin material are equipped. CONSTITUTION:When the excess of the temperature of liquid photo-setting type resin material 3 at its surface 3a over the lower limit of the arbitrarily set temperature range after the supply of high frequency current to a high frequency heating coil 4 is detected with a liquid temperature sensor 5, a signal is outputted from a temperature controller 7 to a controlling section 27 so as to perform the raster scanning by exposure beam 21 to the region corresponding to the stage 6 of the surface 3a of the liquid photo-setting type resin material 3. Said raster scanning is done with respect to the respective partition planes of a cubic shape. Thus, when the raster scanning by the exposure beam 21 to the surface 3a of the liquid photo-setting type resin material 3 with respect to one partition plane comes to an end, the scanned region sets, resulting in producing a set resin layer, which has the same shape as that of a partition plane to be produced for the first time.

IPC: B60K20/02
Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To solve the problem of the conventional failure detecting method for a shift knob device for an M/T automatic clutch, in which it is monitored whether switch signals output from the shift knob device are all on or not, and when all are on, a failure is determined, which can not be applied to a shift knob device of a new type in which in the case of a neutral position, switch signals are all on. SOLUTION: In a shift knob device of a new type, all of output signals are on in the case of a neutral position, and in the case of forward tilting or backward tilting caused by shift operation, one output signal is on and the other output signal is off. That is, in the normal case, signals do not become all off. If all off signals are output, it is nothing but a failure. A controller for conducting the control operation on receiving a signal from the shift knob device is provided with a totally cutoff failure detecting part 3-2 for monitoring whether signal are all off or not, thereby making a failure detection.
