Title: Driven wheel or transporting car
Inventor: SUZUKI NOBUSHI
IPC: B60B33/00
Filed: 1985-03-01
Abstract: PURPOSE:To prevent slippage between a wheel and a running surface when changing the direction of running, and improve a load withstanding performance by providing plural wheels each independently rotatably on a wheel shaft which is inclinedly provided on a supporting shaft which is perpendicular to said running surface. CONSTITUTION:A hollow and conical wheel 25 and a small wheel 26 which is housed in the wheel 25, are independently rotatably installed on a wheel shaft 23 which is inclinedly provided at a certain angle to a supporting shaft 15 having an axis perpendicular to a running surface L. By this construction, difference between the rotating direction of the supporting shaft 15 and the rotating direction of the wheels 25, 26 centering around the wheel shaft 23 when a vehicle body 11 changes its direction, can be made smaller than when the wheel shaft 23 is horizontally provided, preventing the slippage of the wheels 25, 26, deviation from the track of the vehicle body 11, and the generation of dust due to the wear of wheels, and enabling the use of a carrying vehicle in a clean room.

Title: Brake control system for car
Inventor: TAKAGI KENICHIRO
IPC: B60T8/26
Filed: 1985-03-01
Abstract: PURPOSE:To prevent the delay of brake application even if antiskid control is erroneously started, by detecting the car height and correcting the pressure increasing characteristic in pressure increasing control to the sharp pressure increasing characteristic, when the car height variation within a prescribed time becomes over a predetermined certain amount of variation. CONSTITUTION:A car-height detecting circuit 151 calculates car height Hv on the basis of the output signal of a car-height sensor 150. A car-height variation detection circuit 200 outputs a detection signal when the variation within a prescribed cycle of the detected height outputted from the car-height detection circuit 151 becomes over a certain value delta, and a pressure increasing characteristic correcting means corrects the gentle pressure increasing control characteristic in skid control to the sharp pressure increasing characteristic, and after the variation of the detected state becomes over a certain value, the brake hydraulic system is controlled by the sharp pressure increasing characteristic.

IPC: H01L21/302
Filed: 1983-03-14
Abstract: PURPOSE:To enable to perform an etching on a conductive thin film only without etching an iusulating thin film by a method wherein a conductive substrate on which a conductive thin film is provided through the intermediary of an insulator is placed on the cathode of an electrode through the intermediary of an insulator. CONSTITUTION:Reaction gas is introduced into a reaction chamber 6 by a reaction gas introducing device 8, plasma 18 is generated when a DC current is applied between an anode 9 and a cathode 10, and radical 21 arrives at a sample 16. However, a gate oxide film 2 is formed on the sample 16, and when a Teflon sheet 17 is provided between the cathode and the substrate 1 of the sample 16, the charge of the arrived ion 20 is accumulated until the potential gradient of the cathod drop part 19 is removed, and from that time only the radical 21 alone comes in. On the other hand, the polycrystalline Si film 3 reaches on both ion 20 and the radical 21, but a film 2 reacts on the ion 20 only. Accordingly, no etching is performed on the film 2. As a result, when an etching is performed on the film 3 again after a part of the film 2 has been exposed, the film 2 is not etched.

Title: Non-volatile semiconductor memory
Inventor: TAKANO HIROSHI
IPC: G11C16/04
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To store multi-valued data in a memory cell, and to ensure a sufficient margin in the write operation and read operation of the multi-valued data. SOLUTION: A plurality of data values (11), (10) are accommodated regarding a region, in which a cell current value Id is not altered to the change of floating-gate potential Vfg. When the low-order one bit of read data is read in a read mode, the potential of bit lines BLm-BLp is increased or lowered in accordance with the data value of a high-order one bit. Consequently, a Vfg-Id characteristic curve is shifted to the positive side or the negative side, and a point, where the data value of the low-order one bit of the read data is changed over, is conformed at a point B at the same potential as threshold voltage Vth. Accordingly, the data value of the low-order one bit of the read data can be identified depending upon whether the cell current value Id occurs.

Title: Crushing apparatus
Inventor: FUJIWARA TAKASHI
IPC: B02C18/22
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To efficiently crush ever recovered raw materials of waste plastics to which foreign substances adhere without depositing the foreign substances to crushed matter. SOLUTION: An air-tight chamber 16 partitioned from a crushing chamber 13 is installed at a sieve 14 in a crushed matter discharge outlet 15 of a crusher in which a raw material is thrown through a throwing inlet 11 to the crushing chamber having an operating cutter 12 and the crushed matter is discharged through the sieve 14 laid in the crushing chamber 13. A blower 17 is installed in the air-tight chamber 16 to lower the inside pressure more than that in the throwing inlet 11. When raw materials of collected refuse are thrown together with water, the crushed matter mixed with water is sucked due to the pressure difference between the air-tight chamber 16 and the throwing inlet 11 and is forcibly passed through the sieve 14. Consequently, clogging of the sieve 14 and inverse flow or overflow to the throwing inlet 11 do not occur.  Moreover, the crushed matter is prevented from stagnating in the crushing chamber for a long and from being unnecessarily crushed fine. Even in the case foreign substances adhere to the raw materials of collected refuse, the crushed matter 36 with even particle diameter and free from deposition of foreign substances can be obtained.

IPC: G11B19/02
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To keep the minimum levitation amount of a head large without sacrifying the seek time. SOLUTION: A head-positioning control circuit 8 is installed in such a way that, in a seek operation in which a head 1 held by a rotary actuator 2 is moved to a target cylinder, and it judges whether its seek direction is a first direction toward the outer circumference from the inner circumference of a disk or a second direction toward the inner circumference from the outer circumference, and it finds a seek maximum speed in a head position on the basis of the seek direction and the head position. Then, the control circuit is constituted in such a way that, in a seek in the first direction, a comparatively slow head maximum speed Vmax 1 is used on the inner circumferenctial side on which a head levitation amount is dropped largely and that it is changed over to a speed Vmax 2 which is faster that the speed in a halfway part.

Title: Fuel control device for internal combustion engine
Inventor: KOBAYASHI YOSHIYUKI
IPC: F02D41/14
Filed: 1989-02-21
Abstract: PURPOSE:To prevent the aggravation of the exhaust gas value at a starting time by performing the feedback control of fuel so as to obtain a specified air-fuel ratio by a partial control constant for a specified time from the shifting time when an internal combustion engine is shifted from the idle operating region to the partial operating region at the time of the car speed being zero. CONSTITUTION:At the time of idle operation, the stabilization of idle engine speed is promoted by performing fuel injection control slowly by an idle control constant small in amplitude and large in cycle. When the shifting from the idle operating region to the partial operating region is judged from the signal of an idle switch 46 at the time of detecting the car speed being zero in a control part 28 by a speed sensor 42, the fuel is feedback controlled to have the specified air-fuel ratio by a partial control constant large in amplitude and small in cycle for the specified time from the shifting time. After the lapse of the specified time, the fuel is feedback controlled by a smaller control constant on the idle control constant side than the partial control constant.
