Title: Field effect transistor
Inventor: IWAMEJI KAZUAKI
IPC: H01L21/338
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce a misfit dislocation and a level difference in a silicon substrate, by forming a buffer layer on a V-groove made on one main surface of the silicon substrate and the one main surface thereof, an active layer and a gate electrode on the buffer layer, contact layers on both sides of the gate electrode, and source drain electrodes on the contact layers and the one main surface of the silicon substrate. SOLUTION: A V-groove G is made on one main surface of a silicon substrate 1 and a buffer layer 2 is formed from inside the groove G to the one main surface of the silicon substrate 1 to prevent the misfit dislocation of a semiconductor layer and a lattice constant. An active layer 3 shaped like a letter V in cross section is formed on the buffer layer 2, a gate electrode 5 is formed nearly at the center thereof, and contact layers 4 are formed on both sides thereof. Source drain electrodes are connected to the top ends of the contact layers 4. Since the top ends of the contact layers 4 are made flush with the top ends of the active layer 3 and the top surface of the buffer layer 2, the level difference of a device can be reduced.

Title: Motor-driven braking device for vehicle
Inventor: NIWA SATORU
IPC: F16D65/18
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To perform accurate control in various current control of an electric motor in a motor-driven braking device for a vehicle. SOLUTION: This braking device is provided with a pad disposed opposedly to a disc rotated integrally with a wheel, and an electric motor for pressing the pad to the disc through a driving member to apply braking force to the wheel. In the stop state of the electric motor, the driving current of the electric motor is gradually increased (step 222). In the gradually increased state of the driving current, the driving current at the time of the electric motor starting its rotating action is determined as the minimum driving current of the electric motor (step 214-220, 224). Even with the change of environment in which the braking device is placed, the minimum driving current corresponding to the environment is detected, and the electric motor is current-controlled using the minimum driving current, so that the current control can be performed always accurately.

Title: Method and device for developing photoresist
Inventor: OSAWA YASUSHI
IPC: G02F1/13
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for developing a photoresist wherein variation in resist pattern width is reduced. SOLUTION: The developing device comprises a chuck for sucking/fixing a substrate 2 where a photoresist 1 is formed, a developing liquid supplying device 4 comprising a high-temperature discharge part 11 for discharging a high-temperature developing liquid and a low-temperature discharge part 12 for discharging a low-temperature developing liquid, and a discharge control device 5 which controls the developing liquid supplying device 4 for its developing liquid discharge. With the substrate 2 sucked and fixed to the chuck 3, the developing liquid supplying device 4 is allocated above one side of the substrate 2 for only the high temperature discharge part 11 to discharge a developing liquid as the developing liquid supplying device 4 moves gradually.  When the developing liquid supplying device 4 moves near the center of the substrate 2, a discharge control device 5 stops the high temperature discharge part 11 from discharging, and instead allows the low-temperature discharge part 12 to discharge the developing liquid. In this condition, discharging of the developing liquid is performed up to side facing opposite the substrate.

Title: Method for machining slot in shaving cutter
Inventor: KANEKO TAKASHI
IPC: B23H9/00
Filed: 1985-11-28
Abstract: PURPOSE:To aim at carrying out an unmanned automatic machining process, by using a digit-like electrode having pitches corresponding to serration pitches. CONSTITUTION:A digit-like electrode 16 having pitches corresponding to the serration pitches of a shaving cutting 11 is attached to the front end of a machining head 15 attached to a column 14. This electrode 16 is fed into a tooth groove 17 in the shaving cutter 11, and therefore, several slots may be formed in a pair of opposing tooth surfaces 18, simultaneously. Thus, since an electric discharge phenomenon in which substantially no mechanical force is loaded during machining of slots is utilized, there are no troubles such as breakage of a tool or the like, and therefore it is not necessary that the operator sticks to the machining device, thereby it is possible to carry out an unmanned automatic machining process for the slots.

Title: Evaluating method for static memory
Inventor: KADOTA JUNJI
IPC: G11C29/00
Filed: 1988-10-21
Abstract: PURPOSE:To detect the distribution of a leak current due to the variance on production by providing a means which can electrically disconnect the current supply line through which electric charge is supplied to a memory cell. CONSTITUTION:When a fuse F1 is not disconnected yet, a P-channel MOSFET Q2 is turned on in a memory cell power supply circuit, and an external supply power level is supplied to the high resistance load of the memory cell through the FET Q2. When the fuse F1 is disconnected, the FET Q2 is turned off and the power supply line of the memory cell is electrically disconnected from an external power source and is set to the floating state. The data holding time of the memory cell after this disconnection of the power supply line is measured to indirectly lead out the leak current of the memory cell. In the same manner, data holding times of all memory cells are measured to individually measure leak currents in respective memory cells.

Title: Anti-howling device for loudspeaker
Inventor: OGAWA TSUKASA
IPC: H04R3/02
Filed: 1984-12-18
Abstract: PURPOSE:To minimize unnaturalness at the time of operation by checking only howling frequencies band when howling is generated. CONSTITUTION:In a howling phenomenon, vibration occurs in a narrow band inherent to an acoustic system. Accordingly, the sound made by synthesizing direct sound and the delayed 2 sound by a synthesizing circuit 3 becomes high in level by howling frequencies. When this is detected, the checked band of a band pass filter circuit 6 is adjusted to howling frequencies. The loudspeaked sound is made to that passed through the circuit 6. When howling is converged, said sound returned to normal whole band amplification. Consequently, unnaturalness at the time of operation is minimized.
