Title: Inverter
Inventor: NAGAI KAZUNOBU
IPC: H02P6/16
Filed: 1992-09-11
Abstract: PURPOSE:To avoid the decline of a motor efficiency caused by the delay of the rise of a winding current from a commutation timing in an inverter which facilitates that, in order to drive a brushless motor with PWM(pulse width modulation) control, the rotor rotating position of the motor is recognized by waveform synthesis from the terminal voltage of the motor winding and a recognition waveform having commutation timing information is formed and the commutation timing of the winding is obtained in accordance with the recognition waveform. CONSTITUTION:A current applied to a three-phase bridge circuit 13 is detected by a shunt resistor 32. A time corresponding to an electrical angle of 30 degrees from the rise time of a recognition waveform is used as a reference timing. The reference timing is corrected so as to have a detected current minimum and the commutation timing of a motor winding is determined.

Title: Semiconductor manufacturing device and manufacture of semiconductor device
Inventor: FUTASE TAKUYA
IPC: H01L21/205
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To improve evenness in film thickness of a wafer surface without using a special wafer support jig. SOLUTION: The gas flow speed v(r) in Z-axis direction is increases by increasing a gas flow rate or reducing an interval a-b between a wafer 3 and an inner tube 2. The v(r) has a speed gradient in r-direction, causing a pressure difference in the r-direction based on Bernoulli's theorem. The pressure difference moves a reactive gas in the r-direction, causing a concentration gradient by -dC/dR in the r-direction. The reactive gas sticking to the peripheral part of the wafer 3 before deposition is moved in the r-direction to decrease the gas concentration at the peripheral part of decreasing deposition film thickness at the wafer's peripheral part and improving the evenness in film thickness. Related to the gas flow rate, a pressure difference ΔP in z-direction is 1Pa/mol or above, while 4Pa/mol or above is preferred.  The interval a-b is 40 mm or less while 20 mm or less is preferred.

IPC: C07C51/50
Filed: 1993-09-30
Abstract: PURPOSE: To provide the composition for storing and using acetic acid or propionic acid which acid is linked with a substrate so that the acid is able to dissociate. The composition has been prepared by incorporating an aliphatic acid into an alkaline(earth) metal salt of acetic acid or propionic acid.  
     CONSTITUTION: The composition is comprised of an alkali (alkaline earth) metal salt of acetic acid or propionic acid and an aliphatic carboxylic acid(e.g. trans fumaric acid) which has a pKa value lower than that of acetic acid or propionic acid, respectively. When this composition is brought into contact with a solvent system (e.g. water) capable of allowing ionization of the salt and the aliphatic carboxylic acid, free acetic acid or propionic acid is released in situ. The method enables the free acids to be stored and released at the point of use, thereby substantially reducing the risks of corrosion and unpleasant odors.

Title: Magnetic head for vertical magnetic recording and reproducing
Inventor: YAMAURA SATORU
IPC: G11B5/127
Filed: 1984-11-21
Abstract: PURPOSE:To make a magnetic head small-sized and light-weight by providing a pair of an auxiliary magnetic pole arranged in the outside edge part of a magnetic recording medium and a main magnetic pole which can be moved along the surface of the magnetic recording medium. CONSTITUTION:When a write current is flowed to a coil 7, an auxiliary magnetic pole 2 is magnetized, and its magnetic field is concentrated to a main magnetic pole 1 by a high permeability layer 5. Consequently, residual magnetization in the direction perpendicular to the surface of a recording medium 3 occurs in a magnetic recording thin film 6 just under the main magnetic pole 1 even after the write current to the coil 7 is broken, and it is recorded as information. When the magnetic field of the auxiliary magnetic pole 2 is inverted in accordance with the direction of the write current, magnetization of the main magnetic pole 1 is inverted, and the direction of residual magnetization of the magnetic recording thin film 6 is inverted. Thus, the recording medium 3 is rotated and residual magnetization is inverted in case of reproducing of recorded information to obtain reproduced information as a voltage signal generated by the coil 7.
