Title: Two-phase motor drive
Inventor: TAKEMORI AKIO
IPC: H02P27/06
Filed: 1992-10-13
Abstract: PURPOSE:To provide a driver for driving a two-phase motor at a variable speed by generating an AC voltage having variable frequency through an inverter for modulating a DC voltage with an arbitrary AC voltage in which even a two-phase motor comprising main and auxiliary widings having different number of turns can be operated smoothly while reducing torque ripple by forming a circular rotating field through the windings of both phases. CONSTITUTION:An inverter 3 comprises first and second power controllers being controlled independently and turn ratio is calculated based on measurements of voltages induced, respectively, in the main winding 4-1 and an auxiliary winding 4-2 of a two-phase motor 4 through preliminary rotation. Ratio of output voltages from the first and second power converters are then controlled in proportion to the turn ratio thus calculated.

Title: Method and device for recording and reproducing frame of video tape
Inventor: SATO KOICHI
IPC: G11B15/467
Filed: 1985-12-28
Abstract: PURPOSE:To make such an operation unnecessary that for recording a frame a control signal is previously recorded on an overall magnetic tape by simultaneously recording control signals for frame feed at the prescribed interval in terms of frame feed. CONSTITUTION:In a recording mode, the 1st control signal reproducing head 24 reproduces the control signal recorded by a control signal recording head 22. The reproduced control signal energizes the head 22 to record the control signal. Then the control signal reproduced by the 2nd control signal reproducing head 26 stops the travel of the magnetic tape 10. On the other hand, at the time of reproducing a frame the control signal recording head 22 is inhibited from recording the control signal, and the control signal reproduced by the 2nd control signal reproducing head 26 stops the travel of the magnetic tape 10. Namely, at the time of recording a frame, frame feed control signals are simultaneously recorded at the prescribed interval l1.

Title: Roller type sifting device
Inventor: KOIDE HIROSHI
IPC: B07B1/14
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent a material to be treated from being caught between rollers and from being reversely rotated to clog the roller clearance. SOLUTION: Large diameter rollers 12 and small diameter rollers 13 are alternately arranged. The surface height of the small diameter roller 13 is made lower than that of the large diameter roller 12 one away on the upstream side.

Title: Manufacture of semiconductor device
Inventor: MIYASATO TATSUYA
IPC: H01L21/302
Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To prevent a deposit from peeling resulting in a defective pattern at anisotropical dry etching of a film exposed at the ends by etching it after masking the ends thereof. SOLUTION: A second polysilicon film 9 is masked up to its ends 9a with a resist 16 and anisotropically etched to leave a second polysilicon pattern 17 on the ends of PROM regions 3. At the anisotropical etching, no deposit appears on the ends because of the ends 9a masked with the resist 16. Hence the deposit will not peel or float to deposit to another pattern and never mask anything at later dry etching steps. Thus this means prevents defective finished patterns.

Abstract: PROBLEM TO BE SOLVED: To improve dampproofing property by covering between a low-pressure sodium lamp and a lamp socket with a packing, and to stop electrical discharge by rapidly introducing outer air into a tube body to fuse a lead, when an electrode is damaged. SOLUTION: A front socket packing 41 liquid-tightly covers between a low- pressure sodium lamp L and a lamp socket 8. A slit to be an air valve is formed in the front socket packing 41. The slit is usually closed in a liquid-tight manner. When an electrode 14 is damaged and an outer tube 12 whose inside is vacuum is damaged, the packing 41 is deformed by negative pressure and the slit is deformed, so that outer air is introduced into the inside of the outer tube 12. The outer air quickly fuses a lead 26 which acts as a fuse, to stop electrical discharge.
