Inventor: IWAI HIROSHI
IPC: H01L21/336
Filed: 1990-01-11
Abstract: PURPOSE:To reduce a cost by forming the semiconductor part of a thin film transistor on a gate-bus electrode and making a drain electrode a diffused reflection electrode constituted of aluminum which is vapor-deposited under a low vacuum state. CONSTITUTION:A switching element having thin film transistor structure is formed smaller than the width of the gate electrode on the upper part of the bus wiring of the gate electrode 23 and the drain electrode 25 of the thin film transistor has high reflectance and has the constitution of a picture element electrode made of conductive material whose diffusion efficiency of light is high. Therefore, producing stages are simplified at least by four stages as compared with a conventional reflection type liquid crystal display device and the number of masks is decreased by two.

Title: Semiconductor device and manufacture thereof
Inventor: OBA NOBUKAZU
IPC: H01L23/52
Filed: 1995-01-17
Abstract: PURPOSE: To prevent generation of cracks in a protective film in the case that a PSG film as the protective film is formed on an Al wiring. CONSTITUTION: When a PSG film 4a and a nitride film 4b are deposited on an Al wiring 3 of a semiconductor element, phosphoric acid generated by moisture taken into the PSG film 4a causes corrosion between the PSG film 4a and the Al wiring 3, and a gas generated by the corrosion generates cracks in the protective film 4. However, by forming an oxide film 5 between the Al wiring 3 and the PSG film 4a, such corrosion and hence generation of cracks in the protective film 4 can be prevented.

Title: Magnetic disk device
Inventor: HAMADA TAIZO
IPC: G11B17/34
Filed: 1988-01-14
Abstract: PURPOSE:To set at a necessary minimum value to obtain a stable contact between a magnetic disk and a magnetic head by constantly keeping a constant contacting force between the magnetic disk and the magnetic head regardless of the position of the magnetic head. CONSTITUTION:When a magnetic head 20 is located in the vicinity of the outer circumferential part of a magnetic disk 1, since a height Zp of the regulation ends 14a and 14b of a disk regulation piece 14 is low, the bending deformation quantity Bd of the magnetic disk 1 is large, since the height Zp at a section containing the magnetic head 20 is gradually higher as approaching to the vicinity of an inner circumferential part, the bending deformation quantity Bd of the magnetic disk 1 is gradually smaller. A flexural rigidity Yd of the magnetic disk 1 is smaller in the outer circumference and larger in the inner circumference. Consequently, since the flexural rigidity Yd of the magnetic disk, namely a contacting force P between the magnetic disk 1 and the magnetic head 20, is proportionate to Yd and Bd, turns to approximately constant. Thus, when the necessary minimum contacting force P by which the magnetic disk 1 and the magnetic head 20 turn to be a stable and close condition, the necessary minimum contacting force P can be obtained even when the magnetic head 20 is located at any position.

IPC: D03D1/02
Filed: 1995-01-18
Abstract: PURPOSE: To produce a woven fabric of high quality for industrial purpose, which is excellent in tensile strength, tearing strength and flexibility and can easily be designed so that these properties may become almost equal in both warp and weft directions, thus has such a high isotropy that the fabric can be handled equally in both warp and weft directions on cutting and sewing.

Patent JP-H02185139-A (JP)
Title: Private branch exchange
Inventor: IKEMORI KIMIO
IPC: H04L12/50
Filed: 1989-01-12
Abstract: PURPOSE:To suppress down of an exchange due to trouble of one trunk by detecting the extent of frequency step out between a synchronizing clock and the frame synchronizing signal outputted from a time division switch and sending the extracted synchronizing clock of a trunk itself to the time division switch at the time when this extent reaches a prescribed value. CONSTITUTION:Plural trunks T1 are provided with a function to send an extracted clock DS1, and each trunk compares the phase difference between the frame pulse outputted from a time switch and the clock extracted by itself to detect whether the phase difference is changed with respect to time or not; and when the extent of this change continues over a certain time, frequency step out is decided and the extracted clock DS1 is sent to the time switch from the trunk T1. Consequently, though one of plural trunks T1 which supplies the clock to the time switch stops clock supply because of some trouble, another trunk supplies the clock in place of this trunk to synchronize the time switch and the operation is continued.

Title: Rolling piston type rotary compressor
Inventor: WATADA MASAHIRO
IPC: F04C18/356
Filed: 1981-01-17
Abstract: PURPOSE:To improve compression efficiency by fixing a cylinder height to the difference between a bore diameter of a cylinder and an outer diameter of a roller at a set point, without adding an additional mechanism nor complicating a structure. CONSTITUTION:A ratio H/(DC-DR) (=K) of a height H of a cylinder 5 with a difference (DC-DR) between a bore diameter (DC) of the cylinder 5 and an outer diameter (DR) of a roller 8 is set at or around 1.65. In other words, since friction loss is reduced as the valve of the ratio is made large, K<1.0 is a desirable range. Also, the leak is lessened, the smaller the value of the ratio K, and K< 2.3 is a desirable range. Moreover, the smaller the value of the ratio (K), it is  better with regard to a refrigerant temperature increase inside the cylinder 5 and K<2.3 is a desirable range. Therefore, by setting the value of the ratio K at or around 1.65, friction loss, leak and refrigerant temperature increase are controlled and compression efficiency can be improved.

Filed: 1996-01-17
Abstract: PROBLEM TO BE SOLVED: To obtain an electromagnetic flowmeter by which a flow rate can be measured with good accuracy irrespective of whether the distribution of a flow velocity is symmetric with respect to an axis or not by providing an adjusting member which adjusts the gap between a conduit and an inner core and by which the distribution of a magnetic field inside the conduit is adjusted freely.

Title: Gas laser oscillator
Inventor: NAGAI AKIO
IPC: H01S3/03
Filed: 1978-01-23
Abstract: PURPOSE:To enable to avoid the damage of partial reflection mirror even at the high output laser oscillation, by increasing the oscillation efficienty and making stable the output, through flowing mixing gas to non-discharged part at all times. CONSTITUTION:A part of the circulating gas formed by fan 6 flows to the laser media 1 from each mirror of partial reflection mirror 4 and the full reflection mirror 3 for the non-discharge part 2 via the duct 11. The gas flow of the non-discharge part 2 blocks the absorption and heating of the laser oscillator and keeps the absorbed loss of the laser oscillator lower, allowing to increase the oscillation efficiency of the mixing gas of CO2 molecules. Further, since the non-discharge part 2 has low gas temperature, the output variation due to the fluctuation of gas temperature is  very less, and the heating work abnormal for the partial reflection mirror 4 can be  avoided, allowing to prevent the damage of the partial reflection mirror 4.
