Title: Intake manifold of internal combustion engine
Inventor: ONISHI KAZUHIKO
IPC: F02M35/10
Filed: 1992-05-30
Abstract: PURPOSE:To improve the performance of distributing a mixture and stabilize combustion by forming ribs inclined to the predetermined direction while crossing the direction of flow along fuel wall flow on the surface of a turning inside wall in a turning path part of a manifold intake path. CONSTITUTION:An intake manifold 34 has two manifold intake paths 48 provided in the intermediate part respectively with turning path parts 94 and is provided on the inside wall surface 96 in the turning path part 94 with a rib 98. The rib 98 crosses the direction of flow along a fuel wall on the surface 100 of a turning inside wall in the most projecting part of the turning path part 94 while being formed with a fixed height from the innermost inside wall surface 102 of the turning inside wall surface 100. Also, the rib 98 is inclined by a predetermined angle to the direction of flow along the fuel wall of inside path wall surface 96 in the upstream of the turning path part 94 toward the downstream side. Thus, even in the start of a cooler of an engine, the flow along the fuel wall easily drifts away from the fuel wall to improve the performance of distributing a mixture.

Title: Method for controlling hearth roll temperature of continuous annealing furnace
Inventor: YAMAGUCHI YASUHIRO
IPC: C21D11/00
Filed: 1984-08-04
Abstract: PURPOSE:To prevent the meandering of a thin steel sheet in a continuous annealing furnace and the deterioration of the quality thereof owing to a temp. difference between the steel sheet and hearth rolls in the stage of changing over the heat pattern of the steel sheet in the furnace by approximating quickly the temp. of the hearth rolls in the furnace to the temp. of the steel sheet to be passed therethrough. CONSTITUTION:The thin steel sheet 2 is passed through the continuous annealing furnace consisting of a heating zone 4, a soaking zone 6 and primary, secondary and tertiary cooling zones 8, 10, 12, by which the steel sheet is annealed. There is a large difference in the temp. of the steel sheet entering the secondary cooling zone 10 in the stage of changing over the heat pattern in the averaging treatment and cooling treatment of the steel sheet to be annealed and since the steel sheet is thin, the set temp. is easily attained by a cooling gas but the hearth rolls 14 has large heat capacity and cannot follow up easily such temp. change. The temp. difference is thereby produced between said rolls and the sheet 2 and the meandering of the steel sheet or the rugged crowns to the hearth rolls is generated. The quality of the steel sheet is thus deteriorated. The generation of the above-mentioned defect is prevented by heating or cooling the hearth rolls and approximating quickly the temp. thereof to the preset temp. of the steel sheet.

Title: Compound semiconductor device
Inventor: ONAKA SEIJI
IPC: H01L29/73
Filed: 1986-07-11
Abstract: PURPOSE:To reduce the step difference on the surface and to increase the operating speed, by shorting the collector and the emitter of a second TR on the surface of the collector layer of a first transistor TR, and decreasing the contact resistance of the first TR. CONSTITUTION:The structure of a second TR (d) is provided at a contact part 11 of a collector (c) of a first TR (f). The emitter of the second TR is the collector of the first TR. The base and the collector of the second TR are shorted. Thus the contact resistance value of the collector of the first TR is decreased. In this equivallent circuit, the second TR is operated in a saturated region. Therefore, the voltage drop in the second TR is Small. Contacting can be performed at a low resistance value. Thus the device can be operated at a high speed. Since the first and second TRs can be formed in the same process, the step differences at, e.g., a p-type InGaAsP base layer 4, an n-type InP emitter layer 5 and an n<+> type InGaAsP contact layer 6 can be made extremely small.

Title: Quartz glass member suppressed from becoming dense due to irradiation of uv ray
Inventor: KOMINE NORIO
IPC: G03F1/60
Filed: 1995-06-29
Abstract: PURPOSE: To obtain such a synthesized quartz glass suitable for an optical system of photolithography that the structure is suppressed from becoming dense due to irradiation of UV rays in a specified wavelength region by controlling the conc. of OH groups in the quartz glass member to a specified value or smaller and adding hydrogen molecules to the member. CONSTITUTION: This quartz glass member has a low OH group conc. as <=200ppm. Even when the quartz glass member is irradiated with UV rays or excimer laser beams in a specified wavelength region of <=400nm for a long time, the increase in the refractive index, generation of strain and recession of the surface can be suppressed. Therefore, a lens comprising this glass member shows no deterioration of focusing performance even when the glass is irradiated with UV rays for a long time. Moreover, by adding hydrogen molecules to the glass member to obtain >=1×10<17> molecules/cm<2> hydrogen molecule density, the glass member is more suppressed from becoming dense.

Title: Frame out of synchronism detection system
Inventor: MATSUI HITOSHI
IPC: H04L7/08
Filed: 1989-06-26
Abstract: PURPOSE:To surely detect out of frame synchronization by varying a pattern of a transmission signal sent to a transmission line synchronously with a frame synchronizing signal. CONSTITUTION:A decision pattern is selected synchronously with a clock signal in 343Hz given to a mapping device 2 at a deciding device 5 and an output signal of a demodulator 4 is decided by the decision pattern corresponding to the signal point arrangement pattern of the mapping device 2. A Viterbi decoder 6 decodes the output signal of the device 5 and outputs the result of decoding as a reception signal. A detector 7 detects a decoding error from the internal state of the Viterbi decoder 6. When a frame synchronizing signal is out of synchronism, since the 343Hz clock signal supplied to the mapping device 2 and the 343Hz clock signal supplied to the device 5 have a shift, a synchronization between the mapping and the deciding is lost and correct demodulation is attained by the Viterbi decoder 6. Thus, the detector 7 detects out of frame synchronization.

Abstract: PURPOSE:To improve a washing speed fro a ground object, when it is removed, and reduce an inferiority rate, by applying an ultraviolet ray hardening type adhesive agent to the forced contact periphery between the ground object and a grinding bed and hardening the ground object to be fixed by irradiating ultraviolet rays, in the case of manufacture for a floppy head or the like. CONSTITUTION:The method, forcing a ground object 1 of ferrite and ceramic or the like to be brought into contact with a grinding bed 2 while applying a fixed pressure or an attracting pressure by magnetic force or a vacuum source, applies an ultraviolet ray hardening type adhesive agent 3 of low viscosity to the forced contact peripheral part between said object 1 and said bed 2 and hardens the object to be fixed by irradiating ultraviolet rays while applying the pressing force or the attracting pressure.
