Patent JP-S5565000-A (JP)
Title: Pressing device
Inventor: NISHIOKA YASUYUKI
IPC: B30B9/12
Filed: 1978-11-11
Abstract: PURPOSE:To enable even the fluid and low viscosity raw liquid to be pressed by mounting an elastic force feed member in the continuous screw path of a feed port for slurry-form raw liquid such as activated sludge and further providing a perforated guide member for causing subsequent raw material force feed action of said elastic force feed material and a check valve. CONSTITUTION:A plate-form body 17 being an elastic force feed member turns subsequently along the vane surface from the beginning end part of screw blades 5 along with turning of a rotary pressing member 6 and the slurry-form raw liquid from a feed port 13 is force advanced by the sliding movement of the slide roller 18 in the bottom end part thereof, thus the liquid is subjected to ordinary pressing transfer action. Next, the raw liquid is further advanced to the transfer direction from the gap of a perforated guide member 19, and becomes the ordinary pressing- transferring state. The plate-form body 17 is again reset to the beginning end part of the screw blades by compression of a spring 15 along the guide face of the member 19. The pressed liquid is separated to filtrate 24 and cake 26 by the filter cloth 4 during pressure feeding to the outlet side. The back flow of the raw liquid is prevented by the check valve 21 in the transfer path, thus smooth pressure feeding is accomplished.

IPC: H01L21/205
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To prevent hydrogen, causing drop in In intake rate, from being fed onto a substrate by providing a piping for supplying group V material to a reaction furnace with a unit for decomposing group V material and a unit for adsorbing decomposed hydrogen through a hydrogen occlusion alloy in front of the reaction furnace. SOLUTION: A group V material, i.e., NH3 , fed from a supply line 1 is thermally decomposed by means of a heater 8 and decomposed gas is introduced to a hydrogen adsorbing unit 9 encapsulating a hydrogen occulusion alloy. On the other hand, NH3 introduced from the line 1 and decomposed by the heater 8 is fed to a hydrogen removing unit 9 and only hydrogen is discharged through a hydrogen transmitting Pd alloy film. At the time of growing InGaN, NH3 is thermally decomposed by the decomposition heater 8 and introduced to the hydrogen removing unit 9 before being fed to a reaction furnace thus preventing hydrogen, causing drop in In intake rate, from being fed onto a substrate.

Title: Host equipment, synchronous communication system, communication interference preventing method and computer readable storage medium recording communication interference prevention program
Inventor: SATO KOJI
IPC: H04W84/20
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To reduce communication interference when plural kinds of synchro nous communication exist in the same space by determining the change of synchronous communication timing on the basis of values counted by an error counting means and the other system packet counting means. SOLUTION: A judging means 105 is activated in each fixed cycle and determines a change in the timing of synchronous communication on the basis of counter information provided by an error counting means 103 and another host packet counting means 104 and that determination is reported to a communication timing control means 102. On the basis of control information reported by the judging means 105, the communication timing control means 102 operates to change the synchronous communication start timing of a host. Thus, since the synchronous communication timing is changed by operating host equipment, on the condition of considering communication blocking caused by an influence from the other system, the host can avoid the influence of the communication blocking by delaying the synchronous processing start timing.

Title: Read-, write head separated disk device
Inventor: TANAKA ATSUSHI
IPC: G11B20/10
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To shorten seek time and increase the number of processed I/Os per unit time by using plural independent head positioning mechanisms, heads for read only, heads for write only, and a disk controller which controls the processing order of I/Os coming from the host device. SOLUTION: In a read-write head separated disk device 100 composing a log-structured file(LFS), processing is performed by write-only heads 130-135; no read (in general, indifferent from write processing) interrupts the processing; and write data is written successively in the order of generation. Hence especially seek time is shortened and write performance is improved. Compared with the conventional plural head positioning devices, read processing in this case is unvaried in the number of read processing. However, since processing is performed by read-only heads 110-115, elevator seek is conducted and seek time is shortened when read address is related.

Title: Seek control method in reproduction device of disk-shaped storage medium
Inventor: TOMIJIMA YUICHIRO
IPC: G11B21/08
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To provide seek control technique that can accurately move a pickup to a target track even when a mirror signal is lost during seek and prevent drive damage caused by reckless seek regarding a track zero-cross detection seek control method. SOLUTION: In a seek control method, a mirror signal for indicating l track in the radius direction of a disk in 1 cycle is counted by a CPU for system control for each 1 cycle, and at the same time a pickup is moved until the number of count coincides with the number of tracks to a target track. The CPU checks the cycle of the continuous mirror signal, and executes either of the addition correction mode of the number of count or the subtraction correction mode of the number of tracks (step 118) when abnormal deviation exists in the previous or succeeding cycles (step 112). When there is a defect in focus servo and a disk and a rear mirror signal is not counted within a specified time, the forced stop mode of the pickup is executed (step 122).

Title: Adjusting device of inclining quantity of wheel head for surface grinder
Inventor: KOMATA TSUNEO
IPC: B24B47/10
Filed: 1982-08-12
Abstract: PURPOSE:To enable to adjust accurately an angle of inclination of a grinding wheel, by a method wherein a first shaft meeting at right angles with an axis of the grinding wheel is supported by a bed and a wheel head is supported rotatably through a second shaft which meets further at right angles and connects with the first shaft. CONSTITUTION:To incline an axis O-O of a grinding wheel, inclinations 41a-41b are adjusted by turning a wheel head 20 around a second shaft 19 connected with a first shaft 12 through joint operation of movement of a ball 31 by a bolt 27 and turning of a bolt 35. Then, to incline the axis O-O of the grinding wheel in a direction meeting at right angles with this turning direction R, a separate inclination of the axis O-O is adjusted by turning the wheel head 20 around the first shaft 12 to a bracket 23 protruded more than a base 10 by making turnings of bolts 21 and 22 operate jointly. Thus, even in case of adjustment of an angle position by slackening these bolts which are an angle position adjusting system, an inclination angle of the grinding wheel can be adjusted accurately without causing slippage of the wheel head owing to its empty weight.
