Title: Wafer pre-alignment device
Inventor: YOSHIDA MINORU
IPC: H01L21/027
Filed: 1982-10-06
Abstract: PURPOSE:To realize approximate positioning of wafers with high efficiency without damaging them by a method wherein at least two photoelectric components are provided arranged within a distance of an orientation flat length and the orientation flat part of the wafer is detected. CONSTITUTION:Wafers 1 are delivered onto an X-Y parallel traveling table 6 by a belt 20 and attracted by vacuum pits 18. Two of photoelectric components 33-1-33-6, which are facing each other are designated as a pair and the X table 13 and the Y table 8 are moved by the difference of the output signals from above pair of the photoelectric components so as to make those signals equal and the wafer 1 is adjusted to the center of the rotating table 24. A vacuum pit 31 is made vacuum and the wafer 1 is transferred onto the rotating table 24 and the wafer 1 is rotated. When an orientation flat 2 is detected by a photoelectric switch 34, the photoelectric components 35-1, 35-2 start detecting and when the output signals from above two components become equal to each other, the rotation is stopped and the pre-alignment is finished.

Title: Method and device for simultaneous measurement of different species of ions
Inventor: HANAOKA YUZURU
IPC: G01N30/38
Filed: 1983-09-21
Abstract: PURPOSE:To determine quantitatively and analyze both anion and cation species contained in a liquid to be measured with one time of measurement by providing respectively anion and cation exchange columns and treating continuously the liquid to be measured. CONSTITUTION:The liquid to be measured in a measuring pipe 3g is conveyed to the eluate from a liquid feed pump 2 via a sampling valve 3 and is supplied to a cation exchange column 4. The cation species in the liquid to be measured is separated in said column 4 but the anion species passes through the column 4 without being separated. The eluate from the column 4 is then conducted to an anion exchange column 5 and the anion species in the liquid to be measured is separated. Such anion species and the cation species passed through the column 5 after separated in the column 4 are supplied to a detector 6. Both anio and cation species contained in the liquid to be measured are thus determined quantitatively and analyzed simultaneously with one time of measurement by treating the liquid in the above-mentioned way.

Title: Drive unit for tandem axle in vehicle
Inventor: ONO YUTAKA
IPC: F16H48/38
Filed: 1981-10-31
Abstract: PURPOSE:To improve fuel mileage by providing a differential gear lock in an intermediate differential gear and as well providing a synchronous engagement clutch in a front axle so that the front axle may be switched between its driven state and its undriven state. CONSTITUTION:Drive power from an engine is transmitted through an input shaft 29 to an intermediate differential gear unit A, and then, distributed to a first output shaft 47 and a second output shaft 32. The first output shaft 47 drives a front axle 39 through a clutch mechanism 43 and by way of gear wheels 15, 23, a bevel gear wheel 37 and a crown gear wheel 41. The second output shaft 32 drives a rear axle. The intermediate differential gear unit A is provided with a differential gear locking mechanism C for locking the first and second output shafts together. Due to the provision of the intermediate differential gear unit, both axles may be driven and as well the locking of the differential gear may be made as it is necessary. When the clutch is disengaged with both axles being driven in the differential gear locking state, the rear axle alone may be driven, thereby fuel mileage may be improved upon no load running.

Title: Knowledge base searching system
Inventor: ODA TOSHIHIKO
IPC: G06F17/30
Filed: 1990-07-02
Abstract: PURPOSE:To operate a high-speed searching process by searching the object being an object to be searched in the connection direction of a genealogical tree according to an index from a high-order class object searched by a width priority searching means. CONSTITUTION:When a class object 3(P) is searched, a designation P of the class object 3 to be searched and a designation C of the high-order class object 3 are set in an index setting means. Then, the width priority searching means width-priority searches each class object 3 from a root object 2 based on the index C, so that a class object 3(C) can be searched. Then, a depth priority searching means depth-priority searches each object 3 and 4 from the searched class object 3(C) according to the index P, so that an object 3(P) being the object to be searched can be searched. Therefore, a useless search for the objects 3 and 4 lower than the high-oder class object 3 can not be operated. Thus, a range to be searched is reduced so that the searching process can be operated at the high-speed.

Title: Phase comparator circuit
Inventor: SHIMIZU YASUNARI
IPC: H03L7/085
Filed: 1992-06-09
Abstract: PURPOSE:To accurately detect a phase error between a clock pit signal and a clock signal even when a level of an RF signal reproduced from a magneto- optical disk is fluctuated or an optical MTF is fluctuated. CONSTITUTION:A sample-and-hold circuit 4 samples and holds a differentiated, signal (b) resulting from differentiating a clock pit signal (a) by a differentiation device 3 at an edge c1 at a prescribed timing of the clock signal generated by a PLL circuit 5. A detection circuit 12 detects a tilt in the differentiated signal (b) outputted from the differentiation device 3 and outputs a detected tilt alphai to a divider 11. The divider 11 divides a level phii at a prescribed timing of the differentiated signal (b) outputted from the sample-and-hold circuit 4 with the tilt alphai outputted from a sample-and-hold circuit 22 and outputs the quotient to the PLL circuit 5. The PLL circuit 5 generates the clock signal corresponding to the signal inputted from the divider 11.

Title: Inspecting method for die casting
Inventor: SHINOZUKA MASAO
IPC: G01B13/00
Filed: 1990-07-04
Abstract: PURPOSE:To make quick and correct inspection by a method wherein an instrument approximately in the same shape as a deep hole and having a void thereinside is inserted in the deep hole, a gas is let into the void, and the shape of the deep hole is determined from the pressure of the gas. CONSTITUTION:A detecting instrument 8 approximately in the same shape as a deep hole and having a void formed thereinside is pressed against a sheet face 5 of the deep hole which has the thickness (h) of about 40mm. The leaking degree at the sheet face 5 is determined by adding the air pressure to the sheet face. In other words, the factory air is received by a primary pressure sensor 9 and set to a set pressure by a regulator 11. When the instrument 8 is pressed to the sheet face 5 with this pressure, if the sheet face is normal, the pressure is maintained without a secondary pressure sensor 12 being decreased. However, if the sheet face is defective, the pressure is reduced. Therefore, quick and correct inspection is achieved.

Title: Flame-retardant polybutylene terephthalate resin composition
Inventor: OHARA SHINJI
IPC: C08L71/00
Filed: 1994-07-27
Abstract: PURPOSE:To prepare a flame-retardant resin compsn. which is improved in the appearance when molded, melt processing stability, and mechanical properties without detriment to the flame retardancy by incorporating a brominated phenoxy resin flame retardant and antimony tetraoxide into a polybutylene terephthalate resin. CONSTITUTION:A resin compsn. comprising 100 pts.wt. polybutylene terephthalate resin, 5 to 40 pts.wt. brominated phenoxy resin flame retardant, and 1 to 25 pts.wt. antimony tetraoxide having an average particle diameter of not more than 2mum. The antimony tetraoxide is selected because it has no catalytic activity for polymerization. An average particle diameter exceeding 2mum is unfavorable, because it leads to the deterioration in mechanical properties, particularly tensile elongation and Izod impact strength. In general, increasing the amt. of an antimony compd. contributes to an improvement in flame retardancy. The antimony tetraoxide added in an amt. up to 25 pts.wt. can develop satisfactory flame retardancy. When the amt thereof exceeds 25 pts.wt., scarcely any further improvement in flame retardancy can be attained.
