Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a wafer adapter which can perform an epitaxial growth test in an epitaxial growth furnace with a handling robot at a low cost, and its using method. SOLUTION: A small diameter wafer 15 for testing or monitoring which is smaller than an epitaxial wafer, or chip wafers 22a, 22b are mounted on a mounting pocket 16 on the surface of a wafer adapter 10. After that, the adapter 10 is inserted in an epitaxial growth furnace 11 by a robot. In the furnace, silicon single crystal is epitaxially grown on the surfaces of the wafers 15, 22a, 22b for test. Next, an adapter 19 is automatically taken out to the outside of the furnace. Thereby the wafers 15, 22a, 22b for tests which are smaller than the epitaxial wafer can be dealt with in an epitaxial growth furnace with a robot, for the exclusive use of a wafer having the same form as that of the epitaxial wafer.

Title: Method for analyzing thermal decomposition reaction of solid
Inventor: ARII TADASHI
IPC: G01N25/20
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To enable the calculation of the activation energy E of a thermal decomposition reaction by performing a CDRC(constant decomposition rate control) method at different reaction rates and analyzing measured results in a specific analytical technique. SOLUTION: For example, sample temperature Ta and Tb at the point of reaching three reaction rates αx, αy, and αz are each found, and from them three types of activation energy Ex, Ey, and Ez are calculated. Then it is possible to find final activation energy E from the average value of the three. The activation energy E is compared with n-pieces of activation energy Ei. Then an Ei that is the closest to the activation energy 5 is selected, and a reaction model expression f (α) corresponding to the Ei becomes the most reliable reaction model expression f (α) of the measured thermal decomposition reaction. Once the expression f (α) is decided, a previous exponential factor A is obtained from the intercept of the straight line of the expression of (α).  By this, the previous exponential factor A and the function form of the activation energy E and the reaction model expression f (α) are all obtained, and the thermal decomposition reaction is elucidated.

IPC: H04B10/291
Filed: 1994-08-15
Abstract: PURPOSE:To make the system scale small and facilitate the alterations of node arrangement by distributing sent signals from respective nodes in the same transmission frequency group to respective row or column groups and performing frequency multiplexing, and distributing and transmitting the signals to plural nodes. CONSTITUTION:Optical switches 109 to 111R or C distribute the sent signals from signal transmitting means of respective nodes 1 to 9 in identical transmission frequency groups 1 to 3 by the row or column groups. The signals by the groups 1 to 3 are frequency-multiplexed by star couplers 112 to 114R or C, and distributed and transmitted by optical switches 115 to 117R or C to the respective nodes 1 to 9. The respective nodes communicate with one another by using packets which have destination addresses and origination addresses indicating the destination and origination nodes at their header parts and sent data at information parts. Consequently, the frequency multiplicity is reduced to suppress the increase in the scale of the system, and the node arrangement can easily and speedily be altered.

Title: Intake air controller for engine
Inventor: TSUYUKUCHI MICHIYASU
IPC: F02B29/08
Filed: 1987-07-31
Abstract: PURPOSE:To prevent some accelerating hesitation and a large torque shock from occurring by temporarily stopping the execution of an inflow timing lag in intake air at the time of quick acceleration. CONSTITUTION:A control unit U controls a timing advance mechanism 26 of a timing valve 16 on the basis of each signal out of a sensor 31 detecting the opening of a throttle valve 14, a sensor 32 detecting engine speed and a sensor detecting engine cooling water temperature, and also controls the inflow timing of intake air into an operating chamber 6. Here, at the time of quick acceleration shifting from an area, where the engine speed and the throttle opening are expressed as a parameter and quick-closing of the intake air is performed, to an area where slow-opening of the intake air is performed, this transition is delayed as long as the specified time. With this constitution, a sudden increase in an intake air quantity, that is, the extreme leanness of an air-fuel ratio is prevented from occurring, whereby any accelerating hesitation is eliminated and, what is more, a large torque shock at the point of time when response of a fuel supply has been overtaken is prevented from occurring.

IPC: H02K37/16
Filed: 1981-12-01
Abstract: PURPOSE:To obtain a low-cost liquid crystal watch by insulating a coil winding core or a coil winding core and a york from a base plate. CONSTITUTION:A completed coil 24 consists of a coil winding core 14, a terminal board 15, a winding frame 17, and a coil 18. The coil 24 is incorporated into a york 13 by inserting a tube 12 into fixing holes 14c, 14d drilled into the winding core 14. Since an insulating part 16a is formed on the upper and lower surfaces of the core 14 at the fixing hole 14C side, the core 14 is insulated from other parts even if coupled with a screw 22. Namely the core 14 is insulated from a base plate 11 and reference voltage is not applied to the core 14, so that when the coil 18 is directly wound around a winding part 14e of the core 14, battery capacity is not reduced because current does not flow into a driving circuit differently from conventional methods.

Title: Stripping agent composition
Inventor: SATOU MITSUYOSHI
IPC: A61K8/00
Filed: 1983-10-17
Abstract: PURPOSE:To provide a stripping agent which has is low in toxicity, good adhesion to the surface of an adherend, a potent effect of inhibiting the evaporation of solvents contained therein and excellent stripping characteristics, by blending acetone, hydroxypropylcellulose and wax. CONSTITUTION:A stripping agent consists of acetone or a solvent mixture of acetone and ethyl alcohol. Acetone used in the agent is a preferred main solvent which is relatively low in toxicity as a stripping agent for 2-cyanoacrylate adhesive. Ethyl alcohol may be mixed as a co-solvent to increase the solubility of hydroxypropylcellulose. Hydroxypropylcellulose plays chiefly a role of inhibiting the evaporation of the solvents after thickening and film formation. By inhibiting the evaporation of the solvents, the agent can retain a suitable viscosity and adhere well to the surface of an adhered, and hence the solvent action on a cured adhesive can persist.
