Title: Back-etching apparatus for x-ray mask
Inventor: OTA TSUNEAKI
IPC: H01L21/027
Filed: 1993-10-08
Abstract: PURPOSE:To protect a membrane from deformation and breakage even if the force applied to the rear of an Si substrate changes with the change of the quantity and concentration of etchant such as KOH by a method wherein the force applied to the surface of the Si substrate is always made equal to the force applied to the rear. CONSTITUTION:An opening 5 containing air at a position whose depth from the liquid surface of etchant 3 is equal to the depth of the position at which an opening 7 with an Si substrate 6 attached is provided is connected to the surface of the Si substrate 6 air-tightly with pipes 4 and 11, etc., to apply always a pressure equal to a pressure applied to the rear of the Si substrate 6. Although the quantity and concentration of the etchant 3 changes in accordance with the progress of a back-etching process and the pressure applied to the rear of the Si substrate 6 accordingly, the pressure equal to the pressure applied to the rear of the Si substrate 6 is always applied to the surface of the Si substrate 6.

Title: Controller of centrifugal machine
Inventor: HOSHIBA HIDEKI
IPC: B04B13/00
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To obtain specified deceleration power and to suppress the abnormal tones based on the resonance phenomenon of an electrical frequency on control and the mechanical natural oscillation frequency of an induction machine by making the pulse patterns to be fixed uniform. SOLUTION: At the time of DC brake, the operation state of a pulse forming logic 3 is inputted to a CPU 1 through, for example, a signal line 9 from an AND circuit 7. When this state is inputted thereto, the count value for switching patterns of pulses outputted by the pulse forming logic 3 is written from the CPU 1 to a timer counter 2. The timer counter 2 outputs the one shot for switching to the pulse forming logic 3 after the end of the counting. As a result, the pulse forming logic 3 shifts the pulse patterns and selects and fixes the pulse patterns at which the DC brake is most applied, thereby controlling the deceleration of a motor 5.

Title: Method and device for controlling electrically-driven injection molding machine
Inventor: SHIMIZU MIYUKI
IPC: B29C45/77
Filed: 1991-09-30
Abstract: PURPOSE:To heighten the quality of molded objects by a method in which injection pressure is detected in the whole sections of the injection process containing filling process and dwell process, and while the value of detected pressure is feed back- controlled to the injection pressure so that said value coincides with a pressure- commanding value, simultaneously the injecting speed is controlled so as not to exceed the limit value of speed. CONSTITUTION:Since filling pressure is relatively small in the beginning of filling process, while the difference between the detected value Dp of pressure and the command value Pf of filling pressure becomes large, injection speed also further becomes large, but the injection speed is controlled by speed-controlling part 7 so that it becomes speed-limiting value Vu. On one hand, the filling pressure becomes also large with the advance of the filling process, but after the detected value Dp of the pressure has reached the magnitude of the filling pressure generated on the basis of the speed- limiting value Vu, the filling pressure Dp is controlled so as to coincide with the command value Pf of the filling pressure. When said process is moved to a dwelling process correspondingly to the position of a screw, the detected value Dp of dwelling pressure is feed back-controlled so as to coincide with the command value Pn of dwelling pressure.

Title: Treating agent for heavy metal-containing waste and stabilizing method of heavy metal-containing waste
Inventor: IKEDA KOICHI
IPC: A62D3/33
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To completely stabilize a heavy metal-containing waste by incorporating a latent hydraulic material and a boron compound to prepare a treating agent for the heavy metal-containing waste. SOLUTION: The latent hydraulic material used as an essential component does not cause hydration reaction with water alone and, for example, causes hydration reaction with the addition of a stimulating agent and for example, a blast furnace granulated slag or a converter slag is used.

Title: Four-way selector valve
Inventor: OGAWARA YASUHITO
IPC: F16K11/065
Filed: 1996-10-22
Abstract: PROBLEM TO BE SOLVED: To provide a four-way selector valve for switching cooling and heating circuits without generating refrigerant leak so as to prevent lowering of cooling- heating capacity by forming an opening part, formed at a seat face in contact with a valve seat part of a slide valve, into a shape corresponding to the cross- sectional shape of a passage formed at the valve seat part. SOLUTION: Either one of two switching passages 9, 10 formed at a valve seat part 8, and a spectacle-shaped opening part 34 with a circular part connected to cover a second fluid passage are formed at a seat face 16 of a toilet seat 33. Since a slide valve 32 is brought into contact with a valve seat part 8 through an O-ring, sealing performance is improved, and refrigerant leak can be positively prevented. The passage resistance of refrigerant is therefore reduced, and the refrigerant flows smoothly to display requested cooling-heating capacity. Since leakage between low pressure and high pressure refrigerant is reduced, cycle hunting is eliminated, and cooling-heating capacity is improved also for this reason.
