Title: Manufacture of semiconductor device
Inventor: MOROZUMI YUKIO
IPC: H01L21/76
Filed: 1985-09-09
Abstract: PURPOSE:To eliminate a defect in an Si substrate, which is generated due to the pinhole parts of an oxidation-resistant film, and to contrive the improvement of the characteristics of an element by a method wherein the ratio of the single layer thickness of the oxidation-resistant film to the thickness of a first oxide film is made larger than the ratio of its dry etching rate to its dry etching rate. CONSTITUTION:An Si substrate 1 is heat-oxidized to form a base Si oxide film 2 and after a first Si nitride film 9 is grown thereafter in a decompression vapor-phase growing furnace, a wafer surface is subjected to a scrubber- treatment using a brush, and again a second Si nitride film 10 is grown and is subjected to a scrubber-treatment. Furthermore, a third Si nitride film 11 is grown thereafter, then a photo resist 5 is patterned. The Si nitride films 9-11 other than the element region are etched in CF4+O2 plasma of 0.4torr using the photo resist 5 as a mask. At this time, in spite of the existence of pinholes 6 in the Si nitride films 9-11, a detect that even the Si substrate 1 is etched is not developed after that etching.

Title: Head chip adhering method
Inventor: OURA KIKUO
IPC: G11B5/53
Filed: 1986-08-25
Abstract: PURPOSE:To improve the accuracy of fitting and positioning a head chip by bonding the head chip and a dog base plate with both the leg end surface of the head chip and the stepped surface of a notch jointed. CONSTITUTION:The head chip fixed part of the dog base plate 18 is worked and formed into the notch 19 with approximately the same or larger step than the thickness of a core chip 16. The stepped surface 20 of the notch 19 becomes a guide wall for rubbing together and positioning the leg end surface 17 of the chip 16, and is grounded and finished completely so that it can be flat. Then the base plate 18 is matched to the interval of aligning and fixing the chip 16, and aligned and fixed so that a side surface 20 can be confronted with the end surface 17. An adhesive is applied to the side surface 20, and the chip 16 and the base plate 18 are joined and stuck. Thus the chip 16 and the base plate can be simultaneously fixed by batch processing with the same positioning accuracy, whereby the accuracy of fitting and positioning the head chip can be improved.

Inventor: EGAWA YUKIO
IPC: G01L5/00
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To accurately detect the torque of a variable capacity compressor of an air conditioner for a vehicle. SOLUTION: When meteorological condition such as outside air temperature is measured (step 100), post-evaporator temperature is determined on the basis of the measured result and the set temperature in a vehicle room (step 102). From the post-evaporator temperature, the set pressure of a control valve is operated, and a flowing current to a solenoid is set to obtain the set pressure (steps 104, 106). From the set current and the meteorological condition such as outside air temperature, compressor torque is operated. On the basis of the operated result, ISCV is controlled, and the number of revolution of an engine is kept almost constant (step 108, 110).

Filed: 1988-08-10
Abstract: PURPOSE:To simplify the constitution of a large number of usual stations by applying polling from a management station to other usual stations, building up a logic ring based on the reply and applying multiple address notice of the logic ring data to each usual station. CONSTITUTION:A polling frame 1 inviting the subscription of a logic ring from a management station 1 to a usual station 2 is sent. When the usual station 2 receiving the frame desires to be subscribed with the logic ring a subscription request from 2 is returned to the station 1. Then a similar polling frame 3 is sent from the management station 1 to the usual station 3. When the usual station 3 does not desire to subscriber with the logic ring, a subscription reject frame 4 is returned. This is similarly applied also to usual stations 4-N. Thus, the management station 1 stores a reply obtained from each usual station to a network management information table and the content of the table is informed to all the usual station in multiple address. Thus, the constitution of each usual station is simplified and the entire network is formed inexpensively.

Title: Control circuit for dc motor
Inventor: YAGUCHI OSAMU
IPC: H02P7/288
Filed: 1988-08-10
Abstract: PURPOSE:To inhibit inversion starting by reaction at the time of forced stoppage by detecting the induced voltage of a motor and connecting a capacitor to the base of a transistor for detecting rotation holding the continuity of transistors for forward rotation and reverse rotation. CONSTITUTION:When a motor M is turned in the forward direction by external force, a transistor Q11 for detecting rotation is turned ON by the induced voltage of the motor M. Consequently, drive transistors Q12, Q32 are turned ON, and the motor M continues its forward rotation. The transistor Q11 for detecting rotation is turned OFF instantaneously for a specified period during the revolution of the motor M. However, a control circuit is kept at ON so far as the motor M is revolved. When the motor M is controlled by an external force, the transistor Q11 for detecting rotation cannot be turned ON further. A transistor Q21 for detecting the rotation in the reversal direction is reverse-biassed by a capacitor C22, thus preventing the possibility of reverse starting.

Title: Desalter
Inventor: INAGAKI SEIICHI
IPC: C02F9/00
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To almost surely prevent the scaling on an ion-exchange membrane provided in an electric deionizer and to obviate the deterioration of the ion- exchange membrane by arranging an ion exchanger in the front stage of the deionizer. SOLUTION: An ion exchanger 2 packed with a weakly acidic cation- exchange resin is arranged in the front stage of an electric deionizer 3. Consequently, the treated water almost free from the ions such as Ca<2+> and Mg<2+> as the hardness components which have not been removed in a reverse-osmosis membrane device 1 is introduced into the deionizer 3, and the scaling on the ion-exchange membrane provided in the deionizer 3 is almost surely prevented. Since the weakly acidic cation-exchange resin highly selective to the hardness components such as Ca<2+> and Mg<2+> and lowly selective to the univalent ions such as Na<+> is used, an increase in the running cost of the desalter due to the high regeneration frequency of the weakly acidic cation-exchange resin is suppressed.
