Title: Manufacture of semiconductor device
Inventor: MATSUNO TOMOYUKI
IPC: H01L21/76
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To reduce the crystal defects present in the silicon bulk of only an element activating region of a semiconductor substrate, by forming a field oxidation film on the surface of the semiconductor substrate through a selective oxidation method, and by thereafter heat-treating the substrate in an atmosphere containing hydrogen, using the field oxidation film as a mask. SOLUTION: After a field oxidation film 2 is formed on a silicon substrate 1 by a selective oxidation method, using this field oxidation film 2 as a mask, the silicon substrate 1 is heat-treated with a hydrogen gas. Resultantly the surface of the silicon substrate 1 is annealed by the hydrogen gas, the crystal defects present in the silicon bulk of an element activating region (a) of the silicon substrate 1 are reduced and inactivated. Also, since no crystal defect present in the silicon bulk of a region (b) below the field oxidation film 2 of the silicon substrate 1 is reduced and the crystal defects or interstitial oxygens present in the silicon bulk of the region (b) remain as they are, a gettering effect is maintained and slip, etc., are hardly generated. Thereby, the crystal defects present in the silicon bulk of only the element activation region (a) can be vanished.

Abstract: PURPOSE:To reduce the cost and save the space by providing an air vent formed in an upper panel and suction holes which suck the air flow in a casing, and then efficiently removing dust staying at the periphery of equipment which exerts adverse influence upon inspection. CONSTITUTION:A laser microscope (precise inspection and measuring instrument) 39 is covered with the casing 55, and the air vent 42 for taking a down flow F (air flow) in a clean room 41 in the laser microscope 39 is formed in the upper panel 40. Then 1st and 2nd suction holes 43a and 44a which suck the down flow F which is taken in are formed by an Xy stage 24 and below a support base 26. Then a down flow F' moving from the upper panel 40 to the suction holes 43a and 44a are formed in the lower microscope 39. Consequently, the dust produced at the periphery of the stage 24 is discharged to the outside of the casing 55 through the suction holes 43a and 44a with the air flow, so the need for a clean bench is eliminated.

Title: Fuel injection device
Inventor: TAKAYAMA TERUO
IPC: F02M69/00
Filed: 1986-02-05
Abstract: PURPOSE:To obtain silencing effect by arranging a device for absorbing pressure pulsation in a passage for returning fuel from a pressure control valve for supplying fuel of a constant pressure to a fuel injection valve to a fuel tank. CONSTITUTION:Fuel pressurized with and sent forth from a fuel pump 10 enters via a filter 11 a 1st damper 12 where pressure pulsation is absorbed and is sent to a fuel injection valve 13. When the fuel pressure reaches or exceeds a specified value, a valve 14a of a pressure control valve 14 opens to return fuel via a return passage 16 to a fuel tank 9. Here, while the fuel which has passed the valve 14a is suddenly released from a pressure and produces vapor and pressure pulsation increases, since a 2nd damper is interposed in the return passage 16, the pressure pulsation is absorbed. Thus, the sound from the return passage is prevented from being produced.

CONSTITUTION:When a switch 12 is switched to a recording R side, a readout W head 5 has a function as an R head, and a readout signal is sent to a data block interval (IBG) detecting circuit 21 through a demodulating circuit 20. When the IBG has been detected by the detecting circuit, the switch 12 is switched to W side again, and the W head is connected to a record modulating and driving circuit 11 being an original circuit system. This modulating circuit 11 starts to erase from the time when the switch 12 is switched in accordance with an instruction from a controlling circuit 13, and error data is erased. After the head has run by a prescribed distance, the record modulating and driving circuit 11 is changed to a recording mode, and recording of data is continued.

Title: Automatic production system for system flow
Inventor: NAITO ICHIRO
IPC: G06F17/50
Filed: 1987-02-04
Abstract: PURPOSE:To automatically produce the system flow specification information with which the manual correction time is reduced, by deleting a program which sorts the corresponding input file in the existing system flow specifications when the arranging orders are equal between the input/output files and the slip data in said specifications. CONSTITUTION:The information on the arranging orders of the input/output files and the slip data of the subject jobs are used to decide whether the sorting processing is needed or not for the input files described on the system flow parts which are selected, corrected and connected to each other. If said arranging orders are equal, the relevant sorting program is deleted. At the same time, the program pattern names corresponding to the slip output programs in a produced system flow are allocated based on the information on the number of control breaks of an output slip. Thus it is possible to complete automatically the system flow specifications having a higher degree of completion than a conventional system. Then the manhour can be reduced for manual correction of the produced system flow specifications.
