Title: Device for extending microcomputer system bus
Inventor: ASANO TORU
IPC: G06F13/18
Filed: 1991-11-21
Abstract: PURPOSE:To evade bus competition owing to the delay of a signal by adding a forcible busy signal generating circuit, and thereby precedingly receiving a BUSY signal in a first microcomputer system. CONSTITUTION:The first and second microcomputer systems 1 and 2 are connected with first and second driver/receiver circuits 10 and 11 and a cable. When the second microcomputer system 2 requests a bus so as to output a bus request signal (BREQ) 13, a priority deciding circuit 3 returns a bus priority signal (BPRN). In this case, the forcible busy signal generating circuit 16 forcibly permits the busy signal (BUSY) 9 on a system bus at the first microcomputer 1 side to be valid immediately after BPRN 8 is returned. Thus, the bus competition which occurs when the first microcomputer system 1 with high priority requests the bus after the second microcomputer system 2 requests the bus is avoided.

Title: Photo-activity holding method for film-like photosensitive material and manufacture of printed wiring board
Inventor: TSUCHIYA KATSUNORI
IPC: G03F7/16
Filed: 1994-12-09
Abstract: PURPOSE: To irradiate a film-like photosensitive material laminated under reduced pressure with good reproducibility and high efficiency with actinic rays by holding the film-like photosensitive material laminated on a base under reduced pressure until the irradiation with the actinic rays and radiating the actinic rays in the chemically inert atmosphere. CONSTITUTION: A film-like photosensitive material laminated on a base under reduced pressure is held until the irradiation with the actinic rays and is irradiated with the actinic rays in chemically inert atmosphere. The atmosphere not hindering the photo- reaction such as the photo-polymerization or photo-cross-linking when the active light is illuminated, e.g. nitrogen gas, may be used for the chemically inactive atmosphere. The decompressed state may be used for this chemically inactive atmosphere, however the atmospheric state is preferable in view of the irregularity following property and adhesiveness of the photosensitive layer on the base.  The film-like photosensitive material laminated under decompression is preferably held in the chemically inert atmosphere immediately after lamination because the photo-activity is decreased in response to the period after the photosensitive material is returned to the atmospheric pressure from decompression after lamination.

Title: Method for inspecting leak of sheet seal part
Inventor: NISHI KAZUICHI
IPC: G01M3/02
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To efficiently surely inspect a leak of a seal area at low inspection cost by forming a space between a band-shaped coat member and a boundary part of sheet seal parts, using the space as a leak inspection hole, applying or reducing a pressure from the hole and detecting a change of a pressure value. SOLUTION: Leading end faces of sheets 1A, 1B are butted. A seal sheet 2 is overlapped on upper faces 12a, 12b of the sheets and heated, thereby fusing the sheets. A seal part 100 of a water-shielding structure is formed. Two band- shaped coat members 4 each having a release paper tape 5 bonded to a nearly central area in a breadthwise direction of a lower face 41 are registered and bonded so that the central area agrees with a boundary part 3 between the sheets 1A, 1B and the seal sheet 2. As a result, each boundary part 3 is coated with the coat member 4, and at the same time a slight space is left by the tape 5, whereby a leak inspection hole 6 in touch with the seal part 100 is formed. One end 60 of the hole 6 is closed. The hole is pressurized with a positive pressure or depressurized with a negative pressure from the other end 61.  A change of a pressure value is detected, and the presence/absence of a leak is confirmed.

Title: Manufacture of semiconductor integrated circuit device
Inventor: MURAKAMI SHIGERU
IPC: H01L21/285
Filed: 1988-12-02
Abstract: PURPOSE:To completely fill the inside of a fine opening part used to connect an element to a wiring part with a first conductor layer and a second conductor layer by a method wherein the first conductor layer is deposited by a bias sputtering method and, after that, the second conductor layer is deposited by a vapor growth method. CONSTITUTION:An element region such as an impurity diffusion layer 4 or the like is formed on a silicon substrate 1; an interlayer insulating film 5 is deposited; after that, an opening 6 for wiring connection use is made in a desired position. Then, a tungsten silicide layer 9 is deposited by using a bias sputtering method by Ar ions. During this sputtering operation, a bias is applied also to the side of the silicon substrate; thereby, a deposition operation and a sputtering operation are executed simultaneously; it is controlled that the deposition operation at an upper end part of the opening does not progress. This is based on a principle that a sputtering efficiency is highest at an incidence angle of about 45 deg. of sputtering ions; when the bias is controlled, a deposition speed at the upper end part of the opening can be made zero and the deposition speed in a depth direction can be made high. After that, tungsten 10 is grown by a vapor growth method.

Title: Numerical controller
Inventor: NAKAHARA TSUTOMU
IPC: G05B19/404
Filed: 1988-12-02
Abstract: PURPOSE:To switch a servo signal on the user side by selecting a machine origin shifting variable and a pitch error correction independently in each type of the servo system through a positional detection switching part. CONSTITUTION:At the time of restoring operation to an origin, a servo motor 7 is driven in an origin restoring direction and decelerated by an origin decelerating signal, and in the case of a closed loop system, an origin signal outputted from a machine position detector 10 is detected. In the case of semi-closed loop system, an origin signal outputted from the detector 9 once per rotation of the motor 7 is detected. A machine origin position is determined by using the data of a shifted variable (a) or (b) from the detecting position up to the origin of the machine. At the time of receiving a positioning command other than the origin restoration, a pitch correction value corresponding to the closed loop system or the semi-closed loop system is selected to correct the pitch error of the machine. Thereby, the servo system can be switched on the user side.

Title: Image output method, image output device and image output medium
Inventor: KO HIROTETSU
IPC: H04N1/387
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To allow the user to visually recognize a watermark image through the observation by using a specific filter regardless of that the watermark image cannot be visually recognized through a conventional observation state by recoding an original 1st watermark image and a 2nd watermark image having nearly opposite characteristic to that of the 1st watermark image at spatially different positions. SOLUTION: A control section 10 controls each section. A watermark image processing section 20 receives a watermark image externally to generate a 1st watermark image and a 2nd watermark image, which have almost opposite characteristics to each other. A superimposing processing section 30 superimposes the 1st and 2nd watermark images and an external conventional image at a prescribed layout to generate an image with the watermark image information. An image output section such as a printer or a display device outputs the image with watermark image information or a filter.  Since the 1st watermark image and the 2nd watermark image with almost opposite characteristic to that of the 1st watermark image are recorded at spatially different positions, the watermark image cannot be visually recognized in the conventional observation state but the watermark image can be displayed by using a specific filter.

Title: Overtone piezoelectric crystal oscillator
Inventor: KOODO HAINRITSUHI KOOSHIIKU
IPC: H03B5/36
Filed: 1990-11-15
Abstract: PURPOSE: To unnecessitate an accurate adjustment of the resonance frequency of a resonance amplifier by satisfying a condition that the resonance frequency of the resonance amplifier exists between the frequency of a generated overtone and the succeeding lower oscillation frequency of a piezoelectric crystal oscillator. CONSTITUTION: The piezoelectric crystal oscillator has transistors(TRs) 1, 2, piezoelectric crystal 5, current sources 6, 7, TRs 11, 12, resistors 13, 14, 21, 22, capacitors 17, 19, 20, and a current source 18. The resonance frequency of the resonance amplifier exists between the frequency of a generated overtone and the succeeding lower oscillation frequency of the piezoelectric crystal oscillator and a signal in the frequency area of oscillation frequency lower than the frequency area of an overtone generated in a feedback loop, especially a signal from the resonance frequency, has phase shift suppressing the oscillation of the piezoelectric crystal oscillator at the succeeding lower oscillation frequency and generated only at the overtone frequency generated from the crystal oscillator.  Consequently the accurate adjustment of responance frequency of the resonance amplifier is made unnecessary.
