IPC: G03F7/20
Filed: 1990-10-12
Abstract: PURPOSE:To prevent the film for a mask from shifting in position from a multi-layered printed board at the time of air discharge by forming air outlets diagonally in the fixed base of an exposing machine where the multi-layered printed board is fixed and forming many opening parts for air discharge in the center part of the film for the mask at positions where a pattern for exposure is not affected. CONSTITUTION:The air outlets 9 are formed diagonally in the fixed base 8 of the exposing machine where the multi-layered printed board 1 and the air at the peripheral part of the multi-layered printed board 1 coated with a transparent film 6 is discharged in a uniform direction. Many opening parts 11 for air discharge are formed in the center part of the film 3 for the mask where the exposure pattern is not affected and the air between the film 3 for the mask and multi-layered printed board 1 is discharged through the opening parts 11. Consequently, the mask film 3 does not move and never shifts in position from the multi-layered printed board 1. A plate member 12 made of rubber is arranged between a frame-shaped member 7 and the multi-layered printed board 1 and the surfaces of the transparent film 6 and frame- shaped member 7 are set in the same level to prevent the deflection of the transparent film 6, thereby performing exposure with high accuracy.

Title: Semiconductor substrate film thickness measuring method and manufacturing semiconductor substrate
Inventor: SUZUKI TAKAMASA
IPC: G01B15/02
Filed: 1996-10-17
Abstract: PROBLEM TO BE SOLVED: To measure thickness of a second conductivity type layer on a first conductivity type layer formed on a semiconductor substrate. SOLUTION: In a vessel contg. a hydrofluoric acid soln. an SiC substrate 100' is dipped and an ultraviolet ray is irradiated on a p-n junction of the substrate to generate a photoelectromotive force in the substrate, thereby electrolyzing the soln. into H ions and F ions. Since the F ions are more produced than the H ions, a p-type epitaxial layer 3 is etched at a higher rate than that of an n<+> type semiconductor substrate 1 and n<-> type epitaxial layer 2. SEM observation of the p-n junction face indicates a black-white contrast at the boundary between the epitaxial layers 3, 2. Thus the thickness of the epitaxial layer 3 can be measured.

Abstract: PROBLEM TO BE SOLVED: To shorten a recognition processing time and to improve a recognition rate by scanning musical score image data at right angles to the five staffs, and finding the line width and intervals of the five staffs from pixel length frequency distribution data and calculating resolution and/or density. SOLUTION: A scanner 12 optically scans a musical score and generates binary or gray-scale image data, and the read image information is inputted to a RAM 3 or HDD 4 through a scanner interface circuit 13. Here, the music scale image is scanned at right angles to the five staffs to find the length of successive white or black pixels, and frequency distribution data by the length are generated. The line width and intervals of the five staffs are found from this frequency distribution data, the resolution and/or density of the inputted musical score image data are calculated from the found line width and intervals, and the picture quality information is displayed on a CRT 6. Consequently, when the resolution and density of the musical score image data are not within a range required for recognition, they are displayed and image data can be taken in again.

Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To perform flow rate measuring having high resolution based on accurate time measuring by adjusting delay time and a transmission cycle based on the cycle of an asynchronous oscillation circuit and obtaining highly reproducible delay time and transmission cycle. SOLUTION: A signal received by a vibrator 11B is amplified and compared with a reference signal by a comparator circuit 14 and, when a signal exceeding the reference signal is detected, the signal is delayed by a delaying means 16 and then an ultrasonic wave signal is transmitted repeatedly by a set number of times by a repeating means 15. At this time, the delaying means 16 integrates the signal of a roughly constant cycle oscillated by an asynchronous oscillation circuit 16A by a delay counter 16B so as to set delay time. Then, time when the repeated transmission of the ultrasonic wave signal by the set number of times is finished is measured.  Then, the transmitting/receiving of first and second vibrators 11A and 11B is switched, time for repeatedly propagating the ultrasonic wave signal from the vibrator 11B to the vibrator 11A (from downstream side to upstream side) is measured, and by a flow rate calculating means 20, the value of a flow rate is calculated from a time difference by considering the size and the flowing state of a fluid pipe route 10.

Title: Oscillation circuit
Inventor: ONO KAZUNORI
IPC: H03K3/0231
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To stabilize a charging/discharging operation to be stable independently of the fluctuation of a power source voltage by providing a current supply source which is functioned as a constant current source for temp. change and is propotionated to the fluctuation of the power source voltage for the fluctuation of supply voltage and controlling charging/discharging current. SOLUTION: The output of an operational amplifier 201 is transmitted to the gate of NTr 202 and the source terminal output of NTr 202 becomes a negative feedback voltage to the reverse input terminal of the operational amplifier 201. Current I0 permitted to flow in PTr is expressed an expression (number 10) and I0 changes only by relying on the power source voltage VDD regardless of the change of an element characteristic by the temp. change of NTr 202. Then, in a current switch part 103, the charging/discharging current IC1 and IC2 rely on charging/discharging control current which is decided by the output voltage of a current source part 101.  Therefore, since the current source part 101 is functioned as the constant current source as against temp. change, a normally stable oscillation frequency is obtained without depending on the change of the element characteristic owing to temp. change.

Abstract: PURPOSE:To obtain a writing utensil reduced in the number of parts and also easy to assemble by making it possible to allow the leading end writing member of a writing body to protrude and recede through the leading end opening part of a main body by moving a push-out piece before and behind by the operation on this side. CONSTITUTION:When a finger is slightly shifted rearwardly while a shaft cylinder 1 is gripped to allow a push-out piece 6 to advance, a hook part 6c is hooked with the step part 1e of the shaft cylinder 1 to be engaged therewith and a leading end writing part 7c becomes a protruding state. When writing is carried out in this state, the writing pressure applied to the leading end writing part 7c of a writing body 7 is applied to a receiving part 4 at first by an engaging part 7a and successively applied to the connection body 5 and push piece 6 integrated with the receiving part 4 and finally applied to the engaging part of the hook part 6c of the push-out piece 6 and the front step part 1e of the shaft cylinder 1. When the thin wall part 6b of the rear end of the push-out piece is further lightly pushed in the diameter direction by a finger, the hook part 6c is raised to be released from the engagement with the step part 1e and, therefore, the writing body 7, the receiving part 4, the connection body 5 and the push-out piece 6 recede by the force of a spring to return to a writing body receiving state. By this constitution, the number of parts are reduced and assembling becomes easy.
