Title: Ultrasonic flaw detecting method
Inventor: MURAYAMA RIICHI
IPC: G01N29/04
Filed: 1982-07-21
Abstract: PURPOSE:To detect even an extremely small defect speedily with high precision, by specifying a flaw detection frequency and a flaw detection beam diameter, and scanning a probe with specific step width for flaw detection. CONSTITUTION:The probe 2 is provided over a material 1 to be tested dipped in water and the high-frequency ultrasonic wave beam of 30-100MHz reduced in beam diameter to <=0.3mm. is made incident to the material 1 to be tested through the water by the probe 2. The probe 2 is scanned in an X and a Y direction with <=0.2mm. step width (a) by a scanner controller 3 and the focal depth of the ultrasonic wave beam from the probe 2 is made coincident with a gate range preset depending upon the thickness of the material 1. An ultrasonic flaw detector 4 fetches a reflection echo into a minicomputer 5 at the same collection speed (b) with the step width (a) during the scanning of the probe 2, and only data within the focal depth range are transferred to a main computer 6 after distance and amplitude corrections to be displayed on a graphic display device 7.

Title: Mri image pickup method
Inventor: HAYANO YUICHI
IPC: G01R33/565
Filed: 1992-05-20
Abstract: PURPOSE:To eliminate an adverse influence exerted on a picture quality due to generation of a step difference of signal intensity, and to prevent a different contrast from being mixed in the contrast of an MRI image by adding such an offset phase gradient amount as a DC view becomes a view in the vicinity of the center of one block, to each phase gradient. CONSTITUTION:A (k) space (ksp) is constituted of 256 views, and each view is allowed to correspond to phases extending from -95*gws to +160*gws. It is executed by adding an offset phase gradient amount +32gws. Subsequently, the (k) space (ksp) is divided into four pieces of blocks b1, b2, b3 and b4 of continuous 64 views each, and as for plural primary to biquadratic echoes of an i-th time, they are collected by giving a phase gradient being large in a positive side to an i-th block in the respective blocks b1, b3, b3 and b4. By repeating it 64 times, data of a 256-view portion of the (k) space (ksp) is collected. In such a way, a step difference of signal intensity is not generated in a DC view.

Title: Production of phenol/formaldehyde resin
Inventor: KIMURA SHIYUUJI
IPC: C08G8/24
Filed: 1984-06-19
Abstract: PURPOSE:To obtain a phenol/formaldehyde resin which scarcely undergoes discoloration even after long-term preservation and storage, by condensing a phenol with formaldehyde in the presence of gallic acid. CONSTITUTION:In condensing a mono- or di-hydric phenol with formaldehyde, gallic acid is added to the reaction system, preferably in an amount of 0.1- 10pts.wt. per 100pts.wt. phenol. Addition of 10pts.wt. or above gallic acid causes discoloration in spite of its light-absorbing effect. Addition of 0.1pt.wt. or below gallic acid brings about no effect of addition. Said condensation is preferably carried out at a pH of 2.5-5. When the pH is above 5, the reaction rate of condensation is too low to obtain a desired effect. On the contrary, when it is below 2.5, the condensation is too violent to smoothly control the synthesis of a phenol/ formaldehyde resin.

IPC: H04N11/20
Filed: 1991-05-30
Abstract: PURPOSE:To reduce circuit scale by making common the field memory of a signal exchange circuit for converting the number of scan lines. CONSTITUTION:An output 110 from a mixer circuit 10 of a MUSE decoder is inputted to a D/D conversion circuit 15 of a standard television system conversion circuit 14. The signal 110 is converted by the circuit 15 and inputted to a selecting circuit 16. The circuit 16 selects a signal 116 during a luminance signal period and selects a signal 107 interpolated in a field during a chrominance signal period. Thus, a time division multiplexed signal with a vertical band 1125/4cph can be obtained. A signal 117 is inputted to a field memory 20 after limiting the vertical band through a prefilter 17. In such a case, an output signal 118 of the filter 17 is inputted to one terminal of a selecting circuit 19 and inputs it through a line memory 18 to the other input terminal. The circuit 19 inputs a signal 120 to the memory 20 while switching it at every two lines during a chrominance signal input period. Thus, two color difference signals can be written in the memory 20.

Filed: 1981-08-14
Abstract: PURPOSE:To obtain an injection molding machine of a compact form by a method in which a specific valve device having three openings is interposed between an injection cylinder and an oil-pressure switching valve for the injection cylinder. CONSTITUTION:A switching-constant pressure valve 23 is interposed between an oil-pressure switching valve 15 and injection cylinders 2, and the switching valve for controlling rotation and the switching valve for injection are used in common by flowing a slightly large flow rate of working oil fot the upper chamber of the injection cylinder 2 toward a rotation control switching valve 19 with a less allowable flow rate. A large flow rate of working oil from the lower chamber 7 of the injection cylinder 2 during the injection process is recovered in an oil tank 18 through the switching-constant pressure valve 23 by by-passing the oil- pressure switching valve 15. The switching-constant pressure valve 23 is incorporated with a check valve 40 and a constant pressure vlave in a coaxially integrated structure and its switching action is automatically performed by the flow of working oil.

Title: Dc high voltage device
Inventor: KIMURA TATSUO
IPC: H03K17/10
Filed: 1985-06-12
Abstract: PURPOSE:To slave-fire a semiconductor switch without providing a separate slave-firing capacitor by applying the charge stored in a capacitor of a smoothing column side of multi-stage rectifiers to the switch as trigger power. CONSTITUTION:When a trigger signal is applied to trigger terminals G1, G2, a semiconductor switch S1 is turned ON, and the charge stored in a capacitor C1 of a smoothing column side in multi-stage rectifiers 1 is discharged. Thus, a magnetic flux in response to the discharging current is generated in a ring core X1, and a trigger voltage is induced in a trigger winding Y1. The trigger voltage is applied between the gate and the cathode of a semiconductor switch S2 through a resistor r1. Thus, when the switch S2 is triggered to be turned ON, the capacitor C2 is similarly discharged. Thereafter, semiconductor switches S3, S4 are similarly slave-fired.

Abstract: PURPOSE:To perform selection of each nozzle hole so easily even during operation, by inserting a needle valve into the nozzle case inside provided with each nozzle hole for both low and high load uses, while selecting the moving blade installed in the nozzle case to reverse rotation with a solenoid selector valve. CONSTITUTION:When fuel is fed in from a fuel feed pipe 13, the fuel is spouted into an annular concave groove 10 inside a nozzle case 3 from a center hole 12a of an upper guide pipe 12, a center hole 9 and a tip nozzle hole 11 of a needle valve 8. If so, pressure inside this annular groove 10 goes up whereby the needle valve 8 is made to go up against compression springs 14 and 15. In consequence, the annular concave groove 10 and a center hole 3a of the nozzle case 3 are interconnected with each other so that fuel is spouted toward an opening 2 from a low load nozzle hole 5. On the other hand, when a solenoid selector valve 7 is selected to a B position, a hydraulic fluid enters a notch 18 from an oil passage 7b by way of a port 20, and acts on a moving blade, thereby rotating the nozzle case 3. Therefore, a high load nozzle hole 4 is opposed to the opening 2 face-to-face.
