Title: High-water/cement ratio type pile head treatment work
Inventor: AIDA JUNRO
IPC: E02D5/34
Filed: 1985-11-15
Abstract: PURPOSE:To make the chipping operation of pile head easier as well as reduce the occurrence of noise and vibration by a method in which an aqueous solution of a viscous high molecular compound is added to and mixed with the extra- banking portion of the heat of a concrete pile to lower the setting property of concrete in the extra-banking portion. CONSTITUTION:Concrete 1 for in-situ pile is placed, and then water mixed with a viscous high molecular compound is injected into the concrete 1. The amount of the high molecular compound to be added is controlled to 0.1-5.0% of the weight of water. When they are mixed while turning a propeller-shaped mixer 2, the concrete 1a of the extra-banking portion becomes of much lower strength. The pile head treating operation is ended by partly using a motor driven pick. The needs for breaker or compressor can thus be eliminated, and the total cost for treating the pile head can be greatly curtailed.

Title: Au-sn brazing filler metal
Inventor: KOMATA MASASHI
IPC: B23K35/30
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to produce a brazing filler metal having a desired wire size and a granular brazing filler metal having desired mass by forming an Au-Sn brazing filler metal of a compsn. contg. 12 to 37wt.% Sn and controlling this brazing filler metal to a temp. of a prescribed range. SOLUTION: An Au-Sn allay added with 12 to 37wt.% Sn is controlled to 190 to 270 deg.C, by which the production of the wire-shaped brazing filler metal by warm extruding and warm drawing and the granular brazing filler metal of the desired mass by warm cutting is made possible. Malleability is insufficient and working is not possible at the temp. below 190 deg.C. The brazing filler metal rises to a temp. near its m.p. at the temp. exceeding 270 deg.C and, therefore, the crystal grains are coarsened and the deterioration of the material arises. The reason why the Sn is confined to 12 to 37wt.% lies in that hot working is proven to be made possible by temp. control.

Title: Ultrasonic treatment apparatus
Inventor: KUBOTA TATSUYA
IPC: A61B17/22
Filed: 1987-10-13
Abstract: PURPOSE:To prevent the amplitude of ultrasonic vibration of a tip of a vibration transmission member from greatly reduced and perform treatment for crushing stones, etc., positively and quickly, by giving a treated part slight movement periodically. CONSTITUTION:A supersonic treatment apparatus consists of a sheath 2 to be inserted into the body cavity in the course of treatment and an operation part 3 to perform various operation for treatment. An optical fiber tube of an endoscope is inserted in the sheath 2. A base 8 for fixing the treatment part included in the operation part is mounted with a handle part 10 of the treatment part 12 composed of a transmission part 11 consisting of the handle part 10 with a built-in ultrasonic vibrator and a vibration transmission member. The handle part 10 and the transmission part 11 have slight movement periodically caused by reciprocating motion of a piston 15. By manual operation of the operation part 3, a tip 11a is projected out of the sheath 2, and applied to an affected part 18 to give ultrasonic vibration. The treatment is further given a slight movement. Accordingly neither the tip 11a of the vibration transmission member remains applied to the affected part 18, nor the amplitude of ultrasonic vibration is greatly reduced.

Title: Method and apparatus for evaluating thermal stress distribution of specimen using ultrasonic tomography
Inventor: AMADA SHIGETSUGU
IPC: G01N29/22
Filed: 1988-10-13
Abstract: PURPOSE:To make it possible to evaluate a heat resisting material by generating ultrasonic waves having wide directivity from one point on the surface of a specimen, obtaining the propagating speeds of the ultrasonic waves to receiving points based on the transmitting times of the ultrasonic waves, and obtaining the temperature of each region. CONSTITUTION:For example, when nonuniform temperature distribution is present only in the plate thickness direction (X axis) in an infinite plate having the equal thickness, laser pulses having minute spot diameters are projected on the left end. Then ultrasonic waves are generated at the projected parts by the thermal elasticity effect. The ultrasonic waves are received with receives at points S (S1-SN) at the right end. Then the propagating times of the ultrasonix waves can be measured along paths L (L1-LN). The distribution of the propagating speeds of the ultrasonic waves can be obtained based on the measured times by specified expressions. Then the temperature distribution is obtained based on the propagating speeds. Finally, the thermal stress distribution is obtained. In this way, a heat resisting material can be evaluated, and the breakdown due to the thermal stress can be evaluated.

Abstract: PROBLEM TO BE SOLVED: To dispense with a key lock of complicated construction and enable two pieces or more latch locks to be fitted by fixing one end of a wire rope to a first latch lock, winding the center part around a shaft provided on the center of an outer facing door, and fixing the other end to a second latch lock through the shaft. SOLUTION: A shaft 4 is provided on the center of an outer facing door 6 so as to be held with a metal fitting 10, one end of a wire rope 3 is wound to a latch lock 2 fitted to the one end of the outer facing door 6, the center part is wound around the shaft 4, and the other end is fixed to a second latch lock through the shaft 4. The door in the locked state pulls the lock part 8 of the latch lock 2 through the wire rope 3 by rotating the shaft 4, detaches the lock part 8 from a lock bracket 9, and hence the outer facing door 6 becomes in the unlocked state. Because a plurality of wire ropes can be set on the optional places of the shaft 4, this mechanism can deal with even the case in which the outer facing door 6 is large-sized and many latch locks 2 are required.

Title: Saw tooth wave generator and convergence correcting device using the generator
Inventor: BEPPU TAKEYOSHI
IPC: H03K4/501
Filed: 1988-10-13
Abstract: PURPOSE:To attain correct convergence by switching and outputting a saw tooth wave corresponding to a trigger pulse and a voltage corresponding to the output of a peak detecting circuit to obtain a synthesized signal. CONSTITUTION:When a vertical trigger pulse is impressed to an input terminal 10, a discharge transistor(TR) 11 is turned off during the 'L' level period of the vertical trigger pulse, the voltage of the upper end B of a charging/ discharging capacitor 13 is gradually boosted, and in the 'H' level period, the capacitor 13 suddently discharges electricity. Thereby, a saw tooth wave can be obtained at a point B, level shifted by a level shifting circuit 14, detected at its peak by a peak detecting capacitor 18, and converted into a DC voltage. A saw tooth wave obtained at a point G and the voltage of a point F are impressed to a switching circuit 23 and the circuit 23 switches and outputs the saw tooth wave signals and the voltage in accordance with the vertical trigger pulse. Consequently, convergence correction can be accurately executed.

Title: Image forming device
Inventor: NIITSUMA TETSUYA
IPC: H04N1/29
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To obtain a back-surface image formed by performing transfer actions twice without causing blurring like a front-surface image formed by one transfer action by making a back-surface image processing method different from a front-surface image processing method so that high-pass emphasis is executed in the case of the back-surface image processing in comparison with the front- surface image processing method. SOLUTION: The image is processed by an image processing part by receiving an instruction from a control part B10. By the control part B10, it is judged based on information from a front/back surface decision means B20 whether image data outputted from the decision means B20 is used for the front-surface image or the back-surface image when the image is formed. When the image data outputted from a memory B14 is used for the back surface, the high-pass emphasis is executed in comparison with the front surface when the back-surface image is processed. By executing the high-pass emphasis, the conventional blurring edge part of a toner image obtained by performing transfer actions twice is emphasized and made clear. Thus, the blurring is reduced and the back- surface image is observed as the image being similar to the front-surface image.
