Title: Protection structure of propulsion pipe coupling part
Inventor: MATSUYAMA EIJI
IPC: F16L57/00
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To provide the protection structure of the coupling part of a propulsion pipe. SOLUTION: A protection layer is prevented from damage due to contact with soil and sand and gravel in earth through the improvement of hardness of synthetic resin and by forming an adhesion end face part in a taper-form state, the change of a peripheral length owing to tolerance is regulatable. By point-symmetrically forming adhesion end faces on both the right and left sides, a two-division protection layer is formed by one and the same forms. A protection layer 1 is formed in a cylindrical shape and the coupling protection layer is longitudinally divided into half-sections and divided into 1a and 1b and formed of synthetic resin of which forms are molded by using a norbornene monomer having Shore hardness (D) of approximate 80 and a reaction solution containing a metathesis and an activated agent catalyst.  Adhesion end face parts 11a-11d with the two division protection layers 1a and 1b have respective tip part formed in a taper shape having width gradually decreased toward the tip. Adhesion end faces 4a and 4b on both the left and right sides are formed point- symmetrically about the center of a propulsion pipe 2.

Title: Bearing lubricating device
Inventor: KOBAYASHI YUJI
IPC: F16N7/36
Filed: 1986-01-27
Abstract: PURPOSE:To safely and reliably supply lubricating oil to a bearing by immersing an ultrasonic vibrator in a lubricating oil stored in a storage tank, and forcing the lubricating oil splashed by the vibrator to reach the bearing. CONSTITUTION:A storage tank 10 for lubricating oil 9 is formed at the lower portion of a sealed oil supply chamber 8 mounted on the side portion of a bearing 2 such as a pump or the like. A plate-like ultrasonic vibrator 11 is immersed in the oil 9 with a slight inclination in such a manner that the right end of the vibrator 11 is a little lowered. When the ultrasonic vibrator 11 is operated by a driving circuit 12, oil 9 above the vibrator is splashed upward and the column 9' of the splashed oil is inclined to the right because the vibrator is inclined. The oil is further moved along a guide plate 14 to drop on the forward end 13 of a rotary shaft. The forward end is conical, so that the oil is moved in the direction of an arrow P by centrifugal force to be supplied to the bearing 2. The bearing 2 may be directed vertically to the oil 9.

Title: Semiconductor integrated circuit
Inventor: YAMAZAKI TAKASHI
IPC: H01L21/82
Filed: 1986-01-24
Abstract: PURPOSE:To prevent insulating film breakdown by a method wherein a polycrystalline silicon film and metal film are formed on a semiconductor substrate and a diffusion layer opposite in conductivity to the semiconductor substrate, through the intermediary of an insulating film, and the diffusion layer is large enough to cover a polycrystalline silicon wiring, metal wiring, and polycrystalline silicon resistor. CONSTITUTION:A P-well 5 is formed on an N-type substrate 6 and thereon a fuse element.polycrystalline silicon resistor 2 is built with the intermediary of a silicon oxide film 4. Further, an Al electrode 1 is built through the intermediary of a silicon of a silicon oxide film 3 and a contact 7. In a circuit designed as such, with a diffusion layer lying just under a polycrystalline silicon resistor or a metal film through the intermediary of an insulating film, no short- circuiting occurs involving a substrate even in the presence of an insulating film breakdown because a short-circuiting occurs between the fuse element.polycrystalline silicon resistor and the diffusion layer isolated from the substrate by a junction. This realizes a fail-safe mechanism withstanding an interlayer insulating film breakdown.

Title: Scroll compressor
Inventor: WAKANA TATSUYA
IPC: F04C18/02
Filed: 1994-02-08
Abstract: PURPOSE:To reduce the noise at operation of a back pressure control valve by providing an interference material other than metal or a member having spring property between the needle of the needle valve and the needle presser in a back pressure control valve. CONSTITUTION:This back pressure control valve provided around a fixed scroll 2 is composed of a needle 21, a spring 24, a needle presser 25 working so that the needle 21 does not spring out, and an interference member 22 interposed between the needle 21 and the needle presser 25, and this controls discharge pressure 19, middle pressure 18, and suction pressure 17. That is, in case of normal operation (discharge pressure 19 spring force+middle pressure 18), the needle 21 is pressed down to close a middle pressure chamber and a suction chamber. On the other hand, in case that the pressure difference is small with low-speed operation (discharge pressure 19>spring force+middle pressure 18), the needle 21 is pushed up to connect the middle pressure chamber with the suction chamber, but at this time, in the upward and downward movement of the needle 21, noise is reduced by the contact with the interference material.

Abstract: PURPOSE: To obtain portamento effect tones by providing means of adding correction values to  the abovementioned change frequency information numerical values at specified timings and  forming new change frequency information numerical values.  
     CONSTITUTION: With the change frequency information numerical value F' being inputted to the  B input end of a subtractor 14 as a current value and the numerical value being inputted to the A  input end of the subtractor 14 as a target value FB, the value corresponding to the difference  between this target value FB and the current value F' is subsequently added as correction value to  the current value F' each time when portamento clock PCL is generated, whereby the current  value F' is subsequently changed. Such operation is repeatedly performed until the current value  F' coincides with the target value FB, i.e., until the value of the differntial signal outputted from  the subtractor 14 becomes zero, whereby the change frequency information numerical values F'  changing subsequently from the start value FA toward the target value Fa are formed and by  using these subsequently changing change frequency information numerical values F', the pitch  controlling of the musical tones being produced is accomplished.
