Title: Working device for cylinder
Inventor: ASHIZAWA YOSHIYA
IPC: B21D22/16
Filed: 1981-03-27
Abstract: PURPOSE:To save labor and increase productivity by trimming the end face of a formed product made by rotary ironing on a mandrel, and automating taking- out of products and waste materials. CONSTITUTION:The end face of a formed product 7 worked by rotary ironing using spinning rollers 9a, 9b is trimmed by a tool and separated into a product 7a and a waste material 7b. The product is then held by an extruding bar 6 and a tail stock bar 8 from both sides. The bars 6, 8 are moved to the right and the product 7a is extracted successively from a mandrel. To extract the waste material similarly at this time, a claw 14 is brought close to the mandrel 5 by action of a cylinder 15, and saddles 12a, 12b are moved to the right synchronously with the bars 6, 8 to push the end face of the waste material 7b by the claw 14. When the product 7a comes out from the mandrel 5, the waste material 7b also falls out. This is pressed by holding claws 17a, 17b. Then, the product 7a is held by a carrying claw 21, and the waste material 7b is held by a hook 19 being supported by a receiving stand. The product 7a and the waste material 7b are carried out after shifting of the bars 6, 8.

Title: Liquid level detector
Inventor: KATO AKIRA
IPC: G01F23/36
Filed: 1987-03-02
Abstract: PURPOSE:To continuously detect a liquid level and stabilize the lighting of a display unit by constructing a liquid level detector such that the liquid level is detected by a resistor and the display unit is lighted via a heating resistor and a thermistor. CONSTITUTION:Since a contact 10 for a slider slides on a resistor 8 when a liquid surface 2 changes while interlocking with the operation of a float 6, a liquid level can be continuously detected by taking out electric signals from change in the resistance value of the resistor. On the other hand, when the liquid level 2 reaches a prescribed position or below, the contact of the contact 10 for the slider is changed over from a contact 9b to a contact 9a. Therefore, a current flows from a power supply 3 to a heating resistor 11 to generate heat. The heat is transmitted to a thermistor 13 on the back of a substrate 7 therethrough. Since the electric resistance of the thermistor 13 is suddenly reduced when its temperature exceeds a prescribed value, a display unit 4 is lighted. At this time, though the liquid surface 2 is unstable, the lighting of the display unit 4 is stabilized by the delay effect of the heating action of the heating resistor 11 and heat transmitting action to the thermistor 13.

Title: Production of radical-polymerizable oligomer
Inventor: KUNUGIZA MOTOYASU
IPC: C08F299/02
Filed: 1979-04-16
Abstract: PURPOSE: To obtain an oligomer having low viscosity and good performance, and useful for paint, adhesive, reactive plasticizer, etc., by a method wherein phenol is reacted with an alkylene oxide to produce an adduct, and the adduct is reacted with a carbonyl cpd. and then with an unsaturated acid.  
     CONSTITUTION: Phenol or a derivative thereof (e.g. cresol) is reacted with an alkylene oxide (e.g. ethylene oxide) to produce an adduct. The adduct is reacted with a carbonyl cpd. (e.g. formaldehyde) to produce a novolak which is then esterified with an unsatured acid (e.g. maleic acid, or anhydride thereof) to obtain an oligomer which can be cured by a free-radical generating agent, heat, ultravoilet rays, or radiation.  
     EFFECT: The process has industrially an advantage in that novolak formation and esterification can be carried out in the same reaction kettle.

Title: Method for fixing light transparent parts
Inventor: HASHIMOTO MINORU
IPC: G02B7/00
Filed: 1994-03-16
Abstract: PURPOSE:To assure long-term reliability and to eliminate the influence of the shapes of light transparent parts by fixing a second hollow screw by screwing, then rotating a first hollow screw in a direction reverse from tightening and fixing the optical transparent parts in the state of removing the deformation stress by tightening of the optical transparent parts. CONSTITUTION:After the optical transparent parts 1 are inserted into a bottomed holder 2, the optical transparent parts 1 are tightened from an optical axial line direction by the first hollow screw 3 at the stress at which the shape deformation arises within an elastic threshold range. The second hollow screw 4 is then tightened up to fix the parts by screwing with the first hollow screw 3. The first hollow screw 3 is rotated in the direction backward from tightening until the optical transparent parts 1 deformed by tightening of the first hollow screw 3 restore the state before tightening of the first hollow screw 3 and thereafter, the parts are fixed, by which the optical transparent parts 1 are fixed in the state free from the shape deformation. In addition, the loosening of the screw 3 is prevented by rotation of the first hollow screw 3 in the direction backward from tightening.

Abstract: PURPOSE:To prevent a, reflection light giving a damage to all optical part by composing a beam pattern forming means by contg. the reflection film having the profile correcting the profile of the corresponding pattern in one direction and providing a heat sink at the rear part of the reflection film. CONSTITUTION:The laser light emitted from a laser device 1 is made incident on an optical fiber 3 from an incident lens 2, returned to a parallel beam by a collimation lens 4 and fed to an image forming lens 6 by being reflected in about orthogonal direction by the reflection mirror 5 having a reflection film 5a. The laser beam reflected in the orthogonal direction by the reflection film 5a becomes that multiplying the magnification by the necessary mark in the optical axial direction of the lens 6. On the other hand the substrate 5b of the reflection mirror 5 uses a transparent material for the laser light, so the residual laser light not reflected by the reflection film 5a is passed through the substrate 5b, absorbed by a heat sink 8 and radiated by changing into a heat.

Abstract: PURPOSE:To obtain high-speed operation and a fine wiring structure by using a photoresist pattern in which an aluminum wiring occupation area is made to be substantially of a specific value of the whole wafer area for etching an aluminum film. CONSTITUTION:After forming a silicon nitride film 2, which is an insulating film, on a silicon substrate 1, while being covered with an aluminum 31, a pattern of a photoresist 4 is formed.
