Title: Work positioning device for cutting machine
Inventor: KOUZUKI HIDEMASA
IPC: B23Q3/18
Filed: 1979-06-28
Abstract: PURPOSE: To provide a positioning device for improving the machining precision by a method wherein the final centering of the work can be conducted by a cutting tool on a spindle, in a reaming machine for valve guides of engines.  
     CONSTITUTION: A floating slider 9 mounted on the work 5 is set in a floating condition. Keeping this condition, a bush 14 for temporary positioning is moved upwards to cause an opening portion at its tip end to fit to the tip end of a valve guide 6, and temporary positioning is conducted by the bush 14. Next, a guide portion for positioning of the first cutting tool 3 is inserted into the valve guide 6 and the bush 14 is lowered. In this case, though the work 5 is centered by the cutting tool 3 and slightly moved relative to the centering position of the bush 14, this movement is largely smoothed by the floating slider 9. Then, with the pneumative pressure of the slider 9 being cut off, the work is clamped by a clamping device, and the inside diameter portion of the valve guide 6 is machined by the first cutting tool 3.

Title: Optical information recording and reproducing device
Inventor: OKAZAKI YUKINORI
IPC: G11B7/00
Filed: 1988-03-31
Abstract: PURPOSE:To improve recording and reproducing precision by obtaining reflected light beams of same strength distribution not only from an area where information is recorded but also from unrecorded area, detecting the tilt quantity of a disk substrate and controlling the position of an optical head so that recording and reproducing light beams are always made incident vertically on a disk. CONSTITUTION:A light source for tilt detection 14 and a photodetector 15 detecting the reflected light beams from the disk 11 are provided on the same mobile base 13 as the optical head 12 which moves from the inner peripheral side of the disk 11 to an outer peripheral side. Light beams emitted from the light source 14 are made incident on the disk 11 while making them in the same direction as the light beams emitted from the head 12, and the light beams are reflected in the different positions of the photodetector 15 in accordance with the tilt of the disk 11. Since a signal obtained from the photodetector 15 turns into a signal in which the tilt of the substrate 11 is reflected, the whole optical head mobile base 13 is accordingly tilted together with the disk substrate 17 by using a motor 16. At that time, the wavelengths of the light beams used for the head and those of the light source 14 are made different, and the detection of the inclination is stabilized.

Title: Antimicrobial or repellent molding and its production
Inventor: MORIKAWA TOSHIYUKI
IPC: A01N25/34
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To obtain a new antimicrobial or repellent molding that has high degree of safety, excellent antimicrobial performance or repellency, and capability of retaining effects over a long period of time by combination of a compound having antimicrobial or repellent effects with a specific compound. SOLUTION: This antimicrobial or repellent molding comprises a compound having antimicrobial or repellent property (preferably a terpene compound) and calcium hydroxide. This molding is obtained by mixing the antimicrobial or repellent compound, calcium oxide and water. The calcium oxide easily reacts with water by exothermic hydration to form calcium hydroxide. If in this hydration an antimicrobial or repellent compound coexists, the compound is absorbed to and retained on the calcium hydroxide. At this time, if the proportions of the antimicrobial or repellent compound, calcium oxide and water are optimized, the antimicrobial or repellent compound can be completely captured in capsules having a shell composed of calcium hydroxide.
