Title: Manufacture of mask plate
Inventor: YAMAZAKI KEIZOU
IPC: G03F1/60
Filed: 1983-03-22
Abstract: PURPOSE:To eliminate the need to grind scraps off a device and the guide surface of a jig and to obtain an easy-to-handle mask plate by dipping a chamfered part in a corroding solution and smoothing it. CONSTITUTION:The chamfered part of the mask plate 1 is worked with abrasive grains of #400-600, so the surface has ruggedness of several tens micron and its shape is extremely sharp. This glass plate is dipped in the corroding solution of hydrogen fluoride to round fine sharp ruggedness of the chamfered part. When the corrosion is carried out between chamfering and the polishing of a glass surface, the whole glass plate is dipped in the corroding solution, so the operation is facilitated. Processes other than the process of dipping the glass plate in the corroding solution may be the same as normal mask plate manufacturing processes. The use of this mask plate eliminates the need to grind the device and guide surface of the jig and the easy-to-handle photomask of high quality is obtained.

Title: Method of making leather fiber
Inventor: OKABE TOKIAKI
IPC: B02C19/18
Filed: 1979-04-16
Abstract: PURPOSE: To dried waste of leather is divided into fibers under specific conditions and long fiber part is made into fine and complex fibers, thus producing said leather fiber suitable used for boards, sheets and leathers because of its good surface properties and touch feeling.  
     CONSTITUTION: After leather wastes such as shaving waste or end cut waste are dired to 20W40% water content, they are cut with sharp cutters into fine strip to give the secondary manufactured material. The material is stirred together with water and the water content of the material is adjusted to some 50W70%. At this time, when the pH is controlled to 6.5W7 by adding aqueous sodium bicarbonate, the dyeing property is increased. The product is milled into fibrous material to give the third material. The resulting material is dried to less than 40% water content, beaten, sieved and selected to collect long fiber parts. The long fibers are, further, milled into split fibers, simultaneously scraped to form fiber elements and fibrils, resulting is giving cotton-like appearance by fiber's complicated bending and flexing.

Title: Rotary encoder
Inventor: IIJIMA KENZABURO
IPC: G01D5/245
Filed: 1986-03-05
Abstract: PURPOSE:To make an output signal stable by tracing a magnetic recording medium and a base plate for a magneto-resistance element provided coaxially to one and the same shaft in response to the fluctuation of the shaft so as to always keep the gap between the magnetic recording medium and the magneto-resistance element constant. CONSTITUTION:The base plate 5 is not driven with a shaft 2 but moved incorporatedly with the shaft 2 with respect to the vertical direction. Further, the tip of a rod 8 is fitted to a recess 7 to lock the base plate 5 to a housing 1. If the shaft 2 is fluctuated vertically, both the magnetic recording medium 3 and the base plate 5 are displaced incorporatedly with the shaft 2. Since the relation of position between the medium 3 and the base plate 5 in the vertical direction is unchanged, the gap between the medium 3 and the magneto- resistance element 4 is not fluctuated. Thus, the output is made stable regardless of the fluctuation of the shaft 2.
