Title: Magnetic recording and reproducing device
Inventor: MINAMI EIJI
IPC: G11B15/02
Filed: 1982-03-12
Abstract: PURPOSE:To detect intermusic gaps without reference to a tape speed, by arranging two heads at an internal shorter than the length between pieces of music on a tape, finding the tape speed from their outputs, and detecting intermusic gaps from a time difference corresponding to the speed of the tape. CONSTITUTION:For the tape 1 running as shown by an arrow 12, the heads 4 and 5 are provided at the interval shorter than the intermusic distance. The outputs of the heads 4 and 5 are inputted to a time difference detecting part 10 and detecting circuits 8 and 8' through waveform conversion parts 9 and 9'. The time difference detection part 10 finds the speed of the tape 1 from the time difference between the waveform converting circuits 9 and 9' to control response characteristics of the detecting circuits 8 and 8'. By the outputs of the detecting circuits 8 and 8', a command is supplied to a control circuit which is not shown in a figure to perform switching between a normal sound recording and reproducing mode and a stop mode. Thus, intermusic gaps are detected accurately without reference to the speed of the tape 1. During the backward run, they are detected similarly.

Title: Plasterboard and its production
Inventor: HANADA KOZO
IPC: C04B41/50
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To obtain a plasterboard excellent in resistances to both impact and abrasion by applying water-glass to the surface of a plasterboard made up of hemihydrate gypsum and then hardening it. SOLUTION: This plasterboard is obtained by heating a board made up of hemihydrate in the temperature range of 50-500 deg.C and then applying water- glass to its surface through spraying, brushing, dipping, etc., followed by removing water included in the water-glass with heat due to the above heat-treatment to harden the water-glass and form a surface layer made of the water-glass on the surface of the board made up of hemihydrate. The surface layer made of the water-glass improved resistances to both impact and abrasion in comparison with a layer coated with a synthetic resin. If necessary, it is also possible to obtain a plasterboard excellent in design as well as in resistance to both impact and abrasion by blending a colorant with the water-glass.

Title: Rubber milling method and rubber composition prepared by the method
Inventor: FUJITA KYOZO
IPC: C08C1/00
Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To provide a rubber milling method which can impart excellent lubricating effect and improve the working efficiency of the step of rubber milling by adding a small amt. of a fatty acid amide to a compounded stock and conducting milling. SOLUTION: A fatty acid amide (e.g. an oleic acid amide) in an amt. of 0.5 to 5 pts.wt., together with various compounding chemicals, is added to a compounded stock, followed by milling. This causes the fatty acid amide to be incorporated into the rubber, and a given amount thereof is oozed out onto the surface of the rubber and serves as a kind of a lubricant. Therefore, this method prevents the rubber from adhering to a mixer or a roll, improves the slippage, and improves the work efficiency. Use of a butyl rubber as the raw rubber enhances the effect attained by the addition of the fatty acid amide. The added fatty acid amide is contained in the milled stock and the semifinished or finished product to be molded, and the presence of the fatty acid amide can offer an auxiliary effect that the molding is facilitated and the resultant product can enhance the lubricity.

Abstract: PURPOSE:To process lots of communication with a few number of lines and small sized installation by applying complementary variable control to the number of reception/transmission channels baseed on the number of times of reception per unit time, and applying variable control to an incoming trunk number. CONSTITUTION:The number of reception channel sections 2b and transmission channel sections 2a is subject to complementary variable control based on the number of times of reception per unit time in a reception frequency measuring means 7 and the number of incoming trunks is subject to variable control in interlocking with the number of set channel sections 2b by sending a control signal from a control data generating section 75 to a channel control section 5 and an incoming trunk control section 6. Thus, when the number of times of reception is increased due to the increased communication request from a facsimile equipment 20, the number of assignment of the channel sections 2b and the incoming trunks is increased. On the other hand, when the quantity of communication is less, the number of assignment is reduced and the setting number of the channel sections 2a instead and the stored picture information is sent quickly.
