Title: Tracking control method
Inventor: TSUJI TAKAO
IPC: G11B7/09
Filed: 1983-02-02
Abstract: PURPOSE:To reproduce information consisting of a desired signal train by holding a tracking error signal, and leading out this tracking error signal if a drop- out occurs to a reproduced signal to perform tracking. CONSTITUTION:An optical system operates to reproduce on a signal sequence 13a on a recording medium 13, and at the same time, a tracking error signal generator 17 generates the tracking error signal which shows the deviation of a relfected light beam from the signal sequence 13a due to eccentricity, etc., from the reproduced signal of a photodetector. A signal holding circuit 18 outputs the tracking error signal while holding it all the time. If foreign matter sticks onto the signal sequence 13a during this tracking, a drop-out detector 20 detects absence of the reproduced signal, i.e. drop-out to generate a drop-out signal, and the tracking error signal which is held in the signal holding circuit 18 and a fine time before the drop-out occurrence is outputted to a mirror driver 8 while the drop-out continues, controlling a tracking mirror correctly.

Title: Multi-spindle boring tooling commonly used for two kinds of workpiece
Inventor: MATSUSHITA KENJI
IPC: B23B39/16
Filed: 1987-01-24
Abstract: PURPOSE:To make it possible to reduce the number of spindles and to reduce the limitation to the number of spindles to be attached, by enabling a spindle head mounted in a spindle head casing to rotate so that one of workpieces of one and the same kind which is reversed in its attitude is bored by rotating the spindle head. CONSTITUTION:When a workpiece W1 is turned by an angle of 180 deg. and is introduced with the attitude as indicated by W2, the kind of the workpiece is discriminated in accordance with the positional relationship between a temporary workpiece receiving bed and a tool 4, and spindle heads 2, 5, and spindle heads 2, 5 are turned by an angle of 180 deg. so as to machine the workpiece in accordance with a signal indicating the discrimination. Further, when the workpieces W1, W2 are alternately transferred, the spindle heads 2, 5 are mounted on a spindle head casing 1 in such a condition they are previously shifted by an angle of 180 deg., and both spindle heads are simultaneously rotated in association with the transfer of the workpiece to bore and chamfer the workpieces. Thus, even though a workpiece is turned up side down, the machining may be made by only one row of tools while the number of spindles are reduced to one half of that of the conventional one, and further, it is possible to mount a row of tools for different kinds of workpieces, thereby it is possible to enhance the productivity.

Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To make directly sterilizable a liquid by eluting silver ions to the liquid in a moderate proportion by sterilizing the liquid by keeping a silver oxide powder in floating state in the liquid and eluting the silver ions to the liquid while the liquid to be sterilized is passed. SOLUTION: The silver oxide powder is kept in floating state in a flowing liquid. In this case, the silver oxide power is housed in a liquid permeable housing body, for example a bag of a texture having a fixed mesh, and the powder is immersed in the liquid together with the housing body in order to keep the silver oxide powder in the floating state. And the silver oxide powder is constituted with the primary particles having >=8 micron and/or <=25 micron particle size, moreover, the power is crystalline favorably. An eluting property to the liquid and a durability of the elution of the silver oxide powder are kept moderately by using such a powder, and also the elution of the silver oxide powder itself out of the housing body is prevented by using the liquid permeable housing body having a moderate mesh.

Abstract: PURPOSE:To make it possible to perform accurate position control by a milli- meter unit by setting a pitch (p)mm of a toothed belt X the number of a drive pulley (n)/an objective minimum travel amount (s)mm so as to become a nearly integral number in a device converting a motor revolution to linear motion by a milli-meter unit by the use of a tooth belt pitched in inch and by detecting the rotational position of a motor by a position detecting means outputting pulses of (p)X(n)/(s) per one revolution. CONSTITUTION:In an industrial robot, when (p)mm is taken as pitch of a toothed belt 18 for driving a slider 20, (n) is taken as the number of teeth of a drive pulley, and (s)mm is taken as an objective minimum travel amount, each of them is set so that the result of (p)X(n)/(s) may become a nearly integral number. And the rotational position of a motor 24 for driving a drive pulley 14 is detected by a rotary encoder 26 for outputting same number of pulses as (p)X(n)/(s) per one revolution. And the servo motor 24 is controlled on the basis of the difference between the output pulse (b) and commanded travel quantity through a counter 28, D/A 30, and a driver 32. The linear position control by the milli-meter unit can thus become possible by using the toothed belt pitched in inch.
