Title: Wire slackness detector of multilayer winding drum
Inventor: FURUDONO HIDEYUKI
IPC: B66D1/36
Filed: 1977-12-29
Abstract: PURPOSE: To keep this detector to an outer surface of a wire of a drum at an approx. fixed interval, by varying a location of a wire slackness detecting portion material to a winding wire while interlocking the location with the variation of a pinch roller.  
     CONSTITUTION: Gears 3, 4 arranging an interlocking mechanism are engaged with a lever base terminal portion 1b of a pinch roller 1. Levers 5, 6 fastened to the gears 4 are unified, and an angle formed between both levers is unchangeable. When a wire 11 is loosened, a limit switch 16 is operated because a wire slackness detecting portion material 12 turns against the force of a spring 15 by the tare of the wire 11, the slackness of the wire 11 is automatically detected and a motor for driving a winch is stopped. When the winding layer of the wire 11 increases, the pinch roller 1 is turn displaced in the clockwise rotation direction while compressing a spring 9, the wire slackness detecting portion material 12 is turn displaced in the counter- clockwise rotation direction and a nose of a lever portion 12a is kept to an outer surface of the wire 11 at a fixed interval S.

Title: Magnetic head
Inventor: FUJITA TAKESHI
IPC: G11B5/265
Filed: 1983-08-31
Abstract: PURPOSE:To obtain a magnetic head of a flexible disk device which can increase the glass adhesion intensity by forming a glass sink on the adhesion surface of both sliders by providing a vertical or horizontal slit having a bottom which prevents the flow of the fused glass at the upper part of the core adhesion surface of sliders at both sides. CONSTITUTION:Slits 20 and 21 are formed to slider parts 1' and 5' respectively, and parts 1'-5' are laminated by means of a tool. Then glass rods are put into the slits 20 and 21 and adhered in a furnace of a high temperature. In this case, the fused glass does not flow out but stays in a hollow part formed with parts 2'-4'. Thus these parts 1', 5' and core parts 2'-4' can be adhered together with a sufficient amount of glass. In such a way, the highly intensive adhesion is secured for the parts which are laminated close to each other with high accuracy.

Title: Frequency converter
Inventor: YAMAJI TAKAFUMI
IPC: H03D7/00
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To obtain a frequency converter, capable of obtaining a desired receiving characteristic with little consumption current by providing a frequency conversion circuit performing a frequency conversion and a buffer amplifier circuit which has a low-pass characteristic of a cutoff frequency which is higher than a desired signal frequency band and lower than an adjacent channel carrier frequency. SOLUTION: This frequency converter consists of a frequency conversion circuit 11 and a buffer amplifier circuit 12. A local oscillation signal is inputted to a terminal L0 of the circuit 11, and a high-frequency signal is inputted to a terminal RF. However, because the circuit 12 has to amplify a desired signal, the cutoff signal of this circuit has to be higher than a desired signal frequency band. However, it has to make the cutoff frequency of the circuit 12 smaller than the carrier frequency of an adjacent channel to eliminate the signal of the adjacent channel and to amplify it. In this way since an unwanted signal does not have to be amplified any longer by performing band limitation, it is possible to reduce consumption current.

Abstract: PURPOSE:To prevent the malfunction by prohibiting the second push button from being depressed without the preaction to depress the first push button and prohibiting only the first push button from being protruded by a return spring with both the first and second push buttons kept depressed. CONSTITUTION:When both switches (a), (b) are set off, push buttons 1-4 are protruded by a return spring 6. If the second push button 2 is intended to be depressed at this time, one piece 15 of the first lever 13 is coupled with a coupling recess 2a-1 with no sliding face, thus the second push button 2 can not be depressed first. When both the first and second push buttons 1, 2 are depressed to set the switches (a), (b) on, the other end 21 of a moving bar 18 is coupled with a coupling recess 4a-2 with no sliding face of the fourth push button 4 and looked, thus the first push button 1 can not be returned to the off position by depressing the fourth push button, i.e., the first push button 1 can not be returned to the off position with only the second push button kept at the on position. The malfunction at the time of closing or opening a circuit is thereby prevented.
