Filed: 1995-06-07
Abstract: PURPOSE: To provide an inexpensive structure with which the deformation of a cable juncture housing body is prevented, safety and hermeticity are enhanced and assembly workability is greatly improved. CONSTITUTION: A cylindrical case 2 enclosing the circumference of the optical cable juncture 1 is freely expandably constituted by having a hinge part 3 embedded in an axial direction and divided end edges 4, 4 disposed to face this hinge part 3. Side wall parts 5 are integrally formed at both end faces of the cylinder case 2 and end faces sealing member 6 to be fitted and inserted with the cable are freely attachably and detachably fitted and disposed at the central parts of the side wall parts 5. Both end edges of the cylinder case 2 are fitted and disposed at a bottom plate 7 and end face sealing members 6 are attached and held in the cylindrical case 2.  As a result, the extremely rapid execution of the work to cover and house the cable juncture is made possible and the hermetic sealing of high reliability is assured by compressing the sleeve uniformly over the entire periphery at the few tightening points. In addition, the posture of the case is stabilized by omission of end face plate.

Title: Piezoelectric type pressure detector
Inventor: URASHIMA TOSHIYOSHI
IPC: G01L23/10
Filed: 1988-06-29
Abstract: PURPOSE:To improve linearily in pressure sensitivity by providing a planar sintered hard alloy part whose area is larger than a contact area for a piezoelectric element between at least one of a case or a diaphragm and the piezoelectric element. CONSTITUTION:Planar sintered hard alloy parts 10 having the thickness of about 1-2mm are provided between a piezoelectric element 5 and a case 1 and between the element 5 and a heat insulator 8, respectively. The metal part 10 is formed so that the area of the plate is larger than the contact area with the end part of the element 5. In this way, the areas of the case 1 and the heat insulator 8 on which pressure acts from the element 5 can be made remarkably large. Therefore, contact between the members can be securely maintained in assembling. A time wherein first preliminary pressure is applied is strikingly shortened. Furthermore, deterioration in lineary characteristic in sensitivity due to the deformation of each member can be prevented.

IPC: H04N5/08
Filed: 1989-06-27
Abstract: PURPOSE:To reduce the circuit current and to prevent the deterioration in the frequency characteristic when a PNP transistor(TR) is employed by using a load TR as a grounded-base form. CONSTITUTION:An emitter of a 3rd PNP TR Q3 whose base connects to a constant voltage source 5 to form a grounded-base form connects to a collector of a 1st TR Q1. The 3rd TR Q3 is a load of a differential amplifier 4. That is, since the frequency characteristic of a grounded-base PNP TR is not deteriorated in general, it is not required to use lots of current flowing in a synchronization expansion circuit of the constitution of employing the PNP TR as its load to improve the frequency characteristic. Even when an input signal level rises, the circuit current is not increased limitless while the constant current of a constant current source is taken as upper limit. Thus, the circuit current is reduced without losing the frequency characteristic.

Filed: 1993-07-02
Abstract: PURPOSE:To suppress higher harmonics in a power supply by feeding high frequency current directly from the power supply to a load circuit through a switching means and removing the high frequency components through a capacitor connected in parallel with a rectifier circuit. CONSTITUTION:Pulsating current is fed from a rectifier circuit 2 through a coil 14 and an isolation diode 15 to a capacitor (CS) 3 which is thereby charged. When a transistor(Tr) 5 is turned ON by a drive signal delivered from a control circuit 8, the CS 3 is discharged to a load circuit 13 thus charging a CS 12. When a Tr 16 is turned ON in synchronism with a Tr 5, current flows from the rectifier circuit 2 through the coil 14, the Tr 16, a diode 17, a discharge lamp 10, the Cs 12 and the Tr 5. The current is combined with the current flowing from the CS 3 through a coil 9 and charges the CS 12. In other words, high frequency current flows depending on the voltage of the commercial power supply 1 and the high frequency component is eliminated by a capacitor 18.

IPC: B65H31/06
Filed: 1983-09-07
Abstract: PURPOSE:To exactly send paper into a vertical stacker, by providing claws on paper discharge rollers so that the paper discharged into the stacker by the rotation of the rollers is further pushed into the stacker by the claws. CONSTITUTION:When paper discharge rollers 15, 16 with claws 27 are rotating, the rear edge of paper 22 is surely engaged with the claws so that the paper is sent out while being certainly pushed up in the direction of paper discharge. When the rear edge of the paper 22 has reached such a rotation angle position as to disengage from the claws 27 by the weight of the paper 22, as a result of the further rotation of the rollers 15, 16, the paper drops along a paper housing surface in a stacker 12. Subsequently, the rotation of the claw 27 in the same direction as that of the paper discharge roller 16 acts so that the paper 22 is pushed into the stacker 12 while the paper is driven down to the bottom 12a of the stacker. Sheets of paper are thus sequentially trued up and housed in the stacker 12.
