Title: Rotary actuator
Inventor: MOMOO KAZUO
IPC: G02B7/00
Filed: 1985-02-20
Abstract: PURPOSE:To obtain a rotary actuator which has the satisfactory frequency characteristics even with the size and the weight approximately equal to a conventional one, by using the ceramics to a holding part for an objective lens which can turn round a rotary center shaft and also can slide in its axial direction. CONSTITUTION:This actuator has the same structure as a conventional one and a material having >=30,000kgf/mm<2> Young's modulus is used to a holding barrel for an objective lens. Here it is required that the specific gravity of said new material is equivalent to that of aluminum. Thus the ceramics of alumina (Al2O3) satisfies those conditions and therefore the objective lens holding barrel uses the ceramics containing >=90% alumina. Furthermore, the side plate part of said lens holding barrel also uses the nonconductive ceramics. This eliminates a phase delay that is produced by an eddy current and secures the satisfactory frequency characteristics.

Filed: 1984-02-24
Abstract: PURPOSE:To prevent a distorted image from being displayed by switching a switch circuit according to the scan mode by means of a discrimination signal from a mode-switching device. CONSTITUTION:When the television scanning mode is selected, the TS switch of a mode-switching device 13 is turned on and a discrimination signal 14 indicating the television scanning mode is delivered to a switch circuit 12. Then the switch circuit 12 opens the gate to send out an electronic image signal from a video amplifier 10 to an external monitoring device. When a mode other than the television scanning mode is selected and the SS1 switch of the mode-switching device 13 is supposed to be turned on, a discrimination signal 14 indicating this is delivered to the switch circuit 12. Then the switch circuit 12 decreases an electronic image signal from the video amplifier 10 to the grounding potential level thereby delivering a black level signal to the external monitoring device. As a result, the CRT picture screen of the external monitoring device becomes dark thereby preventing the distorted image from being displayed.

Title: Disconnection detector of differential signal transmission system
Inventor: KYOIZUMI KOZO
IPC: H04B3/46
Filed: 1994-02-03
Abstract: PURPOSE:To make a disconnection detection easy by detecting the disconnection of a transmission line by the photocoupler connected with the one side of the transmission line. CONSTITUTION:On the side of a transmitter 10, the light emitting diode 16a of a photocoupler 16 is connected with the electrical wire 12a and a diode 17 for bypass is connected in parallel to this light emitting diode 16a. Because external noise intruding in two electrical wires 12a and 12b is cancelled in a receiver 14, the signal C outputted from the receiver 14 becomes the same waveform as an input signal A. Because transmission signals B1 and B2 change between 0 volt and V volt, reverse direction current i1 and i2 flows via a terminating resistor 15. Therefore, one side electric wire is disconnected, the signal flows via the electric wire which is not disconnected and the signal is outputted from the receiver 14. But the current i1 and i2 does not flow, the photocoupler 16 does not operate and the disconnection can be easily detected by a disconnection detection circuit 18.

Title: Device for removing extraneous material in water flow pipe
Inventor: KIKUCHI NOBORU
IPC: F16L55/24
Filed: 1994-02-04
Abstract: PURPOSE:To prevent clogging of a filter member over a long period of time and to prevent captured extraneous materials from being discharged by back flow. CONSTITUTION:The extraneous materials T flowing in a water flow pipe 1 collide against a filter mesh 3 of the filter member 2 and are thereafter made to flow successively downstream until the extraneous materials are captured in a pocket 6 for the extraneous materials. A back flow preventive device 7 is held open to the downstream side during this time and, therefore, the extraneous materials are effectively gathered in this pocket 6 for the extraneous materials. The back flow preventive device 7 held in the open state, thereafter, covers the upstream side of the filter mesh 3 near the pocket 6 even if the water flow direction is reversed and shuts off the conduct of the water into the packet 6, therefore, the back flow of the captured extraneous materials is prevented.

Title: Vertically carrying device for trash
Inventor: KOMORI KENICHI
IPC: B65G11/10
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To control the dropping speed of trash using a simple device. SOLUTION: This vertically carrying device for trash is formed by providing a chute 2 vertically piercing a building 1 for dropping the trash therethrough with an elastically deformable speed reducing skirt 8 projecting inward within the chute 2. Since the trash 3 collides with the speed reducing skirt 8 while dropping, reducing its dropping speed, the dropping speed can be controlled using a simple device. In this vertically carrying device for the trash, a spiral, slant face is formed along the vertical direction of the chute 2, so that the trash drops while sliding on the slant face. Since the trash constantly meets with resistance from the slant face while dropping, the trash is decelerated, so that the dropping speed of the trash can be controlled.

Title: Manufacture of copper coated nb, ti superconductive wire
Inventor: DAIMATSU KAZUYA
IPC: C22F1/18
Filed: 1984-02-22
Abstract: PURPOSE:To lower a wire break-down rate in wire drawing by softening a wire material at a specific temperature and drawing it thereafter while cooling it by a liquid nitrogen. CONSTITUTION:A Nb, Ti alloy rod is fitted to a copper pipe, etc. and many fitted matters are inserted into a copper billet. The billet is radially reduced by hot extrusion to soften the extruded wire rod at a <=500 deg.C. The wire rod is successively drawn while cooling it by a liquid nitrogen. Because of the <=500 deg.C softening, the Nb, Ti filament is prevented from the intrusion of a intermetal compound of Nb, Ti-metallic Cu. Further, because of the low temperature drawing, a nucleus formation due to the intermetal compound formation is restricted, and the formation of intermetal compound of Nb, Ti alloy-metallic Cu is reduced to a small amount. Accordingly, the break down rate in wire drawing is extremely lowered.
