Title: Vacuum valve circuit breaker
Inventor: OKAWA MIKIO
IPC: H01H33/66
Filed: 1989-02-09
Abstract: PURPOSE:To make it unnecessary to open the lid of a case container each time to check a vacuum failure inside a vacuum valve housed in the case container in a current which flows through the earthing conductor in the container. CONSTITUTION:An electrostatic board 11 which approaches to the external circumference of a vacuum valve 2 opposed to an arc shielding 16 and electrostatically joints to the arc shielding 16 and also electrically connects with a case container 1 is installed. The potential of the arc shielding 16 in the vacuum valve 2, therefore, becomes an intermediate one between the potential of an earthing conductor and a ground potential, and when a vacuum failure occurs in the vacuum valve 2, a discharge occurs at a contact 14 or between the axis and the arc shielding 16; however, as there is an insulation cylinder 15, a current simply flows through an electrostatic capacity. Then, whether there is an electric component specific in a partial discharge caused by failure in that electric current is detected. Thereby, a vacuum failure inside a vacuum valve 2 can be detected without opening the lid of the case container.

Title: Method of coupling liquid flow pipes and retainer plate of heat exchanger
Inventor: NABEYA MASATOSHI
IPC: F28F9/14
Filed: 1982-02-26
Abstract: PURPOSE:To prevent the trouble of water leakage at the coupling portion of liquid flow  pipes and a retainer plate without damaging the inner surface of a rubber packing, by coupling the liquid pipes and the retainer plate by use of a cap member having a thin cylindrical portion under a conical head portion. CONSTITUTION:In coupling end portions of many round pipes constituting the core of a heat exchanger to a retainer plate constituting one surface of the tank wall in the manner that the pipes are extended through the retainer plate in a liquid-tight manner, the liquid pipe 5 is inserted into the main body 6a of a rubber packing 6 after fitting a cap member 7 to one end of the liquid pipe 5. Therefore, the end portion of the pipe 5 fitted with the cap member 7 is extended through the main body 6a while compressing the rubber packing 6 elastically. In press fitting the liquid pipe 5, the cap member 7 does not damage the inner peripheral surface of the main body 6a of the packing 6, and at the same time, the fitting operation can be carried out with ease. Finally, the operation is completed by drawing out a cylindrical portion 7b of the cap member 7 from the space between the main body 6a of the packing 6 and the liquid pipe 5 so that the rubber packing 6 is elastically compressed between an erected wall 4 and the pipe 5.

Title: Optical multiplexer and demultiplexer
Inventor: FUJII YOJI
IPC: G02B27/28
Filed: 1986-02-14
Abstract: PURPOSE:To nearly equalize the S wave component and P wave component of incident light from a semiconductor laser to an interference filter to each other and to produce a nonpolarization state by setting the power ratio of the S wave component and P wave component of radiation linear polarized light to the incidence surface of the interference filter within a range of 0.7-1.4. CONSTITUTION:Light with wavelength lambda1 which is emitted by the semiconductor laser 5 becomes parallel luminous flux by passing through a lens 2-1 and is incident on the interference filter 3. The semiconductor laser 5 is so set that its active layer 7 crosses a y-z plane at 45 deg., and the polarization direction of the radiation linear polarized light from the semiconductor laser 5 is made to cross the incidence surface of the interference filter 3 at 45 deg.; and thus the S wave component and P wave component are nearly equalized to obtain the nonpolarization state equivalently. This corresponds to a 0.7-1.4 power ratio of the S and P wave components. Thus, the interference filter 3 has the same characteristics even if polarized and unpolarized light beams are both incident on the interference filter 3.

IPC: H02M3/335
Filed: 1980-03-10
Abstract: PURPOSE:To obtain a multioutput switching regulator SR having a high efficiency and high stability of each output with a compact and light-weight structure, by winding the choke coil of each rectifying circuit of the SR round a common iron core. CONSTITUTION:The AC voltage generated at the switching elements 2 and 2' is supplied to the primary winding of a transformer 3; and the output voltage of the secondary windings 14A-14C of the transformer is rectified by a rectifying circuit and then supplied to the loads 9A and 9C after a smoothing. In this case, the smoothing choke coil 11 is wound around a common iron core, and the output voltage EA and EB are connected magnetically to a circuit having the output voltage EC within the coil 11. Thus the voltage Ea and Eb become constant regardless of a continuous or discontinuous state of the choke current as long as the voltage EC is constant. Accordingly a connection of a dummy load is not required, and thus a compact and light-weight choke coil can be obtained efficiently owing to a winding around a common iron core.

Title: Electrophotographic apparatus
Inventor: NISHIKAWA MASAHARU
IPC: G03G15/30
Filed: 1979-03-12
Abstract: PURPOSE: To prevent the occurrence of undesirable stainings of recording paper by gently decreasing the charged charge amount of electrostatic latent images toward the outer side.  
     CONSTITUTION: A photoconductive layer 42 at a width slightly narrower than the maximum recording paper width allowed excluding the step part is deposited on the conductive drum 41 formed with a step part in the portion where a stripping claw 26 acts to form a photosensitive drum 16. A shield body 43 is provided between a corona charger 18 and photosensitive drum 16. As a result of this, if the photosensitive drum 16 is charged with a corona charger 18, the distribution of the charged charge amount in the photoconductive layer 42 is zero at the edges and gradually increases in a fixed range from the edges and thereafter becomes constant. Hence, the electric lines of force by the charged charges gradually weaken as they go closer to the end parts of the photoconductive layer 42 so that those portions are hardly developed, thus undesirable linear and belt-form stains do not appear on recording paper.

Title: Method for closely bonding overlay film to injection mold and overlay injection molding apparatus
Inventor: SAKABE ATSUSHI
IPC: B29C45/06
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To closely bond an overlay film to a decorative mold without wrinkling the same when the overlay film to be closely bonded to the decorative mold among the decorative mold and an injection mold is heated and softened to be drawn under vacuum. SOLUTION: After a required amt. of slightly compressed air is supplied in such a state that the peripheral edge part of an overlay film F is fixed to a decorative mold 2A, (2B) by a film clamp 10, the film F is heated and softened to suck the air in the mold. By this constitution, the film F is almost parallelly held without being slackened to be uniformly heated as a whole by a heater 12. When the film F is heated and softened, it overcomes the pressure of internal air to be expanded upwardly to be preliminarily stretched. When the internal air is sucked herein, the overlay film is almost uniformly deformed to become hard to wrinkle. Since the deformation quantity of the film is small by preliminarily stretched quantity, the film F further becomes hard to wrinkle and is cleanly closely bonded to the inner surface of the decorative mold 2A, (2B).
