Title: Molding method of plastic product where thin sheets are juxtaposed
Inventor: MIYAJIMA YUKIO
IPC: B29C33/44
Filed: 1989-03-20
Abstract: PURPOSE:To enable monolithic molding of a plastic product where a large number of thin sheets are juxtaposed at gaps, by a method wherein gap forming molds coming into contact respectively with a surface side and rear side of the thin sheet are pulled out at time intervals. CONSTITUTION:Gap forming molds 3a, 3b coming into contact respectively with a surface side and rear side in a thin sheet 2 are not pulled out at a time, the gap forming mold 3a coming into contact, for example, with the surface side is pulled out and the gap forming mold 3b coming into contact with the rear side is pulled out by delaying a little while. When a cam disc 4 is turned as a concrete device, respective pins 5 provided on a gap forming mold 3a group are moved by being controlled with the same guide grooves 6 respectively, therefore, the gap forming mold 3a group is pulled out at a time. Meanwhile, although the gap forming mold 3b group is pulled out at a time since the respective pins 5 are actuated by being controlled with the same guide grooves 6 respectively in the gap forming mold 3b group also. However, since the guide groove 6 is formed into a concentric circular arc 6' part of the way, the mold 3b group does not move to the part of the way even if the cam disc 4 is turned.

Title: Photographic apparatus
Inventor: HIRANO REIJI
IPC: G03B7/16
Filed: 1978-06-08
Abstract: PURPOSE: To save labor for exposure condition adjustment at the changing of photographing magnifications, make observation and photographing accurate and achieve their efficiency by defining the quantity of light of the lighting source of a light system by the signals by a magnification detecting means and lead-in means.  
     CONSTITUTION: When a focusing lens 3a is focussed at the eye fundus Ef by moving the same and a release is operated after suitably selecting the magnification of a rear lens group 3, then a xenon tube 14 emits light. The emission of this time changes with the time t and is nearly proportional to the current I flowing in the xenon tube 14, thus assuming the waveform as shown in the figure. This emission time is stopped by the time t 0  corresponding to the photographing magnification by the action of a rotary type variable resistor VR for detecting magnifications, whereby the quantity of light to the film is controlled. In addition, the emission intensity of the lamp 11 also changes with the change in the magnification of the lens group 3 and therefore the visual field of always constant brightness may be observed through the finder.

Title: Muting circuit
Inventor: HORIIKE YOSHIO
IPC: H04B1/10
Filed: 1981-05-08
Abstract: PURPOSE:To eliminate noises that is caused during the changeover of switches, by carrying out the switching of the circuit after the application of muting when the circuit is switched by means of a mechanical switch and releasing the muting after the stable working of the circuit. CONSTITUTION:A switch is connected to the side of an FM local oscillating circuit 8 and then switched to a TV local oscillating circuit 9. In a such a case, the oscillation of the circuit 8 is held for a short period of time owing to the electric charge which is charged to a capacitor C1. Thus the oscillation of the circuit 8 is held instantaneously when a band switch S is switched. Meanwhile a transistor Q1 is turned on to apply muting, and as a result, the switch S is connected to the circuit 9. Then the Q1 is turned off after the stable operation to release the muting. As a result, noises caused by switching of bands are absorbed to a muting circuit.

Title: Resonator
Inventor: TANIGUCHI TETSUO
IPC: H03H5/02
Filed: 1988-03-23
Abstract: PURPOSE:To prevent a change in the frequency characteristic and to improve the yield by ensuring the same electrode pattern area on the design even if the pattern print share in upper/lower/left/right directions is caused between the front face and the rear face of a substrate. CONSTITUTION:If the capacitor electrode pattern 2b is deviated by a size l4 in a direction of arrow P1, the opposed area with the capacitor electrode pattern 3b is increased by a part shown in hatched lines 20, while the opposed area with the capacitor electrode pattern 3b is reduced by a part shown in hatched lines 21. However, the area of the increased part (hatched lines 20a-20c) of the opposed area between the electrode patterns 2b and 3b and the area of the decreased part (hatched lines 21a, 21b) are identical. Thus, even if the capacitor electrode pattern 2b is deviated in a direction of arrow P1, there is no increase/decrease in the opposed area of the capacitor electrode patterns 2b, 3b and then the capacitance of the capacitor is unchanged. Then the capacitance of the capacitor is always kept constant to prevent the fluctuation in the resonance frequency.

Abstract: PURPOSE:To approach and leave to/from a sheet processing device at an image forming device without damaging the accurate positioning of a sheet carrying path, by supporting and coupling the sheet processing device at the image forming device without sticking it on a floor. CONSTITUTION:Since a sorter coupling mechanism consists of upper and lower part links 20 and 22 at an inner side, upper and lower part links 20' and 22' at this side, and a torsion spring 30, etc., an angular moment due to the weight of a sorter is scarcely generated at each link, therefore, the engaging piece of a lock lever 27 which supports the sorter, when a sorter S is coupled with a copying machine M main body. When a jamming is generated in an ejecting sheet, the hooking part 25a of the lock lever comes off the engaging piece 27, and furthermore, it is pressed in the arrow head A direction, and is left from the copying machine M main body, and as each link supporting the sorter is moved and displaced smoothly in the a direction to leave from the copying machine M main body, descending and leaving is performed at an appropriate speed by the buffering function of the torsion spring 30 having various dimensions corresponding to the weight of the sorter. At such a time, it is enough to touch the sorter softly for the operator.

Abstract: PURPOSE:To make a circuit board small-sized by a method wherein a plurality of independent relay ranges are formed, via an insulating layer, on one face of a relay member between the member and a capacitor structure part and one part out of the relay ranges is connected electrically to an electrode part. CONSTITUTION:At a relay member 3a, electrodes 13, 15 are formed on the surface and the rear surface by sitting a dielectric 14 as the center; a capacitor structure is formed. An insulating layer 12 is formed on the surface of the surface electrode 13; a plurality of conductive and independent relay ranges 4 are formed on the surface of the insulating layer 12. In addition, a relay range 4a in one part of the relay ranges is connected electrically to the electrode 13. At the relay member 3a, a semiconductor chip 1 and a terminal 7 are connected by metal wires 6, 6'. As a result, a difference in level at each connecting face is limited; the thickness of the relay member 3a is limited to 0.4 to 0.8mm. Consequently, a capacitor structure part of the relay member 3a is formed. A material whose permittivity is high is selected as the dielectric 14, and the thickness of individual layers is formed to be thin as far as possible.

Filed: 1987-03-26
Abstract: PURPOSE:To prevent the occurrence of sympathetic sounds to a general telephone by disconnecting general telephones, which are connected in parallel, at the time of sending a dial signal from an automatic reporting device and at the time of opening a general subscriber's line. CONSTITUTION:If a sensor senses an abnormal state, a signal is sent from a sensor interface part 15 to a control part 14 and a data sending circuit 13 sets sending data, and simultaneously, the control part 14 turns on a D2 relay 4 to close a dial shunt contact 3. Since the control part 14 turns on a diode 21 out of diodes 21 and 22 to open a K relay 17 and opens a contact 16 for disconnection from general telephones at this time, general telephones and the reporting device are disconnected from each other. Though the dial signal is sent thereafter, general telephones are not affected by resonance or the like at all. After the dial signal is sent, the D2 relay 4 is turned off but a Di relay 2 is kept turned on and is turned off after data sending. Since a transistor 18 is turned off after a delay time by the time constant of a resistance 19 and a capacitor 20 to connect the contact 16, general telephones are not affected by resonance or the like even at the time of opening the general subscriber's line.
