Title: Optical attenuator
Inventor: FUJITO KATSUYUKI
IPC: G02B5/00
Filed: 1986-05-20
Abstract: PURPOSE:To obtain an optical attenuator for exerting no influence at all on an analog transmission characteristic, and also, to simplify a manufacture procedure, a process and an assembly, by constituting the optical attenuator so that a reflected light or a multiple reflected light is not transmitted in a fiber. CONSTITUTION:An emitted light from a fiber 1 becomes parallel rays by a lens 2. H1 is a main plane of the first lens 2, placed so that an optical axis of the first lens 2 and the center of the fiber emitted light cross each other (point B) on the main plane H1, and a light beam which has passed through the first lens 2 is focused by the second lens 3, and led to a core part of the second fiber 4. A position relation of this second lens 3 and the second fiber 4 is all the same as a position relation of the first fiber 1 and the first lens 2. That is, on the contrary, when a light beam has been emitted from the second fiber 4, this light becomes parallel by the second lens 3, and also, the center of the light crosses an optical axis O2 of the second lens at a point C on a main plane H2. A tilt angle theta1 of the end face of the fiber is selected so that a Fresnel reflected light component generated by this end face is not transmitted in the reverse direction.

Title: Arc current detecting device
Inventor: SHIMADA MOTOHIKO
IPC: G01R31/00
Filed: 1984-06-04
Abstract: PURPOSE:To detect the generation of an arc without expecting the extinction of an arc current by detecting arc current on conditions that the current value is above the prescribed value and yet of irregular variation. CONSTITUTION:A differentiation circuit 6 passes through the portion of current variation. In the accident excluding an arc of the short in power system, etc., however, the current value is hardly changed and it is not passed through. The arc current in a power system and a troubled current are therefore discriminated by whether or not they can pass through the circuit 6. The size of the output of the circuit 6 is compared with the reference voltage by a level discriminating circuit 7 and in case of the output of the circuit 6 being larger a point (d) becomes a high level. When the high levelled condition is continued for the prescribed time, then, the point (d) becomes a low level and a relay contact 11 is turned on with the excitation of a relay coil 9. An over-current detecting circuit 5 is motioned similarly and turns a relay contact 10 on when the over-current holds the current value beyond the prescribed for the prescribed time. At the time when the prescribed time proceeded after the generation of an arc, relay contacts 10, 11 are turned on and an arc generation output signal is outputted, and the detection of the arc generation is enabled without expecting the extinction of an arc current.

Title: Picture density control method
Inventor: MOCHIZUKI MANABU
IPC: G03G15/11
Filed: 1979-09-08
Abstract: PURPOSE: To increase the precision of picture density control by changing the targeted transmissivity of a developer in electrophotography according to a carrier liquid resistance value, when keeping picture density constant by keeping the transmissivity of the developer constant.  
     CONSTITUTION: In order to prevent the picture density from lowering as a developer is consumed, the transmissivity of the developer is measured by light source 3 and photoelectric element 4 and fixed to a target value to keep the picture density constant. However, since the continuation of development results in that the mixture of impurities, etc., causes a decrease in electric resistance of a carrier liquid, an electrostatic latent image on a photoreceptor lessens due to discharge through the carrier liquid more than the sticking of a developing toner, reducing the picture density. For this purpose, the resistnce of the carrier liquid is measured by electrode couple 1 and in inverse proportion to the resistance, the targeted transmissivity is increased, thereby keeping the picture density even when the carrier liquid varies in resistance.

Title: Method of measuring temperature in furnace
Inventor: ARAI OSAMU
IPC: G01J5/00
Filed: 1978-09-20
Abstract: PURPOSE:To simplify the calibration of a temperature signal of a furnace and raise the accuracy of inspection, by detecting the contamination of a window glass through a reference heater and calibrating the temperature signal depending on the result of the detection at the time of measurement of the temperature of the furnace. CONSTITUTION:When the temperature signal is calibrated, the measurement is suspended and a gate valve 8 is closed. The reference heater 11, whose temperature is cotrolled to be uniformly distributed by a temperature regulator 21, is inserted into a calibration chamber 9. The surface temperature distribution of the reference heater 11 is measured by a temperature detector 7 to produce a signal. The signal is applied together with the temperature signal of the reference heater 11 to a calibration unit 22 so that these signals are compared with each other and the degree of contamination of the window glass 5 is calculated and stored. When the temperature in the furnace is measured, a furnace temperature signal applied to a temperature detector 7 is calibrated on the basis of the stored information.

Abstract: PURPOSE:To change dies without using a moving bolster. CONSTITUTION:A used die 4 is held by a die holder 8 provided in a slide 3, and the die 4 is raised by the slide 3. In this state, a carrier truck 10 mounted with a die 4' to be used next time is carried into a press body 1, and after the used die 4 is mounted on this carrier truck 10, the truck 10 is moved so that the die 4' to be used next time may be in a lower part of the slide 3. Then, after the die 4' to be used next time is held by the die holder 8 and raised by the slide 3, the carrier truck 10 mounted with the used die 4 is carried out from inside the press body. Thereafter, the slide 3 is lowered to fix a lower die 4b to a bed 1a and an upper die 4a to the lower face of the slide 3. Thus, since the die 4 can be changed by using the carrier truck 10, a moving bolster large in size and heavy in weight is unnecessitated, thereby the overall height of the press body is made low.
