Title: Stress imparting type polarized wave maintaining optical fiber
Inventor: HOSAKA TOSHITO
IPC: C03C13/04
Filed: 1986-05-26
Abstract: PURPOSE:To maintain polarized wave by making use of the stress induced double refractions occurring in the difference in the coefft. of thermal expansion from an intermediate layer material by using a material essentially consisting of GeO2 glass for a core and clad. CONSTITUTION:The core 1 is, for example, pure GeO2, the clad 2 is the GeO2 added with, for example, 2mol% fluorine, and the intermediate layer 3 is the GeO2 glass added for example, with about 20mol% P2O5. A low loss is thereby obtd. and the polarized wave maintaining capacity is improved in the region of 2-3mum wavelength where a quartz optical fiber cannot be used. Since the nonlinear efficiency is high, this fiber is applicable to Raman amplification and soliton transmission, etc.

Filed: 1988-05-17
Abstract: PURPOSE:To achieve a detection of a temperature change within a space area, by sealing up a hydrogen occluded matter airtight into a hollow cylinder tube comprising material with a better heat conductivity together with a hydrogen gas. CONSTITUTION:A hollow cylinder tube 1 of a temperature sensor disposed within a space area is made of material with a better heat conductivity and hydrogen is reversibly occluded into the tube 1 with a change in temperature to seal up a dischargeable hydrogen occluded matter 5 airtight together with a hydrogen gas. Then, a pressure sensor 2 is provided at one end of the tube 1 to detect changes in pressure within the tube 1. Therefore, when a temperature change is caused at any part within the tube 1, a hydrogen occlusion/discharge reaction occurs in the matter 5 within the tube 1 to cause a change in the pressure. Checking this pressure change with the sensor 2 enables detection of a change in the temperature within the space area.

Title: Control method for toner fixing device
Inventor: WATARAI SHINICHI
IPC: G03G15/20
Filed: 1988-05-17
Abstract: PURPOSE:To improve toner fixing performance at the low-temperature start of a printer while suppressing the supply amount of electric power to a heat roller and damage due to process initialization by performing rotation control over the heat roller and a pressure roller unless set temperature is reached within a specific period. CONSTITUTION:In normal temperature environment or when operation is restarted after a temporary stop, the temperature of the heat roller 10 and pressure roller 12 reach set temperature during rotary driving or in a specific period after the rotation stop to suppress initial stress due to unnecessary roller rotation. When both rollers 10 and 12 do not reach the set temperature, on the other hand, it is considered that the printer 20 which is left in a low ambient temperature state is powered on, and those rollers 10 and 12 are brought under the rotation control a specific period later. Consequently, while the supply amount of electric power to the heat roller 10 and the damage due to process initialization are suppressed, a state wherein toner can securely be fixed even in low-temperature environment is entered in a short time and the commodity properties of the printer is improved.

Abstract: PURPOSE:To shorten energizing time and to reduce power consumption by providing a latch mechanism which holds mechanically a loading state and a latch release means which actuates the latch mechanism at the beginning of generation of the unloading signal to a head and releases a latch state. CONSTITUTION:When a head loading signal (a) is produced in a head unloading state, a front end differential signal (b) is produced at the rise of the signal (a) and a head loading solenoid 12 is energized. Then a plunger 13 is over-driven and attracted and a head loading arm 9 is turned counterclockwise. Thus a head is loaded and a latch pin 21 is locked at a position P1 of a heart-shaped cam 18. When the signal (b) is not available yet, the plunger 13 is reset by a spring 16 and locked at a position P2. Hereafter the head is kept in a loading state. When a rear end differential signal (c) is not available yet, the plunger 13 is reset and the arm 9 is turned clockwise. Then the head is unloaded. Therefore, no energization is needed in the periods excepting for each minute time and the energizing time is greatly reduced together with reduction of power consumption.

Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To provide a direct type focal plane shutter capable of setting attracting force with an electromagnet, in consideration of only the force of a driving spring. SOLUTION: This figure shows a state where a setting means 10 is slightly turned counterclockwise to return to an initial position, prior to an exposure operation, after releasing is attained. When the setting member 10 is further turned, a pushing part 10b is separated from the part to be pushed 4d of a preceding sector driving member 4 and the driving member 4 is slightly turned by the force of a press spring 8 and the driving spring 9. Then, an attaching part 4c is abutted to an end part 7b1 provided on an iron piece shaft 7b of an iron piece member 7. However, the attracting state by the electromagnet 12 is maintained with respect to impact force by the abutting, because the pressing part 13b of a pressing member 13 restrained by a hook member 15 presses the end part 7b1 .  A cam part 10g rotates the hook member 15 clockwise by the rotation of the setting member 10 after that, to retreat the pressing part 13b out of the locus of the actuation of the iron piece member 7.
