Title: Color image forming device
Inventor: TERADA HIROSHI
IPC: G03G15/16
Filed: 1990-04-18
Abstract: PURPOSE:To reduce the size of the device by enabling a transfer means to be separated from a photosensitive body and varying the speed of transfer conveyance. CONSTITUTION:A transfer conveyance part 60 has two states, i.e. a state wherein part of a belt 63 suspended by rollers 61 and 62 and movable rollers 67 and 68 is pressed lightly against the photosensitive body 11 and a state wherein the belt separates from the photosensitive body 11, and the conveyance part moves as shown by an arrow B. When the belt 63 is pressed against the photosensitive body 11, the belt moves at the same speed with the outer peripheral speed of the photosensitive body 11, but when the belt separates, the belt moves irrelevantly to the speed of the photosensitive body 11, e.g. at the moving speed of recording paper 56 that a fixation part 70 requires. Consequently, when image transfer to recording paper ends, the transfer conveyance part is separated from the photosensitive body immediately and the recording paper is sent in a fixing means 70 at the speed irrelevant to the speed of the photosnesitive body; and fixation conditions can properly be changed according to the kind of form and the purpose, and the device is reducible in size.

The outputs from the sensors are sampled at high speed, and a point changing from lead presence to lead absence is detected and the rear end of the lead is decided. The time of the opening of the shutter 72 or the time immediately after the start of lead-feed operation is used as the start period of the sampling at high speed. The detecting sensors 94, 96 are positioned just under the shutter 72, thus detecting the rear end of the lead before the lead is introduced completely into a holder, then quickly closing the shutter 72 immediately after the completion of lead falling, provided that multiple falling can be prevented.

When a light 5 is projected from a light projecting element 3 onto the surface of the cooler 1, the light is reflected almost in the same direction by the film 7 and reaches a light receiving element 4. The state of a frost or dew condensation is detected by the change of this light receiving amount. As the element 3 and the element 4 may be provided very closely, the whole device is much compacted.

Abstract: PURPOSE:To make the dehydration treatment surer and a device simpler by providing spiral feed venes of a hollow shaft having the diameter increasing gradually from the rear part toward the front part and rotating the shaft in a casing. CONSTITUTION:The hollow shaft 30 for compressing a material which is to be treated and is supplied through a supply port 21 while feeding said material to a discharge port 22 side is rotatably provided in a casing 20. The shaft 30 is made gradually larger in diameter from the rear part toward the front part and is perforated with many holes 32, 23. The material to be treated is fed by the feed vanes 31 toward the port 22 side when the shaft 30 driven by a motor is rotated at a low speed. The water in the material is removed by the gradually decreasing gap between the shaft 30 and the inside circumferential surface of the casing 20 and is leached to the outside through the holes 32, 23. Since the shaft 30 rotates at a low speed, the device is made smaller and simpler and the sure dehydration is executed.

Title: Solid thermal accumulator device
Inventor: MOCHIZUKI MASATAKA
IPC: F28D15/02

Abstract: PURPOSE:To reduce a thermal transmitting resistance during either a thermal accumulation or a thermal radiation and obtain a superior thermal responding characteristic by a method wherein gas of a high thermal conductivity is pressurized and enclosed between an outer surface of a pipe passage for thermal transferring medium and the thermal accumulation material. CONSTITUTION:As an electric heater 9 is energized and heated to heat and increase a temperature of a thermal accumulation material 2, the thermal accumulation material 2 may store heat as a sensitive heat. Since working liquid is heated by heat of the thermal accumulation material 2, the liquid may evaporate and its vapor is fed out from a steam pipe 6 through an upper header pipe 3. A thermal transfer in this case is carried out through a pipe forming an evaporator 1 and a spacing 8. However, thermal high conducting gas such as helium gas is pressurized and enclosed in the spacing 8, so that a thermal transfer against the evaporator 1 from the thermal accumulation material 2 is carried out well and in addition the evaporator 1 and its inner working fluid are directly contacted to each other. So, a better thermal transfer between both of them can be performed. Thus, at the thermal accumulation device, a less thermal transfer resistance with respect to the working fluid from the thermal accumulation material 2 can be attained, an efficient heating of the working fluid to obtain its increased temperature and then a better thermal responding characteristic can be provided.

Abstract: PURPOSE:To make checking easy with a simple constitution by providing a light emission display circuit which is driven in the charging process of the capacitor of a light emission stop circuit in parallel with said capacitor. CONSTITUTION:The series circuit of a neon tube 12 and capacitor 13 and a thyristor 11 are connected to the capacitor 15 of a light emission stop circuit and the primary side of a transformer 16. When automatic dimming operation is accomplished and a bypass pipe 17 starts discharging upon conducting of a thyristor 11 and discharging of the capacitor 15, the capacitor 13 also discharges through a diode 14 and thyristor 11. Thereafter, the capacitor 15 is charged through the diode 8 and resistance 9, but when the discharge voltage reaches the charging start voltage of the neon tube 12, this is lighted and when the charge voltage of the capacitor 15 lowers and becomes lower than the discharge sustaining voltage of the neon tube 12, this is put out and the capacitor 15 is again charged. Since the neon tube 12 flickers through repetition of this, the state of dimming operation may be readily checked.
