Patent JP-H06314046-A (JP)
Title: Fixing device
Inventor: NISHIDA HAJIME
IPC: G03G15/20
Filed: 1993-04-30
Abstract: PURPOSE:To shorten rising time for the surface of a fixing roller to reach the specified temperature by arranging a high power heater and a low power heater inside the fixing roller. CONSTITUTION:The low power heater 10a and the high power heater 10b are arranged inside the fixing roller 12, which are controlled for turning-on at need. Namely, there is either case that the low power heater 10a is turned on or the case that the high power heater 10b is turned on. At first, a facsimile mode is judged whether it is in a copying mode, and when in the facsimile receiving mode which is mostly for reception in the unattended state, the low power heater 10a is turned on, because the rising time is not a matter of concern. Then, at the time of the copying mode which is mostly for the attended state, the high power heater 10b is turned on, thus, the standby time for the operation of the first copy can be shortened.

Abstract: PURPOSE:To control a speed in rushing and to prevent the breakage by using a rotating type electromagnetic drive means capable of controlling the speed in rushing, gradually raising the drive voltage, and slightly lowering it after loading to smooth an operation of a magnetic head. CONSTITUTION:A disk 14 connected coaxially directly to a rotating shaft 22 of a rotating type electromagnetic drive means 13 attached to a supporting member 8 is rotated by driving the rotating type electromagnetic drive means 13, and then a pin 21 protruding on the disk 14 engages with a groove of an end of a connecting member 17, so that said end part of the connecting member 17 rotates centering a supporting shaft 19. Accordingly, the other end of the connecting member 17 vertically moves, and the other end engages with an arm 3 of a magnetic head assembly 1 and by the vertical movement, the loading and unloading of a magnetic head 2 is carried out. In a groove 20 for a stopper disposed on the disk 14, a pin 15 for the stopper studded on an enclosing case of the rotating type electromagnetic drive means 13 is interposed and the positioning of the respective positions of the disk 14 on loading and unloading of the magnetic head is performed.

Title: Photoconductive member
Inventor: MATSUO TAKESHI
IPC: G03G5/147
Filed: 1984-05-25
Abstract: PURPOSE:To improve durability of a surface protecting layer by forming a surface protecting layer of amorphous carbon or of a hard carbon. CONSTITUTION:The amorphous carbon or hard carbon constituting the surface protecting layer is the carbon in a structure wherein the so-called graphite crystal is not grown yet. For example, the carbon is one having diamond type structure, pyrolytically generated pyrolytic carbon, or one called generally i-carbon. The suitable thickness of the layer may be 0.05-5mum, if it is too thin, the function as a surface protecting layer is deteriorated. On the other hand, if it is too thick, the activity thereof as a photosensitive body may be influenced adversely. Thus, the mechanical strength of the surface protecting layer, particularly the hardness is improved, thus, the abrasion resistance and the durability are remarkably improved, and the number of paper sheet suitable for continuous printing, which has hitherto been considered as an important problem, is increased remarkably.

Title: Device for automatic preparation of silver halide photographic emulsion
Inventor: YAMADA MOTOSHIGE
IPC: G03C1/015
Filed: 1990-04-20
Abstract: PURPOSE:To prepare a silver halide emulsion with good accuracy by providing a dispenser with a capability to sense a liquid level and averting the more than needed submergence of a suction nozzle tip into a liquid. CONSTITUTION:The dispenser 10 which can add additive chemicals into a silver halide emulsion container is provided with the capability to sense the liquid level. The liquid level is sensed by a method of utilizing the slight change in the pressure when the air sent by a compressor 18 is blown from the tip of the nozzle 11 and when the nozzle sinks into the liquid. This change is detected by a high-sensitivity type pressure switch 17 and the descending of a nozzle mounting part 10a is stopped. The capability to sense the liquid level, therefore, acts to prevent the nozzle tip from submerging more than needed into the additive chemicals when the nozzle mounting part 10a of the dispenser sucks the additive chemicals. The staining of the nozzle tip is thereby lessened and the dripping of the liquid sticking thereto is prevented. The unnecessary intrusion of the chemicals into the emulsion container is prevented in this way and the silver halide emulsion is prepd. with the good accuracy.

Abstract: PURPOSE:To enable to monitor undesirable current at read-in and to increase the detection sensitivity, by detecting the current having a given relation with the write current fed to the read and write head via the transistor. CONSTITUTION:At with the write state in low level of the terminal 1, the transistor Q5 is non-conductive and the transistors Q4 and Q8 are conductive, and the current I5 flows in the transistor Q2 the base current of which is restricted via the transistor Q1, and a constant current I4 flows via the resistor R2, by the current I2 flowing out from the transistor Q2 and the writein current I6 of the read write head 5 flowing to the transistor Q4. Those currents have a relation of I2=I4-I6=I5 at all times via the transistors having relations each other, and the write-in current can be detected with high sensitivity with the detection current of the flowing in end B of the transistor Q2 inversely in proportional to the write-in current I6. Further, at read-in state, if the transistor Q4 is not in OFF state due to failures, since unnecessary write-in current is detected at read-in, the monitor of failure can be achieved.

Title: Magnetic circuit
IPC: H02K41/02
Filed: 1992-03-31
Abstract: PURPOSE:To avoid the corrosion of a permanent magnet by a method wherein the circumference of a coated permanent magnet and a yoke is further coated with a coating film (CS). CONSTITUTION:A first layer coating film (CS) 6 is applied to the circumference of a permanent magnet 3. The permanent magnet coated with the CS 6 is bonded to a yoke 2 with a bonding layer 7. A second layer CS 8 is applied to the circumference of the permanent magnet 3 coated with the CS 6 and the yoke 2. The CS and the CS 8 may be made of the same material or different materials. If different materials are employed, the CS 6 is made of material which has a high bonding strength to both the permanent magnet 3 and the yoke 2 and then the CS 8 is made of material which can be elastically deformed, i.e., resin. As the CS 8 absorbs strain produced in the bonding layer 7, crackings produced in a coating part A between the lower corner part of the permanent magnet 3 and the yoke 2 can be avoided, so that the permanent magnet 3 can be protected from corrosion.

Title: Air conditioning apparatus
Inventor: KURIBARA SUSUMU
IPC: F25B49/02
Filed: 1992-03-31
Abstract: PURPOSE:To enable a refrigerant sensor to correctly decide whether the filling amount of refrigerant is optimum or insufficient in spite of the number of rota tion of a compressor. CONSTITUTION:In a step 1, the number of rotation N of a compressor in a cooling cycle is detected and in a step 3, a deciding value IN, corresponding to the number of rotation N, is read from a characteristics map and in a step 4, an electric current I is read from the thermistor of a refrigerant sensor. Next, the electric current I is decided in a step 5 whether the electric current I is bigger than the deciding value IN or not in a step 5 and when it is 'NO', the filling amount is optimum but when the decision is 'YES', the thermistor is not cooled by liquid-phase refrigerant and, therefore, it is informed by an informing device that the refrigerant is short in a step 6. According to this method, the correct filling amount of refrigerant can be decided regardless of the number of rotation of the compressor.
