Title: Soldering device
Inventor: KISHIDA RIYOUJI
IPC: B23K1/00
Filed: 1983-08-09
Abstract: PURPOSE:To provide a titled device which forms heat transmitting rib parts without distortion of a pipe material by moving a tapered mandrel to press the heel blocks in the bore of the pipe material thereto, pressing the projecting members each having a brazing material on the contact part to the outside circumfference of the pipe material by means of inductors and brazing the members by the high frequencies generated by the coils built in the inductors. CONSTITUTION:Split heel blocks 4 are put into the bore of a pipe material 1 and a tapered mandrel 3 is moved to press said blocks to the bore surface. Rib members 2 each having a brazing material on the contact surface are put into the recesses of split type inductors 10, 11, 12, 13 and are fitted to the outside circumferential surface of the material 1. The members 2 are pressed to the outside circumferential surface of the material 1 by means of a fastening ring 20. Electricity is conducted to the water- cooled high-frequency coils 15-18 in the inductors 10-13 to heat the members 2 and to braze the same to the outside circumferential surface of the material 1. The heat transmitting rib parts 2 of the material 1 are formed by such procedure. The pressing of the blocks 4 and the inductors 10-13 are balanced and there are practically no internal and external distortions of the material 1 owing to the formation of the rib parts 2. The material 1 is thus made into the good heat transmitting pipe.

Title: Driving system for liquid crystal shutter
Inventor: MORI KOICHI
IPC: B41J2/44
Filed: 1986-06-23
Abstract: PURPOSE:To obtain a sufficient light quantity, and also, to improve the contrast by using a polarizing plate of a parallel nicol as two polarizing plates for inserting and holding a liquid crystal plate, and applying an off signal to a group previous by one to a group of each microshutter, in the latter half of a period of a selection timing of said group. CONSTITUTION:A polarizing plate of a parallel nicol is used as both two polarizing plates for constituting a liquid crystal shutter, therefore, both faces of a liquid crystal 16 is inserted and held by polarizing plates 21, 22 of the parallel nicol. When a signal fH of a higher frequency than a cut-off frequency fC is applied to segment electrodes SG1, SG2,..., and a signal -fH whose phase is opposite to said signal fH is impressed to common electrodes CM1, CM2, a liquid crystal molecule becomes an initial orientation state that it is parallel to glass substrates 14, 15, and also, has been twisted by 90 deg. between the polarizing plates 21 and 22, that is, an electric field is not impressed to the liquid crystal 16. Therefore, a light beam from a light source 11, whose optical axes have been put in order by the polarizing plate 21 of the parallel nicol does not transmit through the polarizing plate 22 of the parallel nicol since its optical axis is turned by 90 deg., and the liquid crystal shutter becomes an off-state.

IPC: F24F5/00
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of local corrosion of a heat transfer pipe and to provide an increased life therefor, by a method wherein a surface protection coat is formed at a contact part between a heat transfer pipe made of a metal bent in a zigzagging state at a contact part and a support member. SOLUTION: A heat transfer pipe 1 made of a metal bent in a zigzagging state is supported in a state to span between upper and lower support members 2, and a surface protection coat 4 is formed in the vicinity of a support member 2 between the heat transfer pipes 1, and a contact part 3. Through intervening of the surface protection coat 4, the heat transfer pipe 1 makes direct contact with a support member 2 and formation of a friction mark is prevented. In a way that the surface protection coat 4 forms an oxidation coat formed on the surface of the heat transfer pipe forms an oxidation coat, various problems due to unevenness in formation of an oxidation coat after the starting of use are dissolved and corrosion prevention of the heat transfer pipe is practicable.  Further, by locating a soft member having hardness lower than a surface protection coat between the support member and the heat transfer pipe, peeling of a surface protection coat due to friction with the support member is prevented from occurring.

Title: Cleaner for fixing device
Inventor: SUGA TSUTOMU
IPC: G03G15/20
Filed: 1990-06-04
Abstract: PURPOSE:To maintain the prescribed braking force and to achieve uniform taking-up by pressing the outside diameter of a cleaning web with the almost fixed pressing force at any time regardless of the change in the diameter of each cleaning web in a take-up shaft and an original widing shaft. CONSTITUTION:The cleaning web 12 is moved a little by little in a direction shown by an arrow every time a copying operation is carried out, so that a fresh surface always comes into contact with a heating roller 1. Consequently, the outside diameter of the web 12 wounded around the take-up shaft 14 gradu ally is increased. Simultaneously, the outside diameter of the web 12 wound around the original winding shaft 11 is gradually decreased. During this taking-up operation, web pressing plates 16 and 17 are energized by a torsion coil spring 18, and consequently they are rocked clockwise while centering a supporting shaft 15. By fitting the spring 18 into the supporting shaft 15 and rocking it clockwise, the pressing force is hardly changed. Therefore, from the winding initial condition shown in figure A to the taking-up completion condition shown in figure B, the pressure braking force for the web 12 is not changed and the web 12 can be taken-up always at the fixed pressure.
