Title: Vibration type guide mechanism
Inventor: SAWADA KATSUHIDE
IPC: F16C29/02
Filed: 1988-05-31
Abstract: PURPOSE:To enhance the guide accuracy so as to extremely reduce the frictional resistance in the subject guide mechanism by closely touching mutual sliding contact surfaces being freely slidable and providing a vibration generating means for vibrating in the direction crossing to the sliding contact surface. CONSTITUTION:A moving side sliding contact surface 13 is formed on the lower surface of a moving side member 11 and a fixing side sliding contact surface 14 is formed on the upper surface of a fixing side member 12. On the whole surface of the fixing side sliding contact surface 14, a plate like piezoelectric element is sticked as a vibration generating means. The element 15 is vibrated by a high frequency power source device so as to vibrate the surface of the fixing side sliding contact surface 14, thereby forming a micro gap of several mum between the moving side sliding contact surface and the same. The moving side sliding contact surface 11 is floated slightly over the fixing side sliding contact surface 12 so as to carry out the guide in non-contact state. Thus, it is possible to enhance the guide accuracy and extremely reduce the frictional resistance.

Title: Fuel injection pump and manufacture thereof
Inventor: KUNIMOTO ETSUO
IPC: F02M59/44
Filed: 1983-07-26
Abstract: PURPOSE:To enable an off-quantity oil containing highly hard impurities to be used, by coating a machine-finished surface of a plunger of a jerk type injection pump with a highly hard material such as TiC or the like, and then applying a highly hard material to abutting surfaces of rotating and driving flanges for example by welding, plating or the like. CONSTITUTION:A plunger 3 is coated with a highly hard material such as TiC by chemical vacuum deposition, and after a highly hard material is applied to the two surfaces 321 of a rotating flange 32 that abut against the fork section 61 of a pinion 6 by brazing, welding or plating, the surfaces are coated with the same highly hard coating material. Thus as the plunger surfaces are coated with a highly hard material such as TiC or the like, if there are hard foreign matters in a fuel, the surfaces are hardly damaged. Further as the coating by vacuum deposition can be made very thin, if the accuracy of the stock has been increased, lapping or the like after the vacuum deposition is unrequired, or if lapping is carried out, since its period is short, a plunger having highly hard surfaces can be obtained inexpensively.

Abstract: PURPOSE:To execute a continuous copying at a high speed within a range of rated power consumption by providing a control device for controlling a heating element of an auxiliary heating roller by comparing the detected temperature of the surface of a pressure roller, and a set temperature. CONSTITUTION:By a heating element 4 of a heating roller 1, or a heating element of a pressure roller 2 in addition to said element, both the rollers 1, 2 are heated to a fixable temperature. For instance, in case when copying has been started at the time of t1, a surface temperature of the pressure roller 2 begins to drop suddenly, detected by a temperature sensor 12, and a thermal radiation energy is converted to an electric signal and inputted to each negative side input terminal of two pieces of comparators 13, 14. When the surface temperature of the pressure roller 2 becomes a fixing limit temperature at the time of t2, an output of the other comparator 14 is inverted and a signal is outputted from a timer 19 which has been constituted of a monostable multivibrator, an auxiliary heating roller 9 is made to contact to the pressure roller 2 by operating an auxiliary heating roller driving mechanism 20, and the contact state is held for a prescribed time which has been set to the timer 19. In this way, the power consumption is reduced, and a continuous copying can be executed at a high speed by a rated power consumption.

Abstract: PROBLEM TO BE SOLVED: To prevent the bulging of a thin film at the time of mounting a mask protective member at a mask member. SOLUTION: An air pressure 4 is applied on the thin film 22 when the mask member 3 is brought near to the jig 1 for mounting the mask protective member by directing the pattern surface 31 downward from above in the state of setting the mask protective member 2 on the jig. However, a recessed part 11 is nearly hermetically closed from the thin film 22 and, therefore, the air pressure 5 countering the air pressure 4 acts on the thin film 22 from the base 11 side of the recessed part 11. The thin film 22 is, therefore, substantially prevented from bulging at the time the mask protective member 2 is mounted at the mask member 3.
