Title: Ignition mechanism of oil burner
Inventor: YAMADA TOSHIHIKO
IPC: F23Q7/08
Filed: 1990-04-26
Abstract: PURPOSE:To ensure ignition operation after the raise of a wig is interrupted by securely engaging a rotatable plate with an engagement part at a wig raise position by forming an engagement hole of a cam plate substantially into a reverse L shape at a predetermined position and pushing the cam plate against a cam spring upon a driver pin fitted to a longitudinal hole part of the reverse L-shaped engagement hole moving upward for returning from an ignition position. CONSTITUTION:A cam plate 15 is supported in the vicinity of an engagement hole 7 of an operating lever 2, and includes its engagement hole 7 formed substantially into a reverse L-shape at a predetermined position, and further a cam spring 16 is provided of retaining the cam plate 15 at a predetermined position. An end part of the cam plate 15 on the side of a longitudinal hole part 7a is located in a locus of a driver pin 8 and also restricts the movement of the driver pin 8. As a first slidable plate 6 is moved upward by a wig vertical movement knob, the driver pin 8 moves cam plate 15 against the cam spring 16 and is as a result located at the end of a lateral hole part. Further, as the first slidable plate 6 is moved upward, the driver pin 8 is fitted to the lateral hole part to rotate the operating lever 2 to an adjustment position of a wig height or to a wig lowering position. Accordingly, wig lifting and driving of an ignition device are simultaneously performed to prevent an ignition heater from being damaged.

Title: Reciprocating internal-combustion engine
Inventor: HAYASHI YOSHIMASA
IPC: F02F3/00
Filed: 1981-07-17
Abstract: PURPOSE:To reduce the noise of slap by installing a vibrator to the other end of an elastic member provided with a connecting rod at one end and by increasing a thrust force directed from the inside of a piston to the wall of a cylinder by the reduction of a tilting angle of the connecting rod. CONSTITUTION:One end of a plate spring-shaped elastic member 4 is fastened to a connecting rod 2 with a bolt 5. A vibrator 6 made of aluminum alloy or steel alloy, is mounted to the other end of the elastic member 4 with a casting bolt. When a clank approaches the top dead center rotating in X direction, the tilting angle of the connecting rod 2 is reduced. With this action, a thrust force F and its reaction force -F increase. While the gas pressure remains constant, therefore, the piston 1 is pressed against a cylinder wall 11 on the thrust side, thereby reducing the noise of slap.

Title: Positioning mechanism of magnetic disk device
Inventor: AIMIYA TAKAYUKI
IPC: G11B21/02
Filed: 1994-05-25
Abstract: PURPOSE:To improve the positioning accuracy of a positioning mechanism of magnetic disk device and to reduce the production cost.

Title: Relief valve
Inventor: MASUDA KENJI
IPC: F16K17/18
Filed: 1980-08-11
Abstract: PURPOSE: To improve the stability of a relief valve at a high temperature by constructing the relief valve such that a pilot throttle almost in an orificelike shape is established between both abutting portions of a pilot poppet and a plunger upon relief operation so as to prevent a rate of vent-flow from being excessively increased.  
     CONSTITUTION: When fluid pressure transmitted from a pump port P through a through hole 23 to a pilot chamber 16 exceeds a value set by a spring 35, a pilot poppot 31 is forcedly separated from a valve seat 36, allowing a differential pressure corresponding to a rate of vent-flow through the hole 23 to be generated between the port P and the chamber 16. The leftward displacement of the plunger 20 overcoming a spring 22 due to the differential pressure causes both abutting portions 38, 41 of the poppet 31 and the plunger 20 to define therebetween a pilot throttle 44. Simultaneously, a main poppet 8 is displaced leftwards overcoming a spring 11 under action due to the combination of the difference between the left and right effective pressure areas of the main poppet 8 with the above-mentioed differential pressure so that the pump port P is opened to a tank port T for discharging fluid pressure into the tank port T.
