Title: Shock absorbing device of diesel engine
Inventor: NAGANO HIROYUKI
IPC: F02B23/04
Filed: 1982-02-01
Abstract: PURPOSE:To reduce a knocking phenomenon of a Diesel engine at its low speed revolution, by providing shock absorbing valves, which relax an impulsive sound and vibration of explosion at low speed revolution, to a cylinder head of the Diesel engine. CONSTITUTION:A shock absorbing valve 1 operated at fixed pressure is mounted to a cylinder head 9 of a Diesel engine. The valve 1 is arranged such that tension of a spring 2 is a little larger than compressive pressure. If fuel is burned and exploded in a cylinder, high pressure of explosion gas is applied to the valve 1 to instantaneously press the spring 2 and partially absorb the explosion gas in a shock absorbing chamber 5. And then as pressure of the gas decreases, stored energy of the spring 2 is returned to the side of a piston 6 through the explosion gas. A fixing rod 3 is lowered at high speed revolution of the engine to fix the valve 1.

Abstract: PURPOSE: To provide an arrow feather shaped jack type guy anchor which is easy to drive in, large in tension resistance and free from the unuseful wear of component parts by a structure wherein the principle of jacks is used to expand the two arrow feather shaped plates driven into the ground.  
     CONSTITUTION: The arrow feather shaped jack type guy anchor is set upright and driven into the ground with the beat portion thereof beaten by means of a drop hitter for example. The anchor can be easily driven up to a desired depth because the resisting plates 1 are of an acute angle arrow feather tip and form an acute angle with each other. Next, a rotary spindle 4 is rotated so that the screwed portion 8 engaging therewith is lowered along thread and the plates 1 are expanded by expanding arms 9. The spindle 4 is rotated further even after the plates have  reached a desired expansion degree so that the serewed portion 8 contacts with a  beat portion 3 and rotated further on so that the shaft 4 is raised and prevented  from slipping out of a fitting hole 2. When rotation is made further, the spindle 4  can be pulled off from a guy anchor with a pin 6 cut.

Abstract: PURPOSE: To improve constructing performance by providing an upper frame or the indoor side upper face of a longitudinal frame and a lower frame or the indoor side lower face of the longitudinal frame with inclination along the inclined face of wedges, and driving the wedges into the inclined parts to temporarily fix a sash to an opening part. CONSTITUTION: The upper face 22 and lower face 42 of a sash 1 are provided with inclined cutouts at corner angular parts or the like so as to make wedges 5 enter easily. Since the upper face 22 and lower face 42 come in face contact with the inclined faces 51 of the wedges 5, contact area is enlarged, and force from the inclined faces 51 can be received by the faces so as to heighten the stability of the wedges 5. The wall thickness of the respective wedge 5 side upper parts and lower parts of indoor pieces 21, 41 is made thicker than the other parts so as to heighten resistance to flexural deformation at the time of driving and pulling out the wedges 5. Clearances for receiving the wedges are thereby formed between the sash and a building frame to make the wedges enter easily, and the damage of the sash can be also prevented since there is no need to drive the wedges hard.

Title: Oscillating device
Inventor: MIZUTANI SHIROU
IPC: H03B5/12
Filed: 1982-02-03
Abstract: PURPOSE:To obtain an oscillating device which has stable oscillations although the deviation is large among various types of circuit elements, by adding a circuit element which has no fault even when a circuit is converted into an IC. CONSTITUTION:The common point of connection between the base of a transistor (TR)1 and the collector of a TR2 is connected to the line of a reference power supply VCC connected with a reference power supply terminal 8 via a resistance 12 of the same reference value as a resistance 11. As a result, the DC load is balanced for a differential amplifier containing TRs 1 and 2, and therefore the DC working point is always set at the center of an active region. This prevents the reduction of DC gain. Thus no increment is caused to (rmin) unlike a conventional oscillating device although the values R11 and R12 of resistances 11 and 12 are increased up to about 200OMEGA for example. Then an oscillating device has oscillations with an extremely small value of (r). In such a way, an extremely stable oscillating circuit is obtained with addition of the R12 which is equal to the R11.
