Title: Intake device for diesel engine
Inventor: ARISAWA YOSHIHIKO
IPC: F02F1/42
Filed: 1989-01-20
Abstract: PURPOSE:To make the whole side of an engine compact, and while reduce the number of parts and improve the rigidity by integrally forming two intake connecting passages in the wall of a cylinder block. CONSTITUTION:The second intake connecting passage 18 for connecting an intercooler 10 and each intake port 22 and the first intake connecting passage 17 for connecting a supercharger and the intercooler 10 are integrally formed with a cylinder block 1 in the wall of the cylinder block 1. Thereby, the projection to the outside is eliminated in comparison to the connecting part pipe arrangement, and the whole of an engine is compactized. Since an external connecting pipe supporting device, etc. with the complex structure is eliminated, the number of parts is reduced. Further, the rigidity of the cylinder block 1 is improved to reduce the engine vibration and the noise caused by it.

Filed: 1989-01-20
Abstract: PURPOSE:To save excess energy unnecessary for running so as to be utilized effectively by providing a fly-wheel, a clutch and a clutch operating means as well as a speed change gear for adjusting the rotating speed between the fly-wheel and a wheel. CONSTITUTION:When the speed of a bicycle is increased more than necessary during running, a clutch 8 is operated by means of an operating lever 9 to cut off power transmission between a rear wheel 5 and a fly-wheel 10, change the gear ratio of a speed change gear 6 over to the side where the fly-wheel 10 is further accelerated by the operation of the operating lever 7 and connect the clutch 8 again, and thus the speed is reduced appropriately and the fly-wheel 10 is further accelerated so as to save energy. On the other hand, when the energy applied to a pedal 1a by a rider does not satisfy the necessary energy for running, the clutch 8 and the speed change gear 6 are operated to change the gear ratio over to the side where the rear wheel 5 is accelerated, so that the speed is temporarily increased instead of decelerating the fly-wheel largely, and thus running is kept up.

Title: Gas ignition device
Inventor: AOKI AKICHIKA
IPC: F23Q3/00
Filed: 1986-01-22
Abstract: PURPOSE:To keep the unburned gas which is released until ignition to minimum by providing a high-tension spark generating section to each of a plurality of gas burners and igniting all the gas burners by the high-tension spark generating sections. CONSTITUTION:A high-tension generating section 13 is operated by a control block 16 which controls gas ignition. When a high tension is applied to a high- tension spark section 12, sparks are generated at the air gaps 12a... at the high-tension spark section 12. These sparks are kept generating from a few seconds earlier than the jetting out of a gas from each gas burner 11. Next, the gas flows from the control block 16 to each of the gas nozzles 15 to supply the gas to each burner 11. With this constitution, the gas which flows to the gas jetting section of each gas burner 11 contacts the sparks and it is ignited. Accordingly it is possible to keep the unburned gas until it is ignited to minimum, and the misunderstanding that the unburned gas is due to an accident of gas leakage can be avoided.

Filed: 1989-01-20
Abstract: PURPOSE:To attain simultaneous setting of a bit length and a shift stage number by providing a selector to 2nd and succeeding stages of registers respectively in a multi-stage register and inputting an input signal to each register and an output signal of a preceding stage of register selectively. CONSTITUTION:An input selector 3 sets m-set of bits in B1 - BN from the B1 and inputs them to N-set of registers 11 - 1N as a signal. Selectors 22 - 2N corresponding to registers 22 - 2N select an input signal of the corresponding register and an output signal of the preceding stage with a control signal and input the result. In the case of a bit number (m), the selectors up to 2m select input signals up to Bm and the succeeding selectors select an output signal of (m-1) preceding register respectively to shift the m-bit input signals B1 - Bm by up to N/m stages. Thus, a variable shift register setting simultaneously both the bit length and the shift stage number is obtained.
