Title: Programmable delay circuit
Inventor: EJIRI MASAHARU
IPC: H03K5/135
Filed: 1984-12-24
Abstract: PURPOSE:To change a delay time and a signal width without changing the circuit by using a delay circuit possible for programming the delay time and the signal width. CONSTITUTION:A unit signal generating circuit 5 receiving an output of a program command circuit 4 generated to program optionally the delay time and the output signal width generates a unit signal US. After the unit signal US is corrected by a correction circuit 6, the result is inputted to a relative value generating circuit 8. The circuit 8 receives an output of the circuit 4 to set the outputted delay time and signal width according to the relative value with a basic clock CKS.

Title: Device for controlling ignition timing for engine
Inventor: UCHIUMI IWAO
IPC: F02P5/10
Filed: 1985-12-03
Abstract: PURPOSE:To prevent the generation of combustion noise by reducing the quantity of lead angle of ignition timing at the time of EGR when the quantity of intake of new air becomes above a certain value. CONSTITUTION:When a throttle valve 3 is slightly opened from its totally closed condition, an intake negative pressure acts on a first negative pressure sensing port 10 as well as a second negative pressure sensing port 11. Thereby, since the intake negative pressure acts on the negative pressure chamber 6a of an actuator 6, an EGR valve 5 is opened to carry out EGR while, since the intake negative pressure also acts on the second negative pressure chamber 8d of an actuator 8, the angle of lead of an ignition timing is largely advanced accompanying the EGR. When the throttle valve 3 is further opened, since the intake negative pressure acts on a third negative pressure sensing port 12, the negative pressure is fed to the negative pressure chamber 18a of the actuator 18, causing the valve body 15a of a selector valve 15 to be displaced downward. As a result, the second negative pressure chamber 8d of the actuator 8 is released to the open air, correcting the lead angle of ignition timing accompanying the EGR to be small.

Abstract: PURPOSE:To achieve increased specific surface area and improved gas diffusion of gas diffusion electrodes for a fuel cell of the molten carbonate type by adjusting the diameters of the small holes of the gas diffusion electrodes to have two peak levels larger and smaller than the mean diameter of the small holes of the electrolyte matrix respectively. CONSTITUTION:After minute nickel particles are kneaded and sintered to prepare secondary particles, they are then slightly pulverized and the prepared pulverized nickel is subjected to grading. Next, a binder is kneaded into the graded pulverized nickel to make a paste which is then applied to an electrode base and then the formed body is sintered, thereby making each of gas-diffusing electrodes to be placed on the surfaces of the electrolyte layer of a molten- carbonate-type fuel cell. The diameters of the small holes of the gas-diffusing electrodes are adjusted to have two peak levels larger and smaller than the mean diameter of the small holes of the electrolyte layer respectively. Accordingly, it is possible to simultaneously satisfy the contrary characteristics of increasing the specific surface area and improving the gas diffusion, thereby increasing the utilization rate of reaction gas.
