Title: Ignition device in internal-combustion engine
Inventor: WATANABE TAKESHI
IPC: F02P15/12
Filed: 1984-07-23
Abstract: PURPOSE:To enhance the ignition performance of an ignition device, by providing a capacitor which is charged by the voltage between both ends of a main current control transitor switch so that a cut-off control transistor switch is triggered when the charged current in the capacitor becomes zero to obtain an ignition operation. CONSTITUTION:When a voltage Ve in the direction of the arrow in induced through an ignition power source coil 1a in an ignition coil 1, a main current control transistor Tr 3 is turned on to effect a short-circuit current I1. Thereby, a condensor 5 is charged, and thereafter, when the voltage Ve exceeds its peak value, a trigger circuit 6 turns on a cut-off control transistor Tr 4. When the Tr 3 is turned off, the short circuit current I1 abruptly becomes zero so that a high ignition voltage is induced through a secondary coil 1b. Further, upon turn- on of the Tr 4 the electric charge of a capacitor 4 is discharged to the base of the Tr 4 through a positive feed-back circuit 7, and therefore, the Tr 4 is held in its turned-on condition while the Tr 3 is held in its turned-off condition, thereby the high ignition voltage is surely induced.

Title: Optical waveguide array and its manufacture
Inventor: HIDA MANABU
IPC: G03G15/04
Filed: 1990-06-08
Abstract: PURPOSE:To improve the resolution of a latent image formed on a photosensitive body by molding a two-dimensional distribution refractive index lens integrally at a light projection part. CONSTITUTION:The optical waveguide array 1 is formed on a substrate 8 and a layer 2 which has a refractive index distribution is sandwiched between two clad layers 4 and 5 which are low in refractive index; and the optical waveguide array consists of the part A of a normal optical waveguide array and a part B where the refractive index is distributed in the scanning direction (y direction) of light. Then, the two-dimensional distribution refractive index lens 6 is formed integrally at the part B while having a projection surface 7 with length L. Projection light can, therefore, be converged in a (y) direction by the optical waveguide array 1. Consequently, the resolution of the latent image formed on the photosensitive drum can be improved only by using an inexpensive converging means which converges the light at right angles to the projection light and scanning direction.

Title: Data transfer rate controller
Inventor: NAKAMURA YASUO
IPC: G06F13/12
Filed: 1993-06-23
Abstract: PURPOSE:To improve data transfer efficiency by preventing the occurrence of a data over-run fault due to the emptiness of a data buffer at the time of executing data transfer through a data buffer between a channel device and a peripheral equipment. CONSTITUTION:A monitoring circuit 1 monitors the using amount of a data buffer 5, and when it is less than a threshold value, a transfer rate changing circuit 2 instructs a transfer rate setting circuit 3 to decrease a transfer rate, and simultaneously instructs a transfer rate control circuit 4 of a peripheral equipment 20 to match the transfer rate of a channel device 10 with the transfer rate of the peripheral equipment 20. On the other hand, when the using amount of the data buffer 5 is larger than a threshold value the transfer rate changing circuit 2 instructs the transfer rate setting circuit 3 to increase the transfer rate. Thus, when the data buffer 5 is almost empty, the transfer rate is decreased, and the data buffer 5 can be prevented from being empty, and when the data buffer 5 is almost full, the transfer rate is increased, and the transfer efficiency can be improved.
