Title: Side-unnecessary image erasing device of electrophotographic copying machine
Inventor: TAKATOU AKIHIRO
IPC: G03G15/043
Filed: 1984-04-03
Abstract: PURPOSE:To suppress variation in side-unnecessary image erasure range and to reduce the manufacture cost of the device by selecting and using only the light emitting diode with selected characteristics which is arrayed at the innermost side among light emitting diodes to be turned on. CONSTITUTION:An ISIL assembly 21 formed by arraying, for example, 61 light emitting dioes L1-L61 in a main scanning direction in parallel, a constant current source 22 which supplies constant currents to L1-L61 independently, and a drive controller 23 which controls the on-off states of L1-L61 are provided. In this case, only L2, L44, L50, and L60 have uniform characteristics and normal diodes are usable as the remaining 57 diodes. When a form of B4 size is used and the specified size of the drive controller 23 is B4, only the light emitting diodes L1, L2, L60, and L61 are turned on by the constant current power source and a defective image is erased by receiving light from them. At this time, the diodes positioned at the innermost side among light emitting diode which are on are L2 and L60, so the variance of the distribution of the quantity of image decreases extremely. Further, L2 and L50 correspond to A4 size. Consequently, the manufacture cost of the device is reduced.

Title: Optical fiber, optical fiber sheet and image transmitting fiber device
Inventor: IKEGAMI KIMIKO
IPC: G02B6/44
Filed: 1983-04-14
Abstract: PURPOSE:To raise a transmission light quantity, and also to raise an effective sectional area by using a light transmitting member whose section has a roughly polygonal shape, for a core of an optical fiber. CONSTITUTION:A core 1a consists of a quartz compound glass fiber having a square section whose one side is 1mum. A clad 2a protects the outside circumference of the core 1a, and also consists of a quartz compound glass being a regular square whose outside size is 30mum as to its one side since the core 1a forms a total reflecting surface. A refractive index of the core 1a is made larger than a refractive index of the clad 2. In this way, a light which is made incident to one end of the core 1a is reflected totally in the core 1a and sent out efficiently to the other end. In this case, since the sectional shape of the core 1a is square, the quantity of a light to be transmitted can be raised by 21.5%, comparing with a conventional one having the same diameter. Also, it is possible to arrange this optical fiber in one line and use it in the shape of a sheet.

Title: Rs flip-flop circuit
Inventor: NAGATOMO KAZUO
IPC: H03K3/356
Filed: 1987-03-23
Abstract: PURPOSE:To reduce the higher harmonic component by providing a filter circuit to absorb higher harmonic components between an operating voltage source and a connecting point of both loads and an output of a differential amplifier corresponding to each load. CONSTITUTION:Capacitive elements 6, 8 and a connecting means 12 act like a filter circuit 14. Thus, in operating the circuit at a comparatively lower frequency than the design operating frequency, the higher harmonic component due to the unstability caused by staying before and after zero crossings for a comparatively long time is absorbed via the capacitive elements 6, 8 and the connection means 12. That is, the production of the higher harmonic components in the state 1 are suppressed via the capacitive elements 6, 8 and the connection means (capacitive element) 12 and the generation of the harmonic component in the state 2 is suppressed via the capacitive elements 6, 8 and the connection means 12. Thus, the production of output signal distortion is suppressed.

Title: Semiconductor laser and manufacture thereof
IPC: H01S5/00
Filed: 1992-03-25
Abstract: PURPOSE:To obtain a semiconductor laser having no n-type semiconductor layer of severe forming conditions, a high efficiency and a high speed modulability by forming a band discontinuous heterojunction to become a barrier of high energy for other carrier in a boundary between high resistance semiconductor layers formed at both sides of a light emitting region and a cap layer. CONSTITUTION:A valence band difference of a heterojunction between a high resistance InP layer 17 and a p-type GaInAs cap layer 18 becomes a high barrier for holes. The barrier suppresses introduction of holes from the cap layer to a high resistance InP layer 15. Electrons of carrier from an n-type InP substrate are collected to a deep level of the layer 17, and not combined with the holes. Carrier injected to an upper part of a current blocking layer of the cap layer is easily moved to an active region to effectively contribute to a light emission. Since an operation of the barrier for the holes is incorporated in the layer 18 for flattening an element in a semiconductor laser, a structure is simplified by an amount having no n-type semiconductor layer.
