Title: Printed wiring board with metal plate
Inventor: KONNO TATSUHIKO
IPC: H05K3/34
Filed: 1992-02-26
Abstract: PURPOSE:To make possible efficient manufacture featuring improved heat dissipating performance and increased accommodating amount of wiring by connecting individual dummy conductors mounted on both sides of a printed wiring board through a galvanized through-hole. CONSTITUTION:A heating electronic parts 9 such as IC or LSI is fixed on a wiring layer 4 through a lead wire 10 with the use of a solder 11, and is mounted on a dummy conductor 2 in direct contact condition. Therefore, heat generated from the electronic parts 9 is dissipated from a metal plate 8 through the dummy conductor 2 and a heat transmitting through-hole 3 for heat transmission use. The dummy conductor 2 and the heat transmitting through-hole 3 are provided individually at the same time when a wiring layer 4 and a through- hole 5 are provided. When both sided printed wiring board is used for a printed wiring board 1, the printed wiring board having more than 2 layers can be used. Therefore, performance of the electronic parts 9 is not deteriorated, because heat dissipating performance is excellent in the printed wiring board equipped with a metal plate 1.

Abstract: PURPOSE:To prevent the generation of fading and to obtain a uniform image by development. CONSTITUTION:A resin film layer 10 formed by dispersing the fine particles of crystalline graphite into a resin is formed on the surface of a developing sleeve, by which the inclination gamma of the curve to measure the work function on the surface of the sleeve 2 is specified to >=10 (cps/eV). Then, the above- mentioned gamma corresponds to the exposing ratio of the graphite particles on the surface of the film layer 10 and corresponds to the capacity to impart a triboelectostatic charge to a one-component developer and the slipperiness of the surface of the sleeve 2. The capacity to impart the electrostatic charge and the slipperiness of the surface are high at >=10gamma and, therefore, the developer can be well electrostatically charged and the regulation to prohibit the passage of the developer of the low charge by a blade 6 is possible. Only the normally charged developer can then be passed and used for development. Then, the fading arising from the lack of the charge of the developer is eliminated.

Title: Optical information reproducing device

IPC: G11B7/005
Filed: 1987-02-23
Abstract: PURPOSE:To ensure the accurate detection of levels by converting the output of a pulse generating means into a read pulse that provides the timing of a peak point for the change of the reflected light quantity. CONSTITUTION:A differential signal 102, i.e., the output of a differentiator 11 used for detection of a peak point is used to detect a level in order to assure the presence of the change of the reflected light caused by a pit. Thus, it is possible to eliminate the influence of the waveform distortions caused by the fluctuation of the DC level of a read signal or by the second order differentiation. At the same time, the detection due to noises, etc., can be avoided. Thus, it is possible to detect the timing of an accurate peak point and to perform the reproduction of information with high reliability.
