Abstract: PURPOSE:To decrease exfoliation of thin film forming a core by laminating alternately a high permeability thin film and a nonmagnetic thin film having the same degree of a thermal expansion coefficient so as to form the core part thereby decreasing the generation of the internal stress at manufacture. CONSTITUTION:A high permeability alloy thin film 3 such as ''Sendust'' and the nonmagnetic thin film 4 having electrical insulation are laminated alternately on a substrate 1 such as crystallized glass by using the sputtering so as to form a multi-layered magnetic substance layer 2. The coefficient of thermal expansion of the nonmagnetic material at 50 deg.C-600 deg.C used for the nonmagnetic thin film 4 is nearly 145-150X10<-7>/ deg.C, which is similar to that of the ''Sendust''.

Title: Illuminating plate
Inventor: YAMAMOTO KUNITOSHI
IPC: G02F1/133
Filed: 1986-06-30
Abstract: PURPOSE:To execute an almost uniform surface light emission by constituting the titled plate so that light beams having a high luminance among light beams from a light source transmits through a part where an occupied rate of a printing film per unit area is large, of a light transmissive plate, and on other hand, light beams having a low luminance transmit through a part where occupied area rate is small. CONSTITUTION:In a part where light beams having a high luminance transmit through, of a transparent plate 1, an occupied area rate of a printing film 2 is large a gap through which the light beams transmit through is small, therefore, the transmissivity of light beams from a light emission diode 4 is deteriorated, and a luminance of a transmission light beam drops. On the other hand, in a part where light beams having a low luminance transmit through, of the transparent plate 1, the occupied area rate of the printing film 2 is small and the gap through which the light beams transmit is large, therefore, the transmissivity of the light beams from the light emission diode 4 is good, and the light beams from the light emission diode 4 hold its luminance roughly as it is and transmit through, and also, reflected light beams which have been reflected by a reflecting plate 3 transmit through the part corresponding to the peripheral part of the light emission diode 4 of the transparent plate 1. In this way, an almost uniform surface light emission can be executed extending over a wide range to not only the part opposed to the light source but also the part corresponding to the peripheral part of the light source.

Filed: 1977-12-26
Abstract: PURPOSE: To improve the linearity of the gain-controlled output signal as well as to reduce the power consumption of the circuit by setting the output impedance of the constant voltage source to a fixed low level regardless of the input signal.  
     CONSTITUTION: The input signal to be supplied to the base of transistor TR11 is voltage-divided by the emitter output and via resistance 12 and 18 plus TR19 to be supplied to the base of TR20. Accordingly, the internal impedance of TR20 is varies by the input signal, and the collector current is controlled by the input signal with its scale proportional to the input signal current. Then the input signal level increases, and the internal impedance of TR20 is lowered by the increment of the signal current flowing through gain variable resistance 13, with no change of the emitter potential and current given to TR14. As a result, the power consumption can be reduced for the circuit without imparing the linearity of the gain-controlled output signal.
