Filed: 1993-04-19
Abstract: PURPOSE:To improve the transparency of an electromagnetic wave shielding body without deteriorating the intrinsic important function of the shielding body by respectively coating counterposed transparent substrates with fluorine- doped tin oxide films having specific surface resistances. CONSTITUTION:The shielding body 30 is constituted by putting together two transparent substrates 10 at least one surfaces of which are with fluorine-doped tin oxide films 12 with an intermediate 14 composed of polyvinyl butyral (PVB), etc., in between so that the shielding body can exert the function of an electromagnetic wave shielding body. In addition since the difference in refractive index between the film 14 and film 12 is relatively small, because the film 14 is deformed and fill up the rugged surface of the films 12 when the film 14 is stuck to the films 12, the haze value becomes smaller and the transparency of the shielding body can be improved. When the films 12 are constituted so that the surface resistance of the films 12 can fall with the range of 8-12OMEGA/square, especially, the function of the shielding body 30 can be further improved.

Abstract: PURPOSE: To enhance the efficiency of heat exchange of a condenser by providing the condenser in which one straight pipe comprising a metallic pipe and heat radiating plates brought into thermal contact with the metallic pipe is bent plural times on the same plane and which is arranged on a mounting plate forming a machine chamber in such a manner that the heat radiating plates are made substantially horizontal with respect to the mounting plate. CONSTITUTION: A condenser 1 is formed of one straight pipe comprising a pipe and heat radiating plates, which are brought into thermal contact with the pipe, and the heat radiating plate are mounted perpendicularly relative to the metallic pipe. This straight pipe is bent plural times on the same plane to form one condenser 1. The condenser 1 is arranged so that the heat radiating plates at the linear portions are made substantially horizontal with respect to a mounting plate 7. In this case, cold air blown from a fan 13 is put into a condition of a violently turbulent flow, and a heat radiating effect due to the turbulent flow is promoted on the surface of the condenser 1, while the condenser 1 is prevented from being covered with dust with the aid of the turbulent flow.  Cold air thus introduced cools a compressor 6 after exchanging heat with the condenser 1 and is discharged through an air outlet port.

Accordingly, it becomes possible to adjust the favorable electrical separation between fellow N<+>-type high density buried layers 30 by the concentration of the buried layer P1 and the short channel property of a MOS transistor by the buried layer P2, independently. Hereby, even in case that a short channel MOS transistor 80 is formed on a chip together with a high-speed bipolar 70, the concentration of the buried layer P1 need not be raised, so the increase of the side face components of substrate capacity can be suppressed, and the substrate capacity is not increased, and the high-speed property of the bipolar transistor 70 is not lost.

Title: Horizontal synchronizing signal generating circuit
Inventor: OOISHI TOMOFUMI
IPC: H04N5/08
Filed: 1987-04-14
Abstract: PURPOSE:To obtain a more stable horizontal synchronizing signal without pseudo synchronizing signal and with less jitter component by weighting a horizontal synchronizing signal separated from a synchronizing separator circuit for each one horizontal scanning time, summing the result and averaging it timewise. CONSTITUTION:A horizontal synchronizing signal S1 separated and binarized from the synchronizing separation circuit is sampled by a basic clock at a flip-flop 1 and added to a feedback signal S3 at an adder 2 synchronously. After the output of the adder 2 is retarded by a 1H delay section 3, the result is inputted to a feedback section 4 and a comparator 5. A weight alpha is applied to the signal S2 after 1H delay and a feedback signal S3(S3=alphaXS2) is outputted. That is, the negative feedback loop is formed by three devices, the adder 2, the 1H delay section 3 and the feedback section 4 to average the synchronizing signal S1 timewise. Thus, the pseudo synchronizing signal generated irregularly is eliminated, and jitter component is reduced and the effect of impulse noise is absorbed.
