IPC: G02F1/13363
Filed: 1986-02-05
Abstract: PURPOSE:To permit liquid crystal display of high contrast by forming a transparent substrate into multi-layered structure having >=2 layers of high-polymer material layers and laminating two layers of the high-polymer material layers in such a manner that the optical axis directions thereof coincide with each other or intersect approximately orthogonally with each other.

Title: Am detecting circuit
Inventor: YOKOYA SATOSHI
IPC: H03D1/22
Filed: 1982-02-15
Abstract: PURPOSE:To obtain effectively an output of AM detection with an AM detecting circuit using a PLL circuit even in case the level is considerably low for a signal to receive an AM modulation. CONSTITUTION:A signal to receive an AM modulation which is supplied from a high frequency amplifier 2 is supplied to a phase comparator 4 through the 1st gate circuit 11. The output of the comparator 4 is fed to an AC amplifier 14. The output of the amplifier 14 is supplied to an LPF5 via the 2nd gate circuit 12. The circuit 11 samples the signal to receive an AM modulation with the oscillation output of an oscillator 13. A differential proportional to a signal component like a waveform B emerges at the output side of the comparator 4 even in case the level is considerably lower than the DC offset voltage for the signal to receive an AM modulation. This differential is amplified by the amplifier 14 up to such a level at which the DC offset voltage is neglected. This output of amplification (waveform C) undergoes a synchronizing waveform detection through the circuit 12 which is turned on and off synchronously with the circuit 11. Thus an output like a waveform D is obtained.

Title: Cooling device utilizing heat pipe
Inventor: HATA RYOSUKE
IPC: H01L23/427
Filed: 1985-02-06
Abstract: PURPOSE:To improve the efficiency of heat dissipation by isolating a high temperature section and a low-temperature heat dissipating section for a heat pipe in a box body, dampening a fin for heat dissipation for the low-temperature heat dissipating sectoin with water and forcibly vaporizing moisture when the heat pipe is coupled with a semiconductor in a termal conductive manner. CONSTITUTION:When the operation of a semiconductor 1 is suspended, a damper 12 for a box body 6 segregates a high temperature section and a low-temperature heat dissipating secton for a heat pipe 3, and prevents an intrusion to the high temperature section side of moisture on the low-temperature heat dissipating section side. An electric fan 10 is turned at the same time as the operation of the semiconductor 1, the velocity of air is adjusted while opening the damper 12 by air sucking in through a filter 18, and air is discharged through the low-temperature heat dissipating section. The vaporization of a water conducting material 15 is promoted by air passing through the low-temperature heat dissipating section during that time, and the heat pipe 3 quickly dissipates a large amount of heat in the low-temperature heat dissipating section. Accordingly, constitution in which a cooling device is isolated from the cooled electrical apparatus side is adopted, thus allowing safety operation at all times, then also removing energy required for operation.

Filed: 1990-02-01
Abstract: PURPOSE:To prolong the lifetime of a flange and prevent bad effects on a semiconductor substrate by providing liquid receivers on the section, on which a reaction gas or reaction product condenses, in a silica tube. CONSTITUTION:Gas introduced ion a silica tube 3 through a gas introduction pipe 5 travels downward as it flows, processes a semiconductor substrate 1, reacts, and is exhausted through an exhaust pipe 6. A part thereof remains on a flange and a reaction gas or reaction product of a certain character condenses because the flange 7 is cooled.

Title: Wireless microphone unit
Inventor: KOUTANI YUTAKA
IPC: G03B31/00
Filed: 1979-02-28
Abstract: PURPOSE:To prevent the momentary audio volume increase due to overmodulation or to prevent noise, by providing the mens quickering the operation stop of the high frequency circuit due to the disconnection of power switch by means of the operation stop of audio circuit. CONSTITUTION:The attenuation means for the audio amplifier output consisting of transistors TrQ1, Q2 and resistors R3-R6 is provided. Further, when the push button 10 is detached and the switch 109 is OFF, the audio circuit 103 is gradually inoperative according to the discharge of the capacitor C1. On the other hand, the capacitor C2 is small and the charging from the capacitor C1 is blocked with the diode D1, then the charged charge of the capacitor C2 is momentarily discharged and the high frequency circuit is momentarily inoperative. Further, since the discharge of the capacitor C2 is faster than that for C1, the base potential of TrQ1 is lowered with the discharge of the capacitor C2, TrQ1 is conductive and Q2 is conductive. Thus, the output signal of the circuit 103 is attenuated with the resistor R3 and TrQ2 and the supply to the modulator 105 is interrupted. That is, since TrQ2 is ON with the siwtch 109 turned off, audio signal is attenuated and momentary noise recording can be prevented due to overmodulation in a short time from the switch OFF to the inoperative high frequency circuit.

Title: Thermosetting resin molding material

IPC: C08K7/00
Filed: 1983-02-15
Abstract: PURPOSE:The titled material capable of providing a molding of a low bulkiness and excellent impact resistance, containing a specified amount of a glass fiber of a short fiber length. CONSTITUTION:A thermosetting resin molding material containing 5-70wt% glass fiber of a fiber length of 0.15-1.3mm.. A glass fiber-containing thermosetting resin molding material is excellent, for example, in that it can form a molding of excellent impact resistance. However, because chopped strand glass fiber of a long fiber length is used conventionally, there is a drawback that such a material becomes bulky when granulated because of its rigidity. The use of the glass fiber of the above fiber length in the above amount makes it possible to eliminate such a drawback and to obtain a molding material capable of forming a molding of a low bulkiness and sufficient impact resistance.
