Title: Color demodulation signal generating circuit
Inventor: INOUE TAKAO
IPC: H04N9/45
Filed: 1994-01-24
Abstract: PURPOSE:To obtain a color demodulation signal generating circuit generating a color demodulation use chrominance subcarrier with a phase with respect to an external control voltage to set a hue of a color demodulation output independently of the dispersion in the circuit characteristic between products. CONSTITUTION:In the signal generating circuit generating a color demodulation chrominance subcarrier by adjusting a phase of the chrominance subcarrier synchronously with a color burst signal with an external control voltage, a phase comparator 2 is used to detect a phase difference between the chrominance subcarrier and the color demodulation chrominance subcarrier. Then a voltage comparator 4 is used to obtain a voltage difference between an error voltage corresponding to the phase difference and the external control voltage and a phase correction device 5 corrects a phase of the color demodulation chrominance subcarrier based on the voltage difference.

Filed: 1984-01-17
Abstract: PURPOSE:To obtain the titled device of high reliability by a method wherein an outer lead of a lead frame plated over with Ni or Ni alloy is partially Ag- plated, and the part other than the outer leads is resin-sealed after die and wire bonding. CONSTITUTION:The lead frame of Cu alloy or the like is Ni-plated 5 over before die-punching, and Ag-platings 6 and 7 are carried out to the inner leads 3 and the outer leads 4, respectively, by using Ni plating as the base.

Title: Voice coding device
Inventor: NAKAI NORIJI
IPC: H03M1/00
Filed: 1988-01-18
Abstract: PURPOSE:To accurately attain a predictive processing even if a voice with a high input level is inputted by predicting whether or not an overflow occurs in the middle of the operation of a coding processing, and using a result in which a prescribed constant is multiplied by an input voice waveform when the overflow occurs. CONSTITUTION:In a predicative parameter calculation block 3, input voice data xt is multiplied by a window function 21 and buffered by a buffer 22. A level check block 23 checks buffered data and decides whether the overflow occurs or not at the time of obtaining an autocorrelation value. When the overflow is predicted to occur, a value obtained by multiplying a value, which is obtained by dividing a mean value by a maximum value, is multiplied by data in the buffer, for example, and data is corrected. The autocorrelation value is obtained from corrected data in an autocorrelation calculation block 24 without the overflow. Thus, the linear predictive processing is accurately executed even if the voice with the high input level is inputted.

Abstract: PURPOSE:To obtain the titled compound useful for producing addition type imide resins, etc., in high purity at a low cost without using a dehydrating agent, by reacting an unsaturated dicarboxylic acid anhydride with a compound capable of forming an isocyanate compound at a reaction temperature. CONSTITUTION:A compound expressed by formula I (D is bifunctional organic group having >=1 carbon-carbon double bonds) is reacted with at least one of compounds expressed by formulas II and III (R1 is >=1C monofunctional organic group; R2 is >=1C n-functional organic group) in or without an organic solvent preferably at 20-200 deg.C, particularly 50-150 deg.C temperature to afford the aimed compound expressed by formula IV.

Title: Diaphragm water injection device in electrodeposition coating
Inventor: HAMAMOTO TOSHIAKI
IPC: G05D9/12
Filed: 1980-01-23
Abstract: PURPOSE: To simply control the diaphragm water injecting operation by a method wherein a liquid level sensor combined with the float in an electrodeposition tank is placed in the diaphragm chamber and a mechanism is installed to inject diaphragm water, following the variations in the liquid level in the electrodeposition tank.  
     CONSTITUTION: A float 11 is installed in the electrodeposition tank 1. The float support part 12 is used to support a liquid level sensor 13 in the diaphragm chamber at nearly the same level as the float 11. Detection signal P of the sensor 13 is input to controller 14 to control open/close of the diaphragm water injection valve 15. If diaphragm water level gets lower than the liquid level in the electrodeposition tank, then the sensor 13 separates from water level. By signal P, the controller 14 causes the valve 15 to open, and diaphragm water is injected into the diaphragm chamber 6. When the sensor 13 dips into water to the specified depth, the injection of diaphragm water is stopped. This enables diaphragm water level to follow and rise with the liquid level in the electrodeposition tank 1 within the specified range.

Abstract: PURPOSE: A two-layered enamel remover, containing aetone, and water and an oil as principal components, and usable properly in three applications of cleaning the nail surface, removing the enamel and treating the nail though a simple solution.  
     CONSTITUTION: A two-layered enamel remover containing acetone, water and an oil, e.g. octyl dodecyl oleate or octyl doceyl myristate. The oil in an amount of 0.5W10.0wt% is contained in an aqueous solution of containing acetone and water at a weight ratio of (95:5)W(80:20). In case an unnecessary nail enamel is removed, i.e. in the case of the rapid powerful removal of the enamel, a system 1 of the dissolved oil-water-acetone solution on the upper layer part is used. In the case of the ordinary enamel removal, a container is shaken to make an oily layer 2 settling in the bottom part of the container fine oily droplets 3 which are dispersed in all the solution. Thus, the enamel can be removed with the preventing effect on degreasing. In case the oil must be supplied to retain the emollient effect of the nail, the container is reversed and the settled oil 2 is taken out of the mouth of the container.

Title: Automatic frequency adjustment circuit
Inventor: MIYAMOTO HIROKI
IPC: H04N5/50
Filed: 1995-01-20
Abstract: PURPOSE: To improve the video output characteristic of an automatic frequency adjustment circuit(AFT) by eliminating the DC offset of the error voltage of a phase locked loop(PLL) and a comparison voltage. CONSTITUTION: The DC offset of the output of a phase detector APC 2, that is, the offset between a loop filter voltage Vin and a comparison voltage Vref is not produced. Thus, a current mirror circuit using an NPN transistor(TR) is not employed for the output of the APC 2 and a Vref is generated from the APC 2. Each current is set as IB=IC=1/2IA. Thus, the relation of Vin=Vref is always established in terms of DC. The Vref is always equal to DC by summing them. Since the gain of the APC 2 is halved when the current IA is the same as that of a conventional circuit, the IA of this circuit is twice that of the conventional circuit. The output of an AFT 6 is always a center voltage when the frequency is fo by eliminating the DC offset in this way to match a free-run frequency of a voltage controlled oscillator VCO 3 with the frequency of accurately.
