Title: Terminal equipment for cable television receiver
Inventor: OZAWA KAZUMASA
IPC: H04N5/00
Filed: 1990-11-15
Abstract: PURPOSE:To suppress a maximum output level to a standard level or below at installation by connecting an output control circuit to a mixer output, connecting a level adjustment device to a control input terminal of the output control circuit and connecting an output terminal to an output of the output controller. CONSTITUTION:A selected signal is converted into a specific channel by a 2nd mixer 16 and outputted to a television receiver from an output terminal 24. Then in this case, a cable television signal having a maximum output level is received and an adjustment section 28 of a level adjustment device 21 is adjusted through an adjustment window 30 by using a jig such as a screw driver so that its output signal is lower than a specified level. After the adjustment above, a leg 31 is covered to the window so that the adjustment value is changed due to the contact with the adjustment section 28 of the level adjustment device 21.

Title: Manufacture of semiconductor laser
Inventor: SUGIMOTO MITSUNORI
IPC: H01S5/34
Filed: 1988-12-08
Abstract: PURPOSE:To obviate thermal transformation of a quantum well of a mesa stripe and leakage of current at an unrequired P-N junction during diffusion of Si by reusing a mask which has been used for formation of the mesa stripe as a mask for lift-off of an Si film. CONSTITUTION:After a mesa stripe 9 is formed by etching, Si is diffused into the regions other than the mesa stripe 9 so that an Si layer 10 is formed on an active layer 4 and a quantum well is made disordered. Since the depth to which Si is to be diffused is decreased by the etching, there is no need of performing high-temperature heat treatment for a long period of time. Further, since Si as an N-type dopant is used for the LD structure on the N-type substrate 1, the area of an unrequired P-N junction can be minimized. Si is vapor deposited with a photoresist mask 8, and then the stripe mask is dissolved to remove the Si deposited thereon. Accordingly, the diffused Si can be patterned in a self-aligned manner only on the bottom of the mesa stripe. ln this manner, a semiconductor laser can be manufactured with high yield.

Abstract: PURPOSE:To avoid the deformed color balance by providing AGC detection circuit and an AGC amplifier circuit inputting an output of an AGC voltage sampling and holding circuit inputting an output of the AGC detection circuit to its control terminal so as to obtain a picture with proper lightness automatically even when the lightness of an object is changed. CONSTITUTION:An achromatic filter having an average transmittivity of each color filter 4 is placed in front of a lens 2 to pick up an object. With the AGC voltage sampling and holding circuit 11 kept to the hold release state in this case, the AGC circuit is operated and a video signal with a proper level is obtained. Then the AGC voltage sampling and holding circuit 11 is kept in the holding state, each color filter 4 is placed sequentially in front of the lens to fetch each color video signal into a picture memory 9. Since the AGC voltage is fixed, the gain of the AGC amplifier circuit is constant and the color balance is not unbalanced. Furthermore, an automatic dimmer circuit 15 is used to activate similarly the sampling and holding of the dimmer voltage, then a video image with a proper lightness is obtained even from an object with any luminous quantity.

Title: Voice signal processor
Inventor: MIURA MASAMI
IPC: G10L21/0316
Filed: 1992-10-26
Abstract: PURPOSE:To prevent the degree of clearness from being lowered by suppressing an amplitude for a prescribed time before a time point when the vowel block of a voice signal compressed in the amplitude level is finished. CONSTITUTION:A voice analysis part 2 detects the vowel block of the digital voice signal compressed with the amplitude level with a linear predictive analysis method or a PARCOR analysis method, detects the end of the vowel block and outputs an end detecting signal. On the other hand, the digital voice signal is stored in a voice memory 4 as it is. When a CPU 3 receives the end detecting signal from the analysis part 2, voice data in the memory 4 are read out, a control for decreasing the amplitude or turning it to '0' is performed for (t) milli-seconds before the end of the vowel block, and a voice control command signal is outputted to a D/A converter 5 later. This signal is converted to an analog signal by the converter 5 and outputted from a voice output signal 6 as a completely processed regenerative voice signal. Thus, the degree of voice clearness can be prevented from being lowered.

Title: Output circuit
Inventor: TANIGUCHI HITOSHI
IPC: H03K19/00
Filed: 1987-12-09
Abstract: PURPOSE:To improve high speed performance without deteriorating noising resistance characteristic by providing a control circuit applying a voltage turning on a MOS transistor(TR) to the gate of the MOS TR till a gate voltage reaches a value close to a threshold value when the MOS TR is going to be turned on. CONSTITUTION:A NOR circuit 2 detects it that an output of a NAND circuit changes from a 'high' to a 'low' level and the output of a inverter INV 2 has to be switched from a 'low' level into a 'high' level. The output turns on a pull-up MOS TR Q4 to pull up a gate of an output MOS TR Q2 at a high speed. When the level of the gate of the MOS TR Q2 is nearly equal to a threshold voltage Vth, the NOR circuit NOR 2 turns off a pull-up MOS TR Q4. Thus, the time tau requiring to turn on the MOS TR Q2 is reduced. Then the operating speed of the MOS TR Q2 is quickened without generating any noise.
