Title: Manufacture of nonvolatile semiconductor memory
Inventor: OOMORI KIYOSHIGE
IPC: H01L21/8247
Filed: 1993-11-11
Abstract: PURPOSE:To improve the deterioration of the insulating property of a nonvolatile semiconductor memory by forming an HTO film on the surface of a semiconductor substrate including floating gates and side-wall spacers on the side walls of the floating gates, and then, a control gate on the surface of the substrate including the floating gates and side-wall spacers. CONSTITUTION:After forming floating gates 5 on a semiconductor substrate 1 having LOCOS oxide films 2 and gate oxide films 4 by patterning a polysilicon, oxide film, and nitride film, an HTO film 9 is formed on the surface of the substrate 1 including the gates 5. Then side-wall spacers 9a are formed on the side walls of the gates 5 by etching back the film 9. After forming the spacers 9a, a control gate 10 is formed on the surface of the substrate 1 including the gates 5 and spacers 9a. Therefore, a sufficiently large thickness can be secured for an interlayer insulating film between the gates 5 and gate 10.

Title: Method and device for cutting processing
Inventor: AOYANAGI MINORU
IPC: B23D55/04
Filed: 1998-10-05
Abstract: PROBLEM TO BE SOLVED: To move a table back to the original position without bringing the front end of a work into contact with a sawtooth after completing cutting processing. SOLUTION: A work W is placed on a table 23 which reciprocates along the right and left direction to a sawtooth BS. The work W is clamped by a clamp device 39 provided in a cutting width positioning device 41, the clamp device 39 moves forward to almost cross to a cutting line CL of a sawtooth BS in a right angle direction on the table 23 and the cutting position of the work W is positioned in the cutting line CL of the sawtooth BS. After the table 23 moves forward in the direction of the sawtooth BS and the work W is cut and processed, and after the clamp device 39 moves forward and a product is pushed forward at the front end of the work W, the clamp device 39 moves back and the front end of the work W is positioned at the rear side from a cutting line CL.  When the table 23 moves back to the original position, then, the front end of the work W does not come in contact with the sawtooth BS, so the damage to the sawtooth BS can be avoided.

Title: Zoom lens tracking adjusting device
Inventor: KOBAYASHI KIYOTAKA
IPC: G02B7/10
Filed: 1990-10-20
Abstract: PURPOSE:To eliminate need for rotating a rear group lens in relation to a light axis and to certainty prevent light axis deviation of a zoom lens as caused by such rotating adjustment by adjusting the initial position of a cam face with a cam member rotated in relation to a movable cylinder in the end section of a variable power area. CONSTITUTION:Tracking adjustment for a zoom lens is sperformed with a cam member 27 rotated corresponding to the movement of an adjusting plate 29 by shifting a movable cylinder 16 to a wider end. The cam member 27 is rotated by the rotation of this adjusting plate 29 and the rotation of the cam member 27 is smoothly performed with a cylindrical section 27c sliding on the inner periphery of a plate 28 for preventing the cylindrical section 27c from coming out. Since the rear group driving frame 25 and a rear group lens frame 13 are advanced and retreated in the direction of a light axis corresponding to the displacement of a cam face 27a due to the rotation of the cam member 27, the tracking of the rear group lens can be adjusted. After the adjustment, when the screws loosened are fastened again, the cam member 27 is fixed to the movable cylinder 16, the tracking adjustment for the rear group lens is completed. This constitution prevents the light axis of the zoom lens from deviating and eliminates light axis adjusting required.

Title: Input circuit
Inventor: SHINODA MASANOBU
IPC: H04B10/07
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To provide an input circuit robust against noise by amplifying a signal after noise elimination not to saturate an amplifier by the noise even if the noise approximating a DC is superposed on the signal and is inputted. SOLUTION: The signal current on which the noise current generated by a light reception element 1 is superposed is shunt by base grounded transistors TRs 11 and 12. The signal from the collector of the TR 12 and the signal from the collector of the TR 11 are inputted to a differential amplification circuit 50 in the next stage and are amplified. When the frequency of the inputted noise is low, the noise is not amplified because of being inputted to the differential amplification circuit 50 as an in-phase signal, and only the signal is amplified.

Title: Coder and its method
Inventor: NAKAYAMA TADAYOSHI
IPC: H04N19/91
Filed: 1998-10-06
Abstract: PROBLEM TO BE SOLVED: To simply apply variable length coding to a multi-value image at high speed by comparing results of accumulating data corresponding to parameters in the unit of plural multi-value image data so as to decide an optimum parameter. SOLUTION: Bit shifters 501a, 501b, 501c... shift a received quantization value to right by one bit. Furthermore, accumulators 502a, 502b, 502c,... 502z store initial values 2N-(a+2)N and accumulate N sets of values received sequentially. The accumulators store respective ID information and provide an output of it together with the accumulation of N-sets of values to post-stages. Furthermore, comparators 503a, 503b, 503c compare the accumulated sums from the two accumulators and gives the value which is smaller and the ID information to the post-stages, The comparator 503z at the final stage gives an output of the ID information to a Golomb coder 106. The ID information is the same as a k-parameter and the variable length coder 106 receiving the ID information quickly confirms the k-parameter based on the ID information.

Abstract: PURPOSE:To contrive higher safety and maintainability, by inhibiting an automatic hot water pouring operation when a failure of a system component or a sign of possible abnormal condition which would hinder continuation of the operation is detected, and displaying on a remote control unit the inhibited item and the cause thereof. CONSTITUTION:When a button 8 for pouring hot water into a bathtub is depressed on a main remote control unit 3 under the condition where hot water supply is inhibited (disabled), hot water supply is inhibited automatically, and a buzzer is operated three times, while hot water fill-up LEDs 9, 9a and a hot water pouring/fill-up arrow LED 12 rapidly blink three times. On the other hand, when a button 8a for pouring hot water into the bathtub is depressed on a bath-room remote control unit 4 under the same condition, a hot water pouring LED 10a rapidly blinks three times. When the cause of the inhibition (disabling) is the detection of hot water shortage (insufficient residual amount of hot water) in an automatic hot water supplying part, one of residual hot water amount monitor LEDs 13 (the one beneath the figure 50) on the main remote control unit 3 blinks rapidly three times. Besides, on a bath-room remote control unit 4, a hot water fill-up LED 9a blinks. When the hot water in the bathtub is at or above a predetermined temperature, a temperature display at a seven-segment LED 14 blinks rapidly three times.
