Title: Error signal detector of optical head
Inventor: MUSHIYA TOORU
IPC: G11B7/09
Filed: 1983-05-11
Abstract: PURPOSE:To suppress the displacement of an object lens and the generation of DC offset and to enhance the detection sensitivity by dividing the light receiving face of a photodetector into three or more in the tangential direction with respect to a track and performing an operation processing on the basis of signals in the light receiving area distant from the optical axis and the light receiving area close to the optical axis. CONSTITUTION:Outputs of individual elements 31a-31f of a 6-divided optical detector 31 are denoted as (a)-(f), respectively. The first focus error signal (FE signal) (a+b+e)-(c+d+f) is obtained by sum circuits 32 and 33 and a difference circuit 34, and outputs (e) and (f) are used to obtain the second FE signal by a circuit 35. The first FE signal has a wide dynamic range but has a low detection sensitivity. The second FE signal is obtained with the quantity of light in the peripheral part of the photodetector 31. Since the variation of the quantity of light in the peripheral part is very high for the deviation of an optical disc from the in-focus position, the detection sensitivity of the second FE signal is very high. Consequently, focus servo with a wide dynamic range and a high precision is possible by both signals. Meanwhile, a radial error signal (a+b)-(b+d) is obtained by sum circuits 36 and 37 and a difference circuit 38.

Title: Wafer id recognition method
Inventor: NAKAJIMA KEN
IPC: G01N21/88
Filed: 1988-04-01
Abstract: PURPOSE:To prevent the lowering of a wafer ID recognition rate by removing a resist applied on the wafer ID using a resist developer, an organic solvent, on a peeling liquid before recognizing a wafer ID (recognition number). CONSTITUTION:Before irradiating light in advance on a wafer ID (recognition number) 11 using a light source 21 of a halogen lamp or the like, a wafer ID part 11 alone of a resist 13 applied on the wafer ID upper part is removed followed by irradiating light 22 on the wafer ID part 11. Accordingly, even when the light 22 is irradiated using any light source 21, the resist 13 actually exposing a desired pattern becomes insensitive. Thereby, the recognition rate lowering due to the incoming of the resist 13 on the step of the wafer ID (recognition number) part 11 presents no problem.

Title: High frequency heating device
Inventor: WASHIMI YUJI
IPC: H05B11/00
Filed: 1988-04-01
Abstract: PURPOSE:To eliminate use of any rush current preventing resistance which has been required in a conventional arrangement by using a heater for the heater heating mode as a preventive resistance for the rush current generated in the early period of power feed to a high frequency heating device, and by using a relay having a make/break contact for the purpose of changing over this circuit. CONSTITUTION:Before current is supplied to a high tension transformer 1, a heater 5 used for the heater heating mode is connected in series to the trans former 1, and after current feeding, circuit connection is changed over by the use of a relay 10 having a make/break contact in order to connect the trans former 1 with the heater 5 in series. After this high tension transformer 1 is once energized, another relay 9 shortcircuits the ends of the heater 5. When the contact of the relay 10 is to be opened and closed, it shall be done so that no arc will be generated between contacts. This permits elimination of a rush current preventive resistance which has been required in a conventional arrange ment.

Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To realize an encoding device from which a still picture with high picture quality can be obtained. SOLUTION: A frame memory 2 of this encoding device receives a digitally converted video signal. A picture discrimination information output means 3 provides outputs of information denoting complexity in the unit of macro blocks of a still picture with high resolution stored in the frame memory 2 to a quantization width control means 6 and of address information of a macro block to a memory control means 4.

Title: Level meter circuit
Inventor: YOSHIDA TOMOAKI
IPC: G01R19/165
Filed: 1980-06-19
Abstract: PURPOSE:To display the current value and maximum value of input signal levels with simple circuits by changing over the AD conversion value at the current point of time and the maximum value having been stored and held and controlling the operation of a read-on-memory. CONSTITUTION:When a changeover signal input terminal 119 is set at L, the AD conversion outputs 1-3 of input signal levels are inputted to a decoder 43, and only one of output terminals 51-58 is selectively set at H. At this time, a read-only- memory circuit 59a operates normally, and the current value is displayed in a bar graph by 8 pieces of LEDs connected to the output terminals 111-118. Next, when the input terminal 119 is set at H, the signal code of the maximum value having been stored in a storage circuit 5 is outputted from a signal selecting circuit 4. Since the memory circuit 59a is inhibited of operation, the output of the decoder 43 is transmitted as it is to the output terminals 111-118, and only the one point corresponding to the maximum value is displayed. Thereby, the current value is displayed by a bar graph and the maximum value is displayed in combination as well.

Title: Semiconductor device and its manufacture
Inventor: KOGA HIROTAKA
IPC: H01L29/72
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of the switching characteristic of a MOS transistor by forming oxide film spacers on the sidewalls of a nitride film aperture and making the width of the nitride film aperture wider than the width of a trench prior to the formation of the MOS transistor. SOLUTION: A silicon oxide film 7 is formed over the inner wall of a trench 6, and a silicon oxide film 8 is formed so that the trench 6 is completely buried. Then, a silicon nitride film 3 is selectively removed. The inside of the trench 6 is filled with the films 7 and 8, and silicon oxide film spacers 5 and the film 8 project from the surface of a silicon substrate 1. Since the film 8 protrudes over a device region by z1 from the width of the trench 6 on each side, it does not occur that only the film 7 is etched quickly, and thus no hollow is formed on top of the trench 6. Therefore, the switching characteristic of a MOS transistor to be formed thereafter is prevented from deteriorating.
