Title: Controller for pickup output level of recording information reader
Inventor: AIZAWA HIROKI
IPC: H03G3/20
Filed: 1982-06-01
Abstract: PURPOSE:To prevent the output of error information despite an increment of the output level of photoelectric conversion, by detecting the DC component contained in the output of a signal converted by an electric signal converting part of a pickup and then controlling the AC component level of the converted signal in response to the DC level. CONSTITUTION:The output of a 4-split photodetector 1 is delivered through load resistances RL1-RL4 to be used as the inputs of corresponding LPFs2-5. Then the DC component is extracted by the LPFs2-5 to receive an addition process 6. The output of the adder 6 is compared with are ference level VR through a differential amplifier 7. The differential output of the amplifier 7 is applied to a control amplifier 9 via an LPF8. While anodes of diodes D1-D4 functioning as variable impedance elements are connected to each end of load resistances RL1-RL4, respectively. The cathodes of these diodes are connected in common and then grounded via a capacitor C1. Then the output of a control amplifier 9 is applied to the common joints of cathodes to control the both-end voltage of diodes D1-D4. Then the AC impedance is varied for each of those diodes.

Title: Picture signal processing unit
Inventor: SUZUKI TOSHIHIKO
IPC: H04N19/67
Filed: 1993-03-29
Abstract: PURPOSE:To prevent a high definition still picture from being discriminated in mistake as a moving picture. CONSTITUTION:An inter-frame difference is obtained from picture data passing through a low pass filter 2 at a frame delay device 3 and a subtractor 4 and an absolute value circuit 5 obtains an absolute value of the difference. An adder 6 and a delay device 7 obtain a sum of the absolute values and a discrimination circuit 8 compares the sum with a threshold value to discriminate the presence of a movement. Thus, the high frequency component of the picture data is attenuated, resulting that only information corresponding to the motion is obtained.

Title: Junction break-down type programmable read-only memory semiconductor device
Inventor: OONO NOBUHIKO
IPC: G11C17/14
Filed: 1978-08-02
Abstract: PURPOSE:To achieve writing in a short time by applying a collective current to a P<+> region formed in a part of an emitter-base junction. CONSTITUTION:When a writing pulse may be applied to the intermediate line between an emitter electrode E of a selected memory cell and a word line current absorption terminal C so that the junction face between an emitter region 17 and base region 14 is biased reversely, almost of the writing current is directed to a collector region 13 and N<+>-type buried layer 12 through a P<+>region adjacent to the emitter region 17. Therefore, the writing can be established by breaking down the P-N junction of the contact portion between the emitter region 17 and P<+> 15. In this case, because the area of the contact portion of the emitter region 17 with the P<+> region 15 can be reduced, the collection of the current is easily caused and a break-down is frequently occurred.

Title: Fluorescence measuring apparatus
Inventor: HAYASHI TSUTOMU
IPC: G01N21/64
Filed: 1991-03-29
Abstract: PURPOSE:To prevent an unwitting measurement of a sample having the inadequate concentration in the measurement of fluorescence. CONSTITUTION:Sample-transmitted light is measured with a photodetector 3. When the absorption of exciting light with the sample is higher than a preset levels, an alarming device 8 is automatically operated. When the concentration of the sample is too high, the relationship between the intensity of the fluorescence and the concentration does not become linear. Therefore, the measurement is usually performed after the sample is diluted. An operator who is not familiar with the fluorescence analysis tends to forget this step. The inadequate measurement is prevented by alarming the operator about the fact that the concentration of the sample is too high.

Abstract: PURPOSE:To prevent dielectric breakdown of a memory cell capacitor in the course of manufacturing, by forming an insulating film thinner than the insulating film of the memory cell capacitor, between the upper electrode of the memory cell capacitor and a semiconductor substrate. CONSTITUTION:An N-type well is formed on a P-type silicon substrate. At this time, a low concentration N-type diffusion layer 7 is simultaneously formed around a memory cell array; after LOCOS isolation, a high concentration N-type diffusion layer 2 is formed; a silicon surface is thermally oxidized, thereby forming silicon dioxide films 4, 8. The thickness of the silicon dioxide film 8 is 80Angstrom , but the thickness of the silicon dioxide film 4 is 100Angstrom , because impurity concentration of the diffusion layer 2 is so high that accelerated oxidation is caused. After that, by using a first polysilicon layer 3, the following are formed and a memory cell is completed; the upper electrode of a capacitor, a polysilicon gate layer 5, and a metal layer 6. In this manner, the silicon dioxide film 8 thinner than the silicon dioxide film 4 being the insulating film of a memory cell capacitor is formed, thereby preventing dielectric breakdown of the memory cell capacitor caused by storage of charged particle.
