Title: Dial pulse detecting circuit
Inventor: MORIIDE HIROYUKI
IPC: H04Q1/32
Filed: 1982-09-21
Abstract: PURPOSE:To prevent the increase in the make rate of a dial pulse due to line capacity, by inserting a resistance having a capacitor in parallel via a diode to a line and comparing the difference between the voltage drop of the resistance and the capacitor. CONSTITUTION:The resistance R is inserted to a line transmitting a dial pulse and the capacitor C is connected in parallel with the resistance R via the diode D. A voltage comparator COMP having a hysteresis characteristic is connected between the resistance R and the capacitor C. A potential difference across the resistance R and the capacitor C is respectively zero at an initial state and the output of the comparator COMP is at a low level. In closing a contact (a), the potential difference of the inputs A, B of the comparator COMP is a forward voltage drop VF of the diode D and it exceeds a threshold voltage VT, the output goes to a high level. When the contact (a) is opened, the voltage drop of the resistance R is decreased, and when the potential difference of the inputs A, B exceeds a negative threshold voltage, the output of the comparator COMP goes to a low level.

Abstract: PURPOSE:To prevent the collapse of an LDD structure by forming an N<-> layer of a source region by phosphorus diffusion from a side-wall PSG and forming an N<+> layer of a source and drain region by the subsequent ion implantation. CONSTITUTION:On a P type silicon wafer 11, an SiO2 film 12 for gate, a refractory metal thin film 13, and an Si3N4 film 14 are formed in order and nextly a gate region is patterned by etching. Subsequently a side-wall PSG film 15 of the gate region is formed.

In this case, a thin N<-> layer 17 is formed on a surface of the wafer 11. Next, after N<+> impurities are implanted, the desired N<-> layer 18 is formed on the wafer 11 right under the film 15 and an N<+> layer 19 is formed in the N<+> ion implantation region. Then the film 14 is removed to obtain a MOSFET.

Filed: 1995-06-30
Abstract: PURPOSE: To provide a heating/cooking apparatus wherein oil flowing out from an article to be cooked is prevented from sticking to a bottom surface of the article to wet the article with oil when an oil adjusted food is reheated. CONSTITUTION: A food placement surface 15 of a dish 14 on which an article 18 to be cooked is placed is made uneven. The placement surface is inclined and the dish 14 includes an oil reservoir 17.

IPC: H01L21/28
Filed: 1985-07-29
Abstract: PURPOSE:To construct a timer circuit with a decreased number of elements, by implanting movable ions in a gate oxide film of an MOS transistor so that the threshold voltage can be changed depending upon the magnitude of a gate voltage applied to the gate electrode or upon the cumulative time of application of the gate voltage. CONSTITUTION:When a predetermined positive voltage is applied to a gate electrode 5, a channel 8 is formed between N-type diffused layers 2 and 3 in a P-type silicon substrate 11 and a source electrode 6 and a drain electrode 7 are electrically connected to each other. Movable ions 10... within a gate oxide film 4 are translated to the channel 8 in accordance with the voltage applied to the gate electrode 5. An electric field is retained to some degree even if the voltage application to the gate electrode 5 is stopped. If the predetermined positive voltage is continuously applied to the gate electrode 5, the threshold voltage is progressively decreased with the progress of time from the initial value V0 by the translation of the movable ions 10..., such that the extent of decrease of the threshold voltage corresponds to the cummulative time of application of the gate voltage. By utilizing the variation of the threshold voltage, the transistor can be employed as a timer.

Title: Clamp circuit
Inventor: MIWA MAKOTO
IPC: H04N5/18
Filed: 1983-09-07
Abstract: PURPOSE:To reduce temperature drift of an output by providing an analog switch feeding back a signal output of a differential buffer circuit via a sample- and-hold circuit and other analog switch intermitting the signal output. CONSTITUTION:When the analog switches 8, 9 are turned off by a sample pulse, a reference voltage Vref1 and a signal input are applied to an input terminal of a differential buffer circuit 6 and the output of the circuit 6 at that time becomes the voltage Vref1 by the adjustment of the circuit. When the switch 8 is turned on through the absence of a sample pulse, since a value held to the sample-and-hold circuit 7 is applied to the input terminal of the circuit 6, the output is made constant independently of the change in the average value of the signal input by the in-phase signal component suppressing effect of the circuit 6. Since a reference voltage Vref2 is outputted when the switch 9 is turned off by the sample pulse, the continuity of the output is kept by adjusting the voltage Vref2.
