Patent JP-H03190157-A (JP)
Title: Semiconductor device
Inventor: YAMAZAKI TAKASHI
IPC: H01L27/04
Filed: 1989-12-19
Abstract: PURPOSE:To enhance a semiconductor device in electrostatic breakdown strength and to improve it in reliability by a method wherein a well whose conductivity type is opposite to that of a substrate is formed on the surface of the substrate just under a gate, and the potential of the well is set equal to that of a power supply. CONSTITUTION:An insulating film 3 is formed on a P-type silicon substrate 1, and a gate 4 is formed on the insulating film 3 between P<+>-type diffusion layers 5 and 5. The potential of an N well 2 is set equal to a supply potential Vcc out of a power supply potential, which serves as a reference potential at an electrostatic breakdown test. Therefore, when a high voltage is applied onto a semiconductor device for an electrostatic breakdown test, and even if the high voltage occurs in the substrate 1, the well 2 is kept constant at a certain potential free from the influence of the high voltage, and thus a MISFET capacity is protected against the influence of the high voltage con cerned by the well 2. That is, a transient current is prevented from flowing through a circuit, so that the gate insulating film 3 or the junction area of semiconductors different in conductivity type can be protected against break down.

Title: Dry burning preventing device
Inventor: HAYASHI TAKEHIKO
IPC: F24H1/18
Filed: 1990-11-30
Abstract: PURPOSE:To prevent the occurrence of dry burning by a method wherein a first thermostat is mounted on the flange in the vicinity of a topmost electric heater and a second thermostat on a tank on a horizontal plane in the vicinity of a horizontal position in the vicinity of the topmost position of the electric heater. CONSTITUTION:A first thermostat 7 is mounted on a heater flange surface 6. A second thermostat 8 is mounted on a tank on a horizontal plane in the vicinity of the topmost part of an electric heater. A water feed tank is filled with water through a water feed port 9 and an electric heater 5 is turned ON. In the case of a tank being filled with water, the temperature of the first thermostat 7 is kept at the same level as that of the temperature of the second thermostat 8. When an electric heater 5 is turned ON in a state that water is not fed in the tank, the temperature of the first thermostat 7 mounted on the heater flange 6 of the electric heater 5 is increased, and a difference between the first thermostat 7 and the second thermostat 8 mounted on the tank is increased. When a temperature difference exceeds a set value, operation of an electric water warmer is stopped, and the electric heater 5 is protected. For example, when a water level in the tank is (a), a temperature difference between the first and second thermostats 7 and 8 is increased along with the increase of a water temperature between (a)-(b) and the electric heater is stopped through dry burning prevent function.

Title: Pre-charge circuit
Inventor: TANOI SATOSHI
IPC: G11C11/34
Filed: 1987-12-28
Abstract: PURPOSE:To execute the pre-charge of a half level at a high speed by connecting the drain edge of a pair of FETs, which are serially connected, to distributed capacity together with the gate of the FET in a source edge side and obtaining a circuit constant, with which the source side FET goes to be non-saturated in the initial period of a pre-charge start. CONSTITUTION:For FETs 11 and 12, a gain coefficient beta and a threshold voltage VT are at a same degree. Then, in the initial period, a potential of a terminal B is VB=0 and the FET11 is turned off. Then, the FET12 is turned on and a potential of a terminal A is VA=VDD. When a control signal phi is changed to 0V, the FET11 is turned on and a charging is started to capacity 13. When the gain coefficient and threshold voltage of the FET are obtained at the same degree, in the initial period of the charging, a power source voltage VDD is pressure-divided and the FET12 goes to a non-saturated condition. Then, since a VDS12 goes to be smaller, a VGS11 of the FET11 can be increased more than a conventional circuit and a high speed charging can be executed with a large charging current. Then, the VB rises up and in the condition of VDD-VT, VGS12= VT is obtained. Then, the FET12 is turned off and the charging is ended.

Abstract: PURPOSE:To eliminate the need for earthing by arranging a contact between a communication line and a subscriber's equipment, arranging a control signal discrimination circuit and a contact drive circuit between 2 wires being a communication line and providing a state storage function to at least either or the contact or the contact drive circuit. CONSTITUTION:When a control signal with an opposite polarity is applied between communication lines 101, 102, that is, when a voltage of -100V is applied to the line 101 with respect to the line 102 of the communication line, a current flows to a control signal discrimination circuit 105, but the current flows a polar contact drive circuit 111 in opposite direction, that is, flows from the communication line 102 toward the control signal discrimination circuit 105 and since the contact drive circuit is a polar circuit, the contact 113 is closed in the opposite position. As a result, the communication lines 101, 102 are disconnected from a termination circuit 114 and connected to indoor lines 103, 104, resulting in restoring the original state finally. Then the state storage function is provided to the polar contact drive circuit 105 or the contact 113, then the state of the contact is kept even after the control signal is lost. Thus, no earthing is required.

Filed: 1987-12-26
Abstract: PURPOSE:To completely erase a pre-recording signal and to improve the picture quality of a consecutive recording part by arranging an erase head, whose width is wider than the width of a track pitch, so that the pre-recording signal of the consecutive recording part can be erased. CONSTITUTION:In a revolving drum 1, an erase head 10, whose width is wider than that of the track pitch, is arranged so that the pre-recording signal of the consecutive recording part can be erased. A track to be recorded with an SP mode by magnetic heads 2 and 3 is recorded in a 48mum width. On the other hand, since the track-pitch width of a magnetic tape 4 is 58mum, the track by the heads 2 and 3 goes to be dispersed in 58mum. However, at a consecutive recording time, since the erase head, whose width is wider than the track-pitch width 58mum, is preceding, the pre-recording signal can be erased without fail and the satisfactory picture quality of a high S/N can be formed in the consecutive recording part.
