Patent JP-S60194571-A (JP)
Title: Manufacture of semiconductor device
Inventor: YAMADA MASAHIRO
IPC: H01L21/28
Filed: 1984-03-16
Abstract: PURPOSE:To form side walls at a low cost and with good reproducibility by a method wherein a diffused layer of self-alignment using the thick side of the side surface of a gate electrode as a mask is formed by ion implantation, and the stepwise difference is flattened with the film. CONSTITUTION:A gate film 202 and a gate electrode 203 are formed on an Si substrate 201, and SOG is spin-coated. After coat of a film 500Angstrom  to 1,000Angstrom  thick at the flattened section at the time of spin coating, nitrogen annealing was carried out at 800 deg.C. This reduces the film thickness by about 40%. Utilizing an SOG characteristic of becoming thick at the stepwise difference, a side wall 204 is formed and P<+> or As<+> ions are implanted by ion implantation, thus forming an LDD layer 205. Besides, a CVD film was formed on the SOG film remaining after ion implantation, resulting in the formation of an insulation film. Thereby, the stepwise difference can be flattened at the same time, and is further flattened more conveniently and with better reproducibility than conventional.

Title: Flow meter
Inventor: TAKEHARA KATSUNAO
IPC: G01F1/22
Filed: 1983-03-26
Abstract: PURPOSE:To generate a warning of variation in flow rate exceeding a permissible value by detecting a pointer, etc., which deflects according to a flow rate without contacting and deciding the time of flow rate variation from a specific flow rate, and deciding on whether the time of flow rate variation is larger than the permissible value or not. CONSTITUTION:The position of the pointer or float 5 which shifts in position according to the flow rate of a flow meter 1 is detected by a photocoupler 8 consisting of a projector and a photodetector and the flow rate is adjusted to a specific value. A measuring circuit 9 for the time of variation in flow rate decides on the time of variation in flow rate on the basis of the detection output of the photocoupler 8, and its decision value is compared by a comparator 11 with the permissible value of the flow rate variation time set by a timer 10 to decide on whether the time of flow rate variation exceeds the permissible value or not. When so, an alarm device 12 is operated by the decision signal of the comparator 11. Thus, a warning of variation in flow rate exceeding the permissible value is generated to prevent a defective from being formed unknowingly.

Title: Semiconductor analog switch
Inventor: UENO MASAHIRO
IPC: H03K17/16
Filed: 1982-03-31
Abstract: PURPOSE:To obtain a semiconductor analog switch which has reduced dependance on the input voltage with small error voltage, by using two switching field effect transistors (TR) having equal conductive channels and connected in parallel and a compensating field effect transistor having the same conductive type as the switching field effect transistors with the source and the drain short- circuited to each other. CONSTITUTION:When an analog switch is turned off, i.e. gates G1 and G2 are set at 0 and 1 respectively, the channels of the 1st and the 2nd TRs QMN2 and QMN2 disappear. Instead a channel is formed under the gate of the 3rd TR QCN1 for compensation whose gate is connected to the 2nd gate terminal which is driven with the polarity opposite to the 1st gate terminal. As the current is set at 0 at a moment when the analog switch is turned off, the carriers within the TRs QMN1 and QMN2 are discharged by 1/2 toward the source and drain sides respectively and then absorbed almost completely by the channel of the TR QCN1 and not delivered to the outside of the switch.

Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To generate low energy neutrinos with a simple and low cost device so as to be detected, and to perform a neutrino communication by making use of them and to observe the solar neutrinos. SOLUTION: Three stages of layers in each of which a sheet of thin paper moistened with a salt solution is sandwiched between a wide copper plate and a wide aluminum plate are stacked so as to form a Voltaic pile (a first Voltaic pile). A weak magnetic field which is parallel to its surface is applied by using a solenoid coil which is wound around it. Then, another Voltaic pile (a second Voltaic pile) to which no magnetic field is applied is formed in the same manner as the first Voltaic pile. The first Voltaic pile and the second Voltaic pile face each other, and a distance between both faces is increased. Thereby, when the first Voltaic pile is discharged, neutrinos are generated. The generation of an increment in the electric discharge of the second Voltaic pile is read out by a galvanometer.

Filed: 1984-03-17
Abstract: PURPOSE:To stabilize the operation by connecting a two-way constant voltage element between a gate and a main electrode so as to reduce the effect due to temperature fluctuation in a two-way semiconductor switch circuit using a triac. CONSTITUTION:When an AC voltage is impressed between main electrodes T1 and T2 of the triac 1 connected with a varistor 6 being the two-way constant voltage element between the gate G2 and the main electrode T2, most of the voltage is impressed across the varistor 6, and when the peak value exceeds the varistor voltage, a current flows to the varistor 6 so as to turn on the triac 1. The impedance of the triac 1 and the varistor 6 at turn-off is very high, the effect due to the impedance change of other circuit elements is not susceptible, and even when a pulse generator is constituted by connecting a nonlinear inductive element 5 and an inductor 4, the effect of the impedance temperature characteristic of the element 5 is decreased so as to activate the circuit stably.

Title: Calculating method for gps radio wave reception position
Inventor: KOJIMOTO KENICHI
IPC: G01C21/00
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To precisely calculate a reception position with a simple structure by receiving radio waves from a plurality of GPS artificial satellites, determining the distances from the artificial satellites based on propagation times, and calculating the position where differences between distances and differences between propagation times are offset. SOLUTION: The coordinate value of a reception position is assumed, the information obtained from a plurality of GPS artificial satellites 1-4... is collated, the reception position is moved to reduce errors, and the coordinates of the reception position can be calculated with the prescribed precision. Calculation can be simplified because the reception position is assumed without being calculated based on other information. The prescribed precision can be set in relation to the moving distance of the reception position. The calculation precision of the reception position can be improved when the number of the GPS artificial satellites 1-4... sending radio waves is increased, however the reception feasible number is limited in relation to orbits 1a-4a.... For three- dimensional position detection by utilizing GPS, radio waves must be received from four artificial satellites.

IPC: H04H20/00
Filed: 1987-03-06
Abstract: PURPOSE:To synchronize the broadcast of a slave station with the signal of a master station by allowing a broadcast equipment to input the synchronizing signal of a phase synchronizing circuit and to send a master station signal synchronizing with the synchronizing signal, thereby allowing a slave station to receive directly the synchronizing signal sent from the master station with a simple constitution. CONSTITUTION:An amplitude compensation section 10 compensates the amplitude of a distributed output 14a so as to be of the same level as the signal level of a reception signal 3a received by a reception antenna 3. Moreover, a 180 deg. phase compensation section 11 adjusts a phase difference between the distributed output 14a and the reception signal 3a to 180 deg.. In receiving a reception signal 3a and a feedback signal 11a, a synthesizing circuit section 4 eliminates the carrier component of both signals and extracts only the synchronizing signal superimposed on the master station signal 4a, that is, the broadcast signal and gives the result as an output. Furthermore, a distribution section 6 distributes the master station signal 4A into two directions, one distributed output is outputted to a middle wave broadcast equipment 12 and the other distributed output is outputted to a filter section 5, which passes through the synchronizing signal component from the master station signal and gives it to a phase comparator section 7.

Inventor: KUSUSE YOSHIHISA
IPC: H02H3/00
Filed: 1985-03-14
Abstract: PURPOSE:To easily detect the shortcircuit place of a power source line, by cyclically increasing and decreasing the resistance value of a variable resistor connected to the power source line to generate a flicker current and detecting the presence of the flicker current by a clamp meter. CONSTITUTION:One line L1 of power source lines L1, L2 is detached from a breaker 2 and variable resistors R1, R2 are connected during this time. The resistor R2 is set so as to flow a predetermined current matched with the characteristics of a clamp meter to the lines L1, L2. The movable contact piece 1 of the resistor R1 is driven to flow an AC current shown by an arrow to the lines L1, L2. At this time, a flicker current rather flows to the side of the breaker 2 than a shortcircuit place 3 but does not flow to the terminal side from the shortcircuit place 3. Therefore, by successively detecting the flicker current flowing from the side of the breaker 2 to the lines L1, L2 by the clamp meter, the shortcircuit place 3 can be easily detected.

Filed: 1985-03-15
Abstract: PURPOSE:To prevent damages even when plural keys of the same stage are mis-operated without providing any diode, by constituting a scanning circuit of a selection circuit and tri-state circuit. CONSTITUTION:When the key B of a key matrix 1 is operated, a key row 11 is firstly designated from a designating section 41 and a selection circuit 62 makes a tri-state circuit 631 only high in potential in a scanning circuit 60. At this time, signal lines 31-34 stay low in potential. Then another key row 12 is designated form the designating section 41 and a tri-state circuit 632 only is similarly made high in potential. As a result, the the signal line 31 becomes high in potential and it is discriminated that the key B is operated. When keys A and B are simultaneously mis-operated, the high potential supplied to the key row 11 is transmitted to a signal line 22, but, since the tri-state circuit 632 is under a cut-off condition, the scanning circuit 60 is not damaged.
