Title: Radio receiver
Inventor: IMAI KAZUO
IPC: H04H40/72
Filed: 1995-07-06
Abstract: PROBLEM TO BE SOLVED: To reduce the noise of a high frequency component by providing the hysteresis characteristic with respect to a received electric field level to a control circuit receiving the received electric field level and controlling an electronic attenuator. SOLUTION: A detection demodulation circuit 3 detects an electric field level to discriminate whether or not the electric field level is higher than a prescribed level such as 40dB(μV), and to discriminate whether or not the electric field level is lower than a prescribed level such as 30dB(μV) when the electric field level is lower than the 40dB(μV). When whether or not the electric field level is lower than the 30dB(μV), a control circuit 7 provides the output of an H level to a base of a transistor (TR) 11 thereby decreasing a treble control voltage. When the electric field level is more than the 30dB(μV) and less than the 40dB(μV), the hysteresis characteristic is provided to the control circuit 7 to keep the existing operation so long as the electric field strength is fluctuated between the range above.  When the treble control voltage applied to an electronic attenuator 4 is increased, the boost level of a high boost circuit 4b in the inside of an IC is increased and when the applied voltage is decreased, the boost level is decreased.

Abstract: PURPOSE:To aim at the improvement of the travelling stability by leading a throttle pressure and a throttle modulator pressure opposite to a governor pressure into a shift valve under the down shift condition, and leading only the throttle pressure under the up shift condition. CONSTITUTION:When a 2-3 shift valve 17 is under the second gear speed condi tion, a spring 17a, the throttle pressure PT and the throttle modulator pressure PTM press a spool 17b is right direction, and a governor pressure PG presses the spool 17b in left direction opposite to it. On the other hand, under the third speed condition, the input ports 17g, 17h of the throttle modulator pressure PTM are closed so that the spring 17a and the throttle pressure PT press the spool 17b in right direction opposite to the governor pressure PG so that the hysteresis is given at the time of the down shift and the up shift. The hysteresis in the range of the low throttle opening degree thus enlarges large and the improvement of the travelling stability can be aimed.

Title: Electronic balance
Inventor: SATO TAKESHI
IPC: G01G23/01
Filed: 1992-06-30
Abstract: PURPOSE:To calibrate the sensitivity of a balance in compliance with a user's purpose by detecting whether the output change of a load sensor generated when the sensitivity is calibrated, satisfies the set permissible range of the change. CONSTITUTION:A load sensor 2 in an electronic balance housing 1 measures the weight of an object 4, and is also capable of measuring the weight by placing the weight of a weight 5 housed in the housing 1 onto a load receiving part 3. The output of the sensor 2 is sent to a data processing part 20 every predetermined minute time interval. The processing part 20 not only averages the load data, but operates a calibration coefficient from the output data at the calibrating time and so on. On the other hand, simultaneously with the calculation of the sensitivity calibration coefficient, it is detected whether the changing width of a group of output data of the sensor 2 at the calibrating time of the sensitivity is within a set permissible range of the change width. If the change width is within the permissible range, the calibration program is terminated. However, if the change width exceeds the permissible range, a warning buzzer 13 is sounded and the fact is displayed at a display panel 11.

Title: Controlling apparatus of printing density
Inventor: ARAI SEISUKE
IPC: B41J2/36
Filed: 1991-07-12
Abstract: PURPOSE:To speed up printing by a method whereby the history and the state of printing are evaluated, an output of an output driver is adjusted according to the evaluating result thereby to raise the temperature of an output part to the vicinity of the printable temperature, and printing is conducted with the shortest pulse width at the same applying voltage. CONSTITUTION:The noteworthy printing content or history (printing after blank lines are continued in a series of the printing operation) stored in a printing buffer 4 is evaluated by an evaluating part 3. The data of the output pulse width and the output timing is fed to an output driver 1 from an output adjusting part 2 in accordance with the evaluating result. The output driver 1 outputs a printing adjusting pulse based on the data before printing is conducted. This pulse has a short width set so as not to raise the temperature of the head to the printing temperature, but raises the temperature close to the printing temperature. The evaluating part 3 counts the number of lines not printed for every divided unit of the lines, and sends tone result to the output adjusting part 2. The output adjusting part 2 determines the size of the printing adjusting pulse based on the input data.

Abstract: PURPOSE:To improve the switching function by enhancing the junction areas of a base and a graft base by utilizing a difference in diffusion speed of Zn between two materials, InP and InGaAsP when using these as crystal materials. CONSTITUTION:The crystal plane is covered with SiO2, Si3N4 or the like selectively and an InP layer 102, an InGaAsP 103, and an InP layer 104 are etched to reach a semiconductor substrate 101 by use of an etchant of chlorine or bromine group. After a cleaning process, crystal growth is made in the etched part selectively to form a semiconductor layer 105. In this case, for example, Zn is used for a P type impurity of the semiconductor layer 105 and the concentration of carriers is determined higher than in the semiconductor layers 102, 103, and 104. Consequently, Zn is autodoped into the semiconductor layers 102, 103 and 104 by heating at crystal growth of the semiconductor layer 105. At this time, the diffusion speed of Zn is extremely slower in InGaAsP than in InP so that the autodoped diffusion front becomes as designated by a dotted line in the figure.

Title: Electric charge detecting circuit
Inventor: ITOU YUUICHIROU
IPC: H03F3/45
Filed: 1979-12-27
Abstract: PURPOSE: To prevent a connection between the output terminals of the CS amplifiers of two systems, by using the electric charge sensing amplifiers (CS amplifiers)  of three systems, the electric charge holding capacitor, the inverting capacitor and  the switching circuit.  
     CONSTITUTION: The electric charge input is applied to the input terminals of the 1st and 2nd CS amplifiers 1 and 2, and the output voltages V 1  and V 2  are caused at the output terminals. Under such conditions, the change-over switches SWa∼SWc are switched to the terminals 32, 42 and 53. As a result, the capacitors K 1  and K 2  are charged to the voltages V 1  and V 2 . Thereafter, the change-over switch is  switched to apply the voltage of the capacitor K 1  to the 3rd CS amplifier 7. On the other hand, the terminal connected to the switch SWb is earthed in the capacitor K 2  with the other terminal detached from the earth. Thus the voltage of the terminal connected to the switch SWc becomes -V 2  to be applied to the amplifier 7. As a result, the output voltage proportional to V 1 -V 2  can be obtained.

Filed: 1988-07-11
Abstract: PURPOSE:To excellently form an electrically insulated thin film on a base plate by charging positive potential in a grid against a filament and impressing AC potential to an electrode for holding the base plate in a vacuum vessel. CONSTITUTION:DC power sources 22, 21 are connected with a filament 7 and a grid 6 in a vacuum vessel and the grid 6 is charged with positive potential against the filament 7. Further AC power sources 23, 20 are connected with a counter electrode 5 and an evaporation source 8. In this constitution, active gas and/or inert gas are introduced into the vacuum vessel and evaporation substance held in the evaporation source 8 is evaporated. The particles of the evaporation substance are flown toward a base plate 100 and ionized into positive ions by the thermions of the filament 7 and passed through the grid 6 and a thin film is formed on the base plate 100. At this time, when the thin film is electrically insulated, the surface of this thin film is made a state charged to positive by the positive ions but this positive charge is destaticized by the electrons which are accelerated following the positive ions and reach the base plate side. Thereby excess charge is prevented from being built-up on the thin film and the excellent insulating thin film is formed.
