Title: Microwave flow meter
Inventor: HARUO HIROSHI
IPC: G01F1/52
Filed: 1984-11-01
Abstract: PURPOSE:To measure a flow rate highly accurately even if a water surface is dropped by arranging a microwave absorbing member immediately under the water surface from which microwaves are radiated in a flow meter obtained by combining a microwave level gauge and a permaporous frume. CONSTITUTION:A microwave is radiated from an originating part 1a, reflected by the water surface, the reflected wave is inputted to a receiving part 1b and the water level is detected by a water level converter 5. The permaporous frume 2 is arranged on the bottom of a passage to stop water flow. The microwave absorbing material 6 is fitted to the leg part of the frume 2. When the water level is dropped, the microwave is reflected on the water surface and even if a part of the microwave is transmitted through the water, the transmitted wave is absorbed by the absorbing material 6 and is not received by the receiving part 1b. Since the microwave absorbing material is arranged immediately under the water surface from which the microwave is radiated, the flow rate can be detected highly accurately.

Title: Controller of electric opening and closing device
Inventor: HIRATA MASAMI
IPC: E06B9/68
Filed: 1990-08-30
Abstract: PURPOSE:To make it possible to understand accuratly present conditions even if an electric opening and closing device is not directly seen by displaying the present conditions of the electric opening and closing device on a display means of an operation section. CONSTITUTION:When a user pushes a vertical switch of an operation section 15, a micro-computer (CPU) 19 outputs a rising operation command signal SU during the period of duration, and the signal is transmitted to a CPU 11.

Title: Image forming device
Inventor: UOTANI SHUHEI
IPC: B41J29/00
Filed: 1985-10-14
Abstract: PURPOSE:To improve safety at the carriage of a device and the stability of a locking device at the time of use over a long period by arranging a locking device to be divided into upper and lower bodies on the opposite side to a hinge and forming a grip for carrying a body on the side of the locking device. CONSTITUTION:After locking an original platen 6, the grip 57 is grasped and rotated in the counterclockwise direction to carry the body by one hand under the state that the grip 57 is positioned on the upper side. Since the locking device 60 for the body is positioned on the opposite side to the hinge 2, i.e. on the opposite side to the grip 57, excess load is not applied to the locking device 60, an inexpensive device can be sufficiently adopted for the locking device, and even if the locking device is used over a long period, no backlash is generated. Since the opening side is turned downward at the time of carrying, no opening force is applied to the locking device and the locking device is not unlocked. Even if the device is unlocked, the device is not opened and safety can be maintained. Consequently, the important problem for the quality of the image forming device can be resolved and safety can be maintained without opening the device even at the time of carrying.

Thus, the absolute value of negative resistance is held larger than the effective resistance of a crystal vibrator even when a load capacitance is reduced in accordance with the control voltage and the oscillation is prevented from stopping.

Title: Complementary type semiconductor device
Inventor: ASAI SOTOHISA
IPC: H01L27/092
Filed: 1984-10-30
Abstract: PURPOSE:To reduce junction leakage currents by displacing a burying oxide film from a junction surface between a P well and an N well and forming it. CONSTITUTION:A burying oxide film 10 is shaped on the N well 2 side from P-N junction surfaces formed by a P well 2 and both an N well 2 and an N type substrate 1. A fact that the current amplification factor of a lateral bipolar transistor is reduced and a feedback is difficult to be applied is adapted by limiting the diffusion of carriers in the lateral direction by the burying oxide film 10. An effect at a time when a groove for burying the oxide film 10 is shaped can further be inhibited, thus reducing junction leakage currents, then minimizing power consumption.

IPC: G05F1/56
Filed: 1986-09-29
Abstract: PURPOSE:To attain the formation of high efficiency while utilizing high stability and low noise characteristic by forming a 1st control circuit for dropping the output of a 1st rectifier circuit when the output is higher than a regulated output, and at the time of generating an output lower than the regulated value, forming a 2nd control circuit for compensating a lacking amount from a 2nd rectifier circuit. CONSTITUTION:When an error signal is turned to a value higher than that of a 1st series transistor 1, a 2nd series transistor 2 is driven by utilizing the forward voltage/current characteristics of a diode and only the lacking amount is supplied to a load 7. At that time, the regulated output voltage V0 is set up to a value slightly lower than an output voltage V1 of the 1st rectifier smoothing circuit and the 1st series transistor 1 is always held at an operating state under a fixed output state to reduce a loss. When the output voltage V1 of the 1st rectifier smoothing circuit is dropped caused by the sudden change of a load current or change of an input voltage, a lacking component is supplied from the output voltage V2 of the 2nd rectifier smoothing circuit under control by the 2nd series transistor 2 to stabilize the power supply.

Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To improve the operability by using operation buttons in common while the minimum number of window switching buttons is provided even when the number of operation windows is increased and selecting a menu pattern being an operation object automatically when no operation is imposed for a prescribed time. SOLUTION: A selection means 5 selects a display information signal 33b as a 2nd selection signal output 5c based on a menu selection signal 5a selected by a menu selection button and does not select a 2nd selection output signal 5b. A deflection means 8 applies deflection processing to the selected signal to provide an output of a synthesis video signal 8b, then the operation content is displayed on a menu 2. In the case of operation of a menu 1, a common menu selection button is switched and similarly the menu 1 is displayed. When no operation of remote control is made for a prescribed time, the menu 1 is restored for selection automatically, the signal 33b superimposed on the video signal of the menu 2 is lost and undesired image display is automatically lost and the menu 1 is an operation object for a succeeding remote control operation.  Thus, 2-split screen indication offering ease of use is attained.
