Title: Control device for submergible pump
Inventor: HARA MASAHIKO
IPC: F04D13/08
Filed: 1994-11-17
Abstract: PURPOSE: To make a compensation for a drop in a discharge water volume due to a drop in water level and ensure a constant water volume to be discharged by raising a motor speed at every constant time after the start of the motor. CONSTITUTION: This device is formed out of a microcomputer, the control circuit thereof and a submergible pump. The microcomputer takes in the readings of an external switch as well as encoder pulses from the motor, thereby computing a projection speed. Thereafter, the microcomputer makes a comparison among instruction speeds and controls the duty of PWM signals. The control circuit is formed out of a PWM control circuit, a signal distribution circuit and an overcurrent detection circuit. AC voltage applied from the outside via a power cable is rectified and converted to high DC voltage and low DC voltage for driving the microcomputer.  According to this construction, the motor is driven according to the timing when a float switch for high and low level detection is turned on, and a motor speed is raised at a constant ratio, so as to maintain a discharge water volume at an initial speed. Sewage water is thereby discharged, even when a water level drops.

Title: Sun and frost cover
Inventor: SASAKI YOSHIAKI
IPC: B60J11/00
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To block direct sunlight and prevent frost on glass, by mounting a winding retractable sheet which can be pulled out from a storage case to the outside of the front or rear automotive windshields. SOLUTION: A winding type sheet 1 is provided at the outside of the front or rear automotive windshields, such that it is pulled out from a storage case 3 and attached to the windshield. When parking for extended periods in summer, the direct sunlight coming through the front windshield rapidly raises the temperature inside the vehicle. Also, in winter the glass frosts, requiring significant effort to remove the frost. In comparison, if the sheet 1 is pulled out from the winding-type storage case 3 to cover both front or rear windshields, direct light is blocked and the formation of frost is prevented. Use of this structure where the sheet 1 is retractable and the retracted sheet 1 is stored in the attached storage case 3 facilitates storage of the sheet 1 in the case 3 attached to the vehicle.

Title: Recording disk reproducing device
Inventor: OKADA TAKEHIRO
IPC: G11B17/041
Filed: 1985-12-17
Abstract: PURPOSE:To surely detect information of a cover in a disk player of automatic loading type, by providing a mediate member abutting with an uneven part that transmits recorded information of the disk in a holding mechanism and abutting the mediate member against a detection switch of the player. CONSTITUTION:Simultaneously with a disk holding mechanism 90 becomes 'cover disk holding state', an abutting pin 291 that became in contact with the convex part of a notched part for discriminating information provided on the cover 3 slides in the direction of rear face of the disk holding mechanism 90 and projects from a fixed wall by a fixed quantity. When 'cover holding state' is passed and the disk holding mechanism 90 is shifted in the direction X2, the projected abutting pin 291 comes into abutting against corresponding cover detection switch 295 and judges that it is the convex part. Thus, as the information detecting mechanism of the cover 3 is divided into a holding means and a detecting section, drawing of lead wires is eliminated, and the main body can be made thin as it is provided in the direction of shifting.

Title: Video signal reproducing device
Inventor: OGURA HIDEFUMI
IPC: H04N5/85
Filed: 1993-10-18
Abstract: PURPOSE:To satisfactorily link images betweel frames by displaying plural frames at a certain frame interval larger than the number of those frames. CONSTITUTION:When the time for reading video data required for displaying N frames from a video disk 1 is equal to the time for displaying them, data read and display are thus executed. When this operation is completed, the device is turned to the state of reading the next data by driving a slide motor 5 or displacing an optical head 3. This access time is set shorter than a vertical blanking period. When the compressed data are recorded in the disk 1, the read time is shorter than the display time but at such a time, the rotating speed of the disk is set low. When the disk 1 recorded with the compressed data is reproduced, the read time is made shorter than the display time. At such a time, an access period from the end of reading to the next reading is made longer than the vertical blanking period, and it is possible to deal with the high-speed reproduction of a CLV disk as well without using any frame memory.

Title: Balanced voltage- current converter
Inventor: ADORIANUSU SENPERU
IPC: H03F3/45
Filed: 1988-11-11
Abstract: PURPOSE: To increase a linear range (dynamic range) by adding or subtracting an input signal flowing to bases of 1st and 2nd transistors(TRs) to/from collector currents of the 1st and 2nd TRs through 1st and 2nd differential pairs respectively. CONSTITUTION: A signal current flowing to a collector wire of a TR T7 equal to a base current of a TR T5 is subtracted from an emitter current of a TR T5 . An input impedance of a voltage-DC converter between input terminals 19, 20 is remarkably small due to negative feedback surrounding TRs T5 , T6 and distortion caused by a change in the circuit input impedance is reduced. Moreover, since a logarithmic base-emitter voltage of the TRs T5 , T6 is provided by TRs T8 , T9 with a high voltage gain respectively, the TRs T5 , T6 are almost completely turned on. Thus, the dynamic range of a mixer circuit is increased.

Title: Expandable antenna reflection mirror
Inventor: TAJIMA TAKANORI
IPC: H01Q1/27
Filed: 1994-11-18
Abstract: PURPOSE:To obtain an expandable antenna reflection mirror for space being surely expandable without generating entanglement in a cable network for holding a mirror surface in orbit. CONSTITUTION:Only an expansion rib 4 is expanded in the initial stage of expansion and a cable 2 is kept fixed to a center hub 3 and can not freely move. As the expansion advances, the cable 2 is pulled by the expansion rib 4 and tensile force is applied to a first housing cable 6. When the tensile force is applied to the housing cable 6, a planar spring 8 is bent, the housing cable 6 is released and a part of the cable is released, however, since the tensile force is already added to the cable 2, a movable range is extremely less and the entanglement is hardly generated. By repeating the operation and successively releasing the housing cables 6 to which the tensile force is applied, since the free movement of the cable is suppressed to a minimum during the entire extension, the entanglement is reduced.
