Filed: 1989-04-27
Abstract: PURPOSE:To prevent the retention of a still picture signal under an incomplete recording state by automatically reproducing the still picture signal recorded lastly immediately after the recording of the still picture signal and displaying the normal/defective condition of the recording state obtained by a deciding means. CONSTITUTION:A deciding means 16 decides the normal/defective condition of the recording state of a storage unit based on a reproduced signal from the storage unit. A control means for controlling the operation of this deciding means 16 automatically reproduces the still picture signal recorded lastly out of consecutive still picture signals stored in a storing means immediately after the still picture signal is recorded and makes the deciding means 16 decide the normal/defective condition of the recording state especially at consecutive photographing. A display means 17 visually or aurally displays the normal/ defective condition of the recording state at this time obtained by the deciding means 16. Thus, it can be prevented that the still picture signal under the incomplete recording state is retained.

Title: Apparatus for detecting liquid amount in container
Inventor: ICHIKAWA OSAMU
IPC: G01S15/08
Filed: 1986-05-09
Abstract: PURPOSE:To obtain the title apparatus capable of detecting a liquid amount accurately even if a liquid level is inclined and the liquid amount is small, by calculating the distance between a transmitter-receiver and the liquid level in a container by detecting the resonance frequency of a sonic wave and calculating the liquid amount from said distance. CONSTITUTION:An inlet pipe 12 is connected to the upper part of the side surface of a container 10 and an outlet pipe 14 is connected to the lower part thereof. When a liquid 16 is supplied to the other part through the outlet pipe 14 and the liquid in the container 10 is reduced, the liquid 16 is supplied from the inlet pipe 12. Herein, the distance between the front surface of a transmitter-receiver 18 and the liquid surface 22 of the liquid 16 is set to (l). A sonic wave of which the frequency varies is transmitted from a transmitter 20 and the sonic wave reflected by the liquid surface is received by a receiver 24. The variation of said frequency is slowly performed so that the frequency of a transmitting wave becomes almost equal to that of a receiving wave. When the sonic wave resonates in the space 12 between the transmitter- receiver 18 and the liquid surface 22, n-order resonance frequency f(n) is calculated according to a predetermined formula when the value of (n) is known. If the difference between f(n) and f(n-k) is detected, the distance (l) can be calculated according to a separate formula.

Title: Integrated circuit with d/a converter,converter from digitalto analogue and its method
Inventor: SUTEIIBUN JIYOSEFU DAUBAATO
IPC: H03M1/10
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To perform D/A conversion on multiple bits at a high speed by biasing a calibration circuit with a first reference voltage and each array cell of the most significant bits and least significant bits with a second reference voltage. SOLUTION: The 64th MSB cell in an MSB array replaces a cell which is being calibrated. In an MSB cell 200, data selection switches S1 , S2 and S3 , S4 are respectively in opened and closed states and a whole output current I0 is forcibly made to flow through the calibration switch S3 , and then, a current source IS supplies most (0.95I0 ) of the output current I0 and a calibration transistor M1 supplies the remaining part (0.05I0 ) of the output current I0 . The same calibration circuit 150 which calibrates each MSP cell corrects the mismatching between the calibration transistor M1 and current source IS. In additon, the voltage at a node 3 is maintained at the same value between the calibration mode and an operating mode and the errors of cell currents caused by the fluctuation of the VDS of the calibration transistor M1 and the variation of the current source IS are reduced.  Therefore, the calibrating time becomes shorter and a high operating speed is obtained.

Title: Fm receiver
Inventor: KAWAKAMI KENICHI
IPC: H04B1/10
Filed: 1992-04-27
Abstract: PURPOSE:To reduce the distortion of a modulation signal at the time of monaural reception when multi-pass distortion is generated by providing a high frequency interruptio filter for passing only the low frequnecy signal of the modulation signals and a selective circuit for selecting and outputting either one of the modulation signal and the low frequency signal. CONSTITUTION:An FM detected modulation signal F is inputted to one of a signal selecting circuit 4, passes through a high frequnecy interruption filter 3 and a modulated signal LF of the low frequency components is inputted to the other side of the circuit 4. Also, an AC voltage signal V goes to an AM component detecting signal VD through an AM component detecting circuit 6 and controls the circuit 4. The circuit 4 is switched so as to select and output the signal F when no multi-pass distortion is present and to select the signal LF for which the signal VD is increased and reaches a set value when the multi-pass distortion is generated. Then, the filter 3 appropriately sets interruption characteristics in order to suppress high frequency distortion components due to the multi-pass strain at the time of the interruption frequency and monaural reception. Thus, as the distortion part of the signal F, the multi-pass distortion at the time of the monaural reception can be substantially improved.
