Title: Recording mode discriminating device
Inventor: OTA HARUO
IPC: H04N9/79
Filed: 1989-06-26
Abstract: PURPOSE:To accurately discriminate a recording mode even when the amplitude of a reproduced FM signal is dropped by discriminating the recording mode based upon a signal proportional to the instantaneous frequency of the reproduced FM signal obtained by demodulating the reproduced FM signal. CONSTITUTION:An FM signal recorded with either one of two recording modes having different FM carrier frequency levels is reproduced from a magnetic tape and inputted to an input terminal 1 as a reproduced FM signal. The FM demodulating circuit 10 executes FM modulation, and outputs the signal proportional to the instantaneous frequency of the reproduced FM signal. Thereby, the DC level of an output signal from an FM demodulating circuit 10 is proportional to the carrier frequency of the reproduced FM signal. The FM- demodulated signal is inputted to a recording mode discriminating device 15 by DC connection so that its DC component is also transmitted and the DC component is extracted, so that the signal corresponding to the FM carrier frequency can be extracted and the recording mode can be discriminated. Thus, the recording mode can be accurately discriminated in accordance with the carrier frequency of the reproduced FM signal without depending upon the amplitude of the reproduced FM signal.

Title: Inverter device
Inventor: YOSHIDA HIROAKI
IPC: H05B41/24
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To provide a highly efficient inverter device that generates less noise without requiring no auxiliary booster means for a piezoelectric transformer. SOLUTION: Switching elements Q1 , Q2 are driven by control signals S1 , S2 from a control circuit 50, and conduct switching of direct current from an inputting terminal 10 to which DC voltage Vin is applied to generate the driving voltage of a piezoelectric transformer T1 . A choke coil L1 and the capacitor C1 at the primary side of the piezoelectric transformer T1 constitutes an LC series resonant circuit, whose resonant frequency drives the piezoelectric transformer T1 . Therefore, the driving voltage of the piezoelectric transformer T1 becomes a sinewave shape. An R1 , which is a resistor for detecting tube current iL flowing through a cold-cathode tube 40, controls the switching frequency of the switching elements Q1 , Q2 by applying negative feedback to the control circuit 50.  It is thus possible to change the driving voltage of the piezoelectric transformer T1 , and control power to be outputted according to it.

The layer (A) is removed and the resist layer is developed, and a pattern is formed. In this process, it is preferred that a water-soluble aromatic diazonium salt (e.g. compds. expressed by the formula) and a water-soluble high molecular compd. [e.g., poly(N-vinyl pyrrolidone)] are used for the layer (A). In the formula, each R1-R4 is H, alkyl, etc.; X is Cl, BF4, etc.
