Patent JP-H07226629-A (JP)
Title: High frequency mixer circuit
Inventor: OTA MUTSUTO
IPC: H03D7/12
Filed: 1994-02-10
Abstract: PURPOSE:To lower a voltage and to reduce power consumption by adding the first high frequency signal of a frequency f1 to the base of a first transistor TR, adding the second high frequency signal of the frequency f2 to the base of a second TR and taking out frequency conversion signals from the collector of the second TR. CONSTITUTION:When the high frequency signal of the frequency f1 is inputted through a capacitor C1 to the base of the TR1, the TR1 amplifies the high frequency signal of the frequency f1 and outputs it from the collector and the high frequency signal of the frequency f1 is impressed to the emitter of the TR2. In the meantime, since the local oscillation signal of the frequency f2 is inputted through the capacitor C. to the base of the TR2, the signal of the frequency (f1+ or -f2,) the signal of the frequency f1 and the signal of the frequency f2, etc., appear on the side of the collector by the nonlinear operation of the TR2. Only the signal of the frequency (f1+ or -f2)=f3 is taken out through the capacitor C3. Since the high frequency signal and the local oscillation signal are respectively added to the bases of the different TRs, separation of the signals are sufficient and supply to the corresponding TRs is efficiently performed. Also, since only one power source Vc2 or Vc1 is sufficient for a bias voltage supply part 2 and a high frequency mixer part 3, the power consumption is reduced.

Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To switch a reproduction mode better by automatically judging a recording mode of a tape status recording medium mixed with recorded parts based by a plurality of recording modes. SOLUTION: A CTL pulse PCTL is reproduced by a magnetic head 26 from a magnetic tape 15 to be supplied to servo circuit 25. A magnetic tape 15 is mixed with recorded parts by an analog recording mode and a digital recording mode and the recording interval of the CTL pulse PCTL varies with the individual recording modes. A speed detection circuit 28 calculates a running speed Vabs of the magnetic tape 15 using information on the winding diameter (r) on the winding side and angular velocity and the information is supplied to the servo circuit 25. As the ratio of the running speed Vabs to the number per specified time of the pulses PCTL gives a value corresponding to the recording mode involved, the servo circuit 25 discriminates the recording mode of the recorded part presently reproduced based on the ratio to generate a switching control signal Csw.  Switches 29 and 37 are turned by the signal Csw to enter a reproduction mode corresponding to the recording mode.

Title: Crystal oscillator of temperature compensation type
Inventor: YOSHIDA HIROSHI
IPC: H03B5/32
Filed: 1990-01-26
Abstract: PURPOSE:To measure the temperature of a crystal vibrator accurately by connecting electrically and thermally one terminal of a temperature sensor and one terminal of a crystal resonator and using a level of a connecting point as a reference level. CONSTITUTION:One terminal of a crystal resonator 14 connects electrically in series with one terminal of a temperature sensor 15. Since a lead wire sharing a large ratio as each thermal conduction path is connected in series thermally, even when both the crystal resonator and th temperature sensor have a thermally large drop, heat is delivered through the lead wire and an equilibrium is quickly transited. This, a nearly equal temperature is kept quickly between both the crystal resonator 14 and the temperature sensor 15 quickly. Thus, the temperature sensor 15 measures the temperature of the crystal resonator 14 accurately and traces the change quickly thereby attaining accurate temperature compensation.

Title: Lamp driving device
Inventor: AZUMA AKIHIRO
IPC: G01R31/02
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To detect abnormality of a lamp in its off-period even when the lamp is controlled in an on-condition by detecting abnormality of the lamp by a lamp abnormality detecting means only at off-driving time of the lamp by a lamp driving means, and temporarily performing off driving on the lamp when the lamp driving means performs on-driving. SOLUTION: When an on/off condition of a lamp 1 is realized, an microcomputer 3 outputs a control signal H/L, and a driving element 2 is turned on and off, and the lamp 1 is lighted and put out by a power source (+) B. The microcomputer 3 can judge the existence of disconnection of the lamp 1 when the lamp 1 is controlled in a lights-out condition by whether detecting output of an A point is L or H, but cannot judge it when the lamp 1 is controlled in a lighting condition. Therefore, the microcomputer 3 imparts a control signal L to the driving element 2 only for a period (t1), of about short 120μs unknown to eyes of a person, and the lamp 1 is put out. Therefore, even when the lamp 1 is controlled in an on-condition, abnormality of disconnection of the lamp can be detected.
