Abstract: PROBLEM TO BE SOLVED: To detect a timing signal on next reception even when failing in receiving the timing signal in a clock with a time correction function for intermittently receiving the timing signal and correcting based on the timing signal. SOLUTION: A reception result of a previous on-the-hour signal is reflected by a variable that is a RIREKI being provided at a RAM in a control circuit 22, and the control circuit 22 determines a next power supply time width to a FM radio reception unit 1 according to the value. In the case of RIREKE = 0, the power supply time width to the FM radio reception unit 1 is set to 2 minutes (AM 7 o'clock ± 1 minute). In the case of RIREKI = 1, it is set to 30 seconds (AM 7 o'clock ± 15 seconds), and in the case of RIREKI = 2, it is set to 10 seconds (AM 7 o'clock ± 5 seconds). When the on-the-hour- signal is successfully received, a digit 1 is added to the RIREKI. On the other hand, when the reception fails, the digit 1 is subtracted from the RIREKI. The control circuit 22 controls the power supply time width to the FM radio reception unit 1 according to the value.

Title: Light wavelength converting device
Inventor: SHINOZAKI KEISUKE
IPC: G02F1/35
Filed: 1989-12-07
Abstract: PURPOSE:To improve the efficiency of conversion from a fundamental wave to a higher harmonic by making the projection direction of the 2nd higher harmonic different from the projection direction the fundamental wave. CONSTITUTION:The fundamental wave is made incident on a 1st surface 37a from one reflecting surface 35a of an optical resonator at a Brewster angle and projected on the other reflecting surface 39 of the optical resonator from a 2nd surface 37b at a Brewster angle. Consequently, the fundamental wave is confined to the path of the one reflecting surface 35a, the 1st surface 37a, the inside of nonlinear optical crystal, the 2nd surface 37b, and the other reflecting surface 39. The 2nd higher harmonic generated in the nonlinear optical crystal is polarized at right angles to the fundamental wave, so the wave is reflected by the 2nd surface 37b. Consequently, the projection direction of the fundamental wave is different from the projection direction of the 2nd higher harmonic. Consequently, the efficiency of the conversion from the fundamental wave to the 2nd higher harmonic is improved.
