Title: Optical parametric oscillating device
Inventor: SUZUKI HIDEO
IPC: H01S3/10
Filed: 1991-02-12
Abstract: PURPOSE:To reduce Fresnel loss without varying the projecting position of output light and permit a wide wavelength variable range. CONSTITUTION:Excitation light from excitation light sources 20 and 22 excites a pair of nonlinear optical crystals 31 and 32. Two beams of light (signal light and idler light) generated by the nonlinear optical crystals are resonated in a closed-loop optical path formed by resonating mirrors M1, M2, M3 and M4. Therefore, the generated light is a wave proceeding in one direction and not easily disturbed. Rotating devices 24a and 24 are used for varying the resonance conditions of the generating light, and the pair of nonlinear optical crystals 31 and 32 are rotated in synchronism in the opposite direction to the optical path. Thus, optical path deviation caused by the one nonlinear optical crystal can be compensated by the other crystal. The projection position of the output light outputted in response to the resonance conditions is not influenced by the wavelength variation.

Title: Data reproducing device
Inventor: NAGATA YUKINOBU
IPC: G11B20/14
Filed: 1986-01-31
Abstract: PURPOSE:To correctly decode the contents of each bit data by following the timing of a read gate signal to a clock pulse and appropriately correcting it if the hourly interval of the clock pulse fluctuates within a permissible range. CONSTITUTION:The side of a control circuit 6 waits that the read gate signal rises to 'H'. After the rise is detected, the side repeatedly checks the binarization output of a binarization circuit 5 as long as 'H' continues. When the rise is detected, a detection flag is set. If the read gate signal is detected to fall from 'H' to 'L', the state of the flag is checked. Here a read gate signal generator circuit 8 transmits the hourly interval of the clock pulses before and after a counter 802 to a comparator 803. If the hourly interval of the clock pulse is decided to fluctuate within the permissible range, the timing of the read gate signal is appropriately corrected by following the clock pulse.

Abstract: PURPOSE:To hold a tool in a stable manner against a supporting plate even in case the tool is of a shape producing an unbalanced load by providing a tool adapter with a ball plunger, which can freely be engaged with or disengaged from a supporting-plate positioning hole. CONSTITUTION:A groove part 8 of a tool adapter 4 can quickly be engaged with a supporting plate 6b, because a brim part 7a of a tool supporting port becomes thinner toward the opening part side. The tool adapter 4 embraces the brim part 7a of the tool supporting port, with both inner side surfaces of upper and lower collar parts 4a, 4b facing both right and wrong surfaces of the supporting plate 6b. With this, a tool 5 is prevented from coming off from the tool supporting port in the right-and-wrong direction of the supporting plate 66. At the same time, the tool 5 can be held in a stable manner against the supporting plate 6b, even in case the tool 5 is of a shape producing an unbalanced load. In addition, since the ball plunger 10 of the tool adapter 4 is engaged with a positioning hole of the supporting plate 6b, the tool 5 can surely be positioned.
