Filed: 1991-03-29
Abstract: PURPOSE:To prevent a prescribed phase shift or above from being generated in the output clock of a 2nd PLL circuit. CONSTITUTION:A phase comparator 13 compares the phase of a clock B from a frequency divider 11 with the phase of a clock A from a 1st PLL circuit 100 and gives the result of comparison to low pass filters X, Y in a filter circuit 14. A phase shift detection circuit 12 detects a deviation in the phase between the clocks A and B and outputs a detection signal E in response to the deviation. A selector 15 outputs selectively either the output of the low pass filter X or the output of the low pass filter Y and inputs the selected output to a VCOX 10. When the deviation in the phase of the clocks A, B is larger than a prescribed value, the responsiveness in a 2nd PLL circuit 200 is quickened by selecting the low pass filter Y with a high interruption frequency, thereby allowing the clock B to follow quickly to the clock A.

Title: Lockup control device of automatic transmission
Inventor: OGURI KAZUO
IPC: F16H61/14
Filed: 1990-03-15
Abstract: PURPOSE:To accomplish the release of lockup at the starting stage securely by connecting a fail-safe passage to which the oil pressure is fed when the starting stage is accomplished and the oil pressure is cut off when a speed change stage is accomplished, to a passage at the lockup releasing side. CONSTITUTION:When the speed is shifted to the first speed of the starting stage by the 1-2 speed shift valve 71, the oil pressure fed from a main oil pressure circuit 100 through a regulator valve 61 flows from an input side oil pressure circuit 300A to an output side oil pressure circuit 300B, bypassing a lockup control valve 201 which is not operated by an disorder and feeding to a lockup clutch 26, and it releases the lockup clutch 26 from a lockup condition. And in a speed change stage in which the lockup clutch 26 is connected at the second speed or higher, the oil pressure is cut off to the fail-safe passage 300B by the 1-2 speed shaft valve 71. As a result, even though the gear is shifted from P or N range to D range in an idling condition, no engine stop is generated, and the fluid coupling effect of a torque converter 20 can be realized.

Title: Solid-state laser oscillator, solid-state laser medium, laser resonator, and laser exposure device
Inventor: TAKEHISA KIWAMU
IPC: H01S3/094
Filed: 1991-03-29
Abstract: PURPOSE:To enable an Nd:YAG laser to output laser rays of high power 946nm in wavelength. CONSTITUTION:Exciting rays 105a and 105b transmitted from semiconductor lasers through optical fibers 103a and 103b are made to irradiate a thin plate- like Nd:YAG laser medium 101 at an angle to an optical axis. By this setup, laser oscillation rays 108 having a wavelength of 946nm are generated. As a large number of exciting beams around an optical axis can be emitted, laser rays of high power can be outputted. Especially, as it is high in reabsorption property, a short laser medium must be used, and therefore it is adequate for a case where a semiconductor laser is required to be used when a lamp can not be used as an exciting light source.

Title: Pulse amplifier circuit
Inventor: NAGINO SHINJI
IPC: H03K5/02
Filed: 1978-06-05
Abstract: PURPOSE: To reduce the complicacy of the circuit and then to secure the pulse amplification with the stable operation point by connecting the input and the output of the NOT gate of C-MOS via the high resistance and thus forming an amplifier circuit the operation point of which is decided uniformly.  
     CONSTITUTION: The pulse voltage produced through detection of the optical pulse signals by the photo detector is supplied to inverter 26 via the differential circuit. The output of inverter 26 features an intermediate level by feedback resistance 27 when no signal exists. If the pulse is applied under these conditions, the input voltage is inversely amplified to emerge at the output side. When the output of inverter 26 features the negative voltage to the input, diode 28 connected in parallel to the feedback resistance is short-circuited. And thus inverter 26 loses the amplifying function. Inverter 26, like the normal gate, features the functions for the positive- negative inversion and the waveform shaping, thus obtaining the output waveform at terminal 33.
