Patent JP-S5915204-A (JP)
Title: Laser unit
Inventor: NAKAOKA MASAKI
IPC: H01S5/00
Filed: 1982-07-17
Abstract: PURPOSE:To put a light emitting point into depth of a focus of a lens, irrespective of a variation of an ambient temperature, by giving a difference of thermal expansion to a lens barrel supporting member and a lens barrel member. CONSTITUTION:A lens supporting member 4 made of iron (coefficient of thermal expansion: beta1) is fixed to a substrate 9 after laser light is made to conform with an optical axis of a lens 2. A lens barrel 1 of a collimator lens is made of aluminum having a coefficient of thermal expansion (beta2) of about three times of iron, and is fixed to the lens supporting member 4 after focusing at a distance of l1 from the substrate 9. Also, a distance l2 between a fixing point A of the lens barrel to the supporting member, and the lens is about l1Xbeta1/beta2-l1/3. According to such a constitution, when an ambient temperature is varied by + or -t deg.C from the time of focusing, the lens supporting member 4 extends by +(+ or -t deg.C)Xl1Xbeta1 in the direction (y), but on the contrary, as for the lens 2 of the collimator, its lens barrel extends by -(+ or -t deg.C)Xl2Xbeta2=-(+ or -t deg.C) Xl1Xbeta1 in the laser tip direc tion. In this way, a working distance DELTAl by a temperature variation is not varied. In this regard, a distance l3 is thickness of a laser tip fitting member, and this fitting member is subjected to a temperature control, therefore, is not influenced by an environmental temperature variation.

Title: Automatic medium oblique travel correction device
Inventor: KAJITANI HIROSHI
IPC: B65H5/06
Filed: 1986-05-30
Abstract: PURPOSE:To automatically correct an oblique travel of a paper sheet regardless of its thickness, by simultaneously regulating an interval of one of rollers and an interval of one of guide plates in front of the rollers in a device for correcting an oblique travel of the paper sheet by a convex-shaped roller for gripping a paper sheet at a point and for feeding it and a stopping plate. CONSTITUTION:A fixed guides 24, 18 and a movable guide 20 are disposed between a convex-shaped drive roller 16 and a pressure roller 17 for feeding a paper sheet from a direction A. The roller 17 moves together with the movable guide 20. When the paper sheet 27 comes to the position of the rollers 16, 17, a magnet 25 is deenergized so that the force of a spring 22 causes the rollers 16, 17 to clamp the paper sheet 27. At the same time, the roller 16 rotates so that the paper sheet 27 is fed by the rollers 16, 21 and its oblique travel is corrected by the stopping surface of a stopper 23. The roller 16 projects a little from a guide 24 and the roller 17 from a guide a little so that the guide 20 and the roller 12 move vertically in accordance with the thickness of the paper sheet 27. With the arrangement, buckling is prevented regardless of a paper shect, whereby an oblique travel can be automatically prevented.

CONSTITUTION:By pushing the channel selection buttons 6, 7 of feather touch, the channel selection operation is performed. Resides, as for the output value of a counter 8 for generating a tuning voltage, the value below a certain value is allocated to the VHF low band, and the value above that value is allocated to the high band, and at the same time, the switching of a tuner 2 of the VHF low band/high band is automatically performed by the output of a circuit 10, which decides whether the said output value is larger or smaller than the set value. In addition, the non-adjusting of the setting of the tuning voltage range for every band can be realized because the output of the D/A converter 9 is amplified and level-shifted by an operational amplifier. Besides, because the generation of the tuning voltage and the switching of the band are executed electrically, a stable operation can be ensured for a long period.

Title: Pll circuit
Inventor: EBATA KAZUYOSHI
IPC: G11B20/14
Filed: 1986-05-30
Abstract: PURPOSE:To perform a fast searching action with a PLL circuit by providing a pull-in means at the output side of an LPF to compare the output of the LPF with a prescribed voltage level an feeding the error signal of comparison back to the LPF. CONSTITUTION:The pull-in voltage Vp is produced from a pull-in voltage generating circuit 21 by the pull-in voltage control signal received from a pull-in voltage control circuit 22. Then the voltage Vp is compared with the output of an LPF 8, i.e., the VCO control voltage Vc. When the Vc is higher than the Vp, an error current, for example, is applied to the capacitor of the LPF 8 from a pull-in circuit 20. Thus the output voltage level of the LPF 8 is reduced. While an error current, i. e., the discharging current received from the capacitor of the LPF 8 is applied to the circuit 20 when the Vc is lower than the Vp. Thus the output voltage level of the LPF 8 is raised up. Thus it is possible to stabilize the pull-in action, to short the pull-in time and the perform a searching action at an ultra-high speed.

Abstract: PURPOSE:To perform presetting with one operation, by storing a reception frequency automatically, at the moment when the state is transferred from a nonturning state to a tuning state. CONSTITUTION:When any boadcast signal is received by operating an automatic channel selecting switch 6' and automatically sweeping a reception frequency, an output of a channel selection stop instruction detecting circuit 22 is changed from a low level to a high level and the reception frequency is fixed.
