Abstract: PURPOSE:To resolve the occurrence of the reluctant box packing that the large end sections of lengthy objects are overlapped by changing the direction of the lengthy objects in turn, and shifting them when the tapered lengthy objects such as carrots are conveyed by a conveyor one by one and dropped into a box for box packing. CONSTITUTION:Lengthy objects 3 on a shift belt 1 are shifted along the preset shift axis A by a guide mechanism 2, and a direction judging sensor 5 detects whether the small end section 3a of the lengthy object 3 or the large end section 3b precedes. An electric controller 8 judges whether the direction of the lengthy object 3 is to be inverted or not after detecting which section precedes to change the direction of the lengthy objects 3 in turn. If the direction is not to be changed, an inverting rotor 6 is rotated to an arrow R1 by a power source 7, and the lengthy object 3 is shifted in the shift direction B in slide contact with its slide receiving face 6b. If the direction is to be changed, the lengthy object 3 collides with a shock sensor 6e, the inverting rotor 6 is rotated to an arrow R2 by its output, the lengthy object 3 is inverted by its rotating force and the shifting force of the shifting belt 1, and the lengthy object 3 is shifted in slide contact with the slide receiving face 6b.

Title: Semiconductor laser driving circuit
Inventor: SATO HIDEAKI
IPC: H04B10/2507
Filed: 1989-09-08
Abstract: PURPOSE:To suppress the effect of a parasitic element so as to prevent the distortion of the waveform of optical output by applying a digital input signal to a semiconductor laser through a coupled capacity with low impedance. CONSTITUTION:A digital signal inputted into an input terminal 16 is inputted into one input end of an OR gate 18. Since the other input end of the OR gate 18 is fixed to a logical 'L' level VL, digital signals in the same wave form as input are output from output ends 22 and 23. But, the polarity of the output signal of the output end 22 is inverted. For the signal of the output end 22, only the AC components are applied to a semiconductor laser 19 through couple capacity C. Hereat, the output impedance of the output end 22 of the OR gate 18 is approximately equal to the impedance of the semiconductor laser 19, and is set to low impedance, so the occurrences of parasitic inductance to a high-speed digital signal and the wave form distortion by parasitic capacitance can be prevented.

Title: Driving device for stepping motor
Inventor: SETODANI NOBORU
IPC: H02P8/22
Filed: 1999-07-13
Abstract: PROBLEM TO BE SOLVED: To obtain a driving device which enhances the high-speed rotation characteristic of a stepping motor by a method wherein one phase out of windings with N-phases is provided with an exciting sequence which can apply a power-supply voltage. SOLUTION: For example, in a five-phase stepping motor, an exciting sequence is given to an output part wherein five motor windings which are connected annularly and five sets of switching element groups are provided. Consequently, a current is made to flow to three or four windings out of the five motor windings. That is to say, when clock pulses are inputted, the exciting sequence is shifted by one pulse portion. Then, a phase which is excited is shifted to four phases → three phases → four phases → three phases. Then, when the number of the exciting sequence is an odd number, a current is made to flow to the three windings out of the five motor windings, and a state that a power-supply voltage can be applied to one winding out of the three windings is set. As a result, the frequency of the clock pulses is raised, and ths stepping motor is turned at high speed.  When the current of the steeping motor is reduced, its reduction amount is reduced, and the high-speed rotation characteristic of the stepping motor can be enhanced.

Abstract: PURPOSE:To obtain large output, improve high frequency characteristics, and restrain the irregularity of element characteristics, by arranging an operating layer having a specific gradient wherein concentration gradually increases from a surface, just under a gate electrode or in the vicinity of it, and making source.drain region except this a high concentration layer which is not deeper than the operating layer. CONSTITUTION:On a GaAs semiinsulative substrate 1, an N-type high concentration operating layer 2 in the range of 3-10X10<17>cm<-3> is formed to have a desired threshold voltage. Then an N-type low concentration operating layer 3 in the range of 1-7X10<16>cm<-3> in the vicinity of the surface is grown in thickness ranging from 200 to 2000Angstrom , and an epitaxial layer having a specific step-wise concentration distribution is formed. A high melting refractory metal, e.g., WSix is stuck, and a gate electrode 5 of shot junction is formed. An N-type high concentration region 4 is formed, which is deeper than the layer 3 and shallower than the layer 2, and the concentration is higher than the layer 3. While the step-wise concentration distribution of the layers 2, 3 is almost kept, the layer 4 can be formed in a self-alignment manner, and then low resistance metal 6 can be selectively formed in a body. Therefore, parasitic resistance reduction and gate junction capacitance reduction can be simultaneously attained.
