Title: Light source unit
Inventor: UENISHI NAOTA
IPC: G02B6/32
Filed: 1988-05-14
Abstract: PURPOSE:To converge light into a small spot by collimating secondary higher harmonic waves which are projected by an optical fiber type secondary higher harmonic generating element and have an axially symmetrical and a conic equiphase plane by a collimator lens which has a slanting symmetrical surface at least partially. CONSTITUTION:This unit is equipped with a laser light source 1, the optical fiber type secondary higher harmonic generating element 4 which generates a secondary higher harmonic from laser light emitted by the laser light source 1, and the collimator lens 5 which has the slanting circularly symmetrical surface at least partially and converts the secondary higher harmonic wave projected by the secondary higher harmonic generating element 4 into a parallel light beam. Namely, the secondary higher harmonic spreads as a conic beam B by passing through the clad 42 of an optical fiber 4, so the secondary harmonic is passed through the collimator lens 5 which has the slanting circularly symmetrical surface partially to obtain the parallel light beam of the secondary higher harmonic. Then this beam is converged by a converging means. Consequently, the small spot which nearly coincides with the limit of light wavelength is obtained.

Title: Coring circuit
Inventor: CHIGIRA HIROKAZU
IPC: H03G11/00
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To generate the output signal only for an input signal having a high level without generating an output signal for the input signal having a low level by comparing the level of an output terminal voltage with that of a second reference voltage and supplying an output current corresponding to the difference to an output terminal. SOLUTION: When the output current of a signal current source 1 is in the no-signal state of 0, the voltage of an output terminal 4 becomes a DC voltage Vref of a first reference voltage source 3. Consequently, the voltage Vref is applied to the base of a transistor TR 8 of a comparator, and the comparator 5 enters the balanced state, and collector currents of TRs 7 and 9 are made equal, and there is not a current from a point A to a resistor 6 or a reverse current, and the comparator 5 doesn't have an influence upon the voltage of the output terminal 4.  When the output current of the signal current source 1 has a high level, the voltage of the output terminal 4 is generated in the direction and the quantity of the supply input current and the comparator 5 is immediately operated, but its influence is ignored if the current value of an operation current source 1-of the comparator 5 is made sufficiently smaller than the output current of the signal current source 1.

Subsequently, after the raw soln. is perfectly transferred to the mixer 2, a valve 20 is opened and the mixed soln. is transferred to the mold 2 by pressure difference and, after the injection into the mold 2 is completed, a reduced pressure state is kept for a definite time and the reduced pressure in the box 8 is released and nitrogen gas is introduced to restore atmospheric pressure.  Thereafter, a flat plate-shaped molded object is taken out of the mold 2.

Title: Paper folding device
Inventor: TAKEUCHI TAKASHI
IPC: B65H45/14
Filed: 1983-06-30
Abstract: PURPOSE:To make a paper folding slip preventable, by setting nip pressure between first and second rollers so strong as a degree capable of making paper to be inserted into space between second and third rollers after both ends in and around the feed direction side of the paper. CONSTITUTION:In a state that nip pressure between first and second rollers 11 and 12 produced by a spring 21 is set at a pressure point P1 and being skewed, even when paper 17 is fed to the side of a chute 14 and one end of a feed direction side face 17a reaches to a bottom part of the chute 14, this nip pressure P1 is not so large to the extent of partially bending the paper 17 so that the paper 17 is no longer inserted into space between second and third rollers 12 and 13. During a while, the other end of the side face 17a reaches to the bottom part of the chute 14 whereby a skew in the paper 17 is corrected. At this time, both ends of the side face 17a of the paper 17 are detected by sensors 15 and 15, and since the nip pressure between these first and second rollers 11 and 12 is set to a pressure point P2, the paper 17 is largely bent in a partial manner and therefore inserted into space between these second and third rollers 12 and 13, thus the paper is correctly folded up.

Title: P-n-p-type bipolar transistor
Inventor: FURUKAWA AKIO
IPC: H01L29/73
Filed: 1989-05-15
Abstract: PURPOSE:To avoid the deterioration of the controllability of a bipolar transistor due to a depletion of a base layer and a reduction in a current gain and to obtain the transistor having good characteristics by a method wherein the amount of an N-type dopant, which is located in the sides of an emitter layer and a collector layer to the base layer or in the side of the collector layer, in the base layer is doped higher than that in the center of the base layer. CONSTITUTION:For example, a P-N-P-type bipolar transistor consists of an emitter layer 1, a base layer 2, a collector layer 3, a low-concentration base layer 4 and a high-concentration base layer 5. In this case, by providing the layer 5 in the sides of the layers 1 and 3 to the layer 2 or by providing the layer 5 in the side of the layer 3, a depletion of the layer 2 ts avoided. An effect to a current gain and the time when holes pass through the base layer, which is caused by providing the layer 5, is not so great because the thickness of the layer 5 is thin. Thereby, the depletion of the layer 2 is avoided without deteriorating characteristics, such as the current gain and the time when the holes pass through the base layer 2, and the transistor can be controlled.
