Title: Method for boring through hole in electronic circuit board
Inventor: YOSHIOKA SHINYA
IPC: H05K3/00
Filed: 1985-11-15
Abstract: PURPOSE:To bore through holes of fine quality, i.e. without crack, chipping, or any other failure, with good yield by previously providing a groove within the region for each required through hole, and thereby eliminating distortions likely to be generated when boring is performed ultrasonically. CONSTITUTION:To bore circular through holes of 10mm in dia. in a circuit base board 1' of alumina ceramic with a thickness of 1mm, an 8mm dia. circular groove 8 is previously formed within the region A for formation of each required through hole by means of laser beam application into such a form as concentrical to the intended through hole with a depth of 0.2mm and an open width of 0.1mm. During boring, this groove 8 serves to eliminate distortion likely to be generated around a boring piece 4, and thereby to production of through holes of fine quality without chipping or cracks with good yield. Because each groove 8 does not remain after formation of the through hole, there is no problem of processing accuracy, such as location, size and shape.

Title: Humidifier
Inventor: NAGASAKA YUTAKA
IPC: F24F6/00
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To reduce number of times of supplying water by continuously operating a humidifier for a long time. SOLUTION: In this humidifier, when a power source is turned ON, a heater for automatically generating steam starts heating (step 52). When five minutes are elapsed from the start of heating, the power source of the heater is turned OFF, the heating is executed only by thermal inertia. Simultaneously, a timer is again started, a time of heat inertial operation is measured (step 55). When four minutes are elapsed, the power source of the heater is again turned ON, and the heating is again started (step 57). When four minutes are further elapsed from this, the operation is returned to the step 55, and the power source of the heater is turned OFF. Thereafter, this process is repeated until a power source of the humidifier is turned OFF or water is wasted.  At the time of heating only by the inertia, the water is not positively boiled, and hence continuous operation for longer time than the prior art can be achieved. Therefore, an effect of reducing the number of times of water supply is provided.

Title: Method of forming low-resistance silicide layer
Inventor: HIRAIDE SEIJI
IPC: H01L21/28
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To obtain a silicide layer which is lessened enough in resistance even if it is set smaller than 0.5μm in width. SOLUTION: A laminate composed of a polysilicon layer and a titanium layer laid on the polysilicon layer is subjected to a rapid thermal annealing(RTA) treatment for the formation of a silicide layer 20g. Unreacted titanium is removed, and then the silicide layer 20g is lessened in resistance through a RTA treatment. An interlayer insulating film 30 of PSG, BPSG or the like is formed covering the silicide layer 20g, and then the silicide layer 20g is made to undergo an RTA treatment again so as to be lessened in resistance. The above RTA treatment is primarily carried out for hardening the insulating film 30, so that this forming method is not increased in number of processes.

IPC: H01L21/324
Filed: 1987-10-13
Abstract: PURPOSE:To reduce the impurities included in GaAs single crystal in its production, by annealing a Ga-As semiconductor crystal for a specific time in the course of cooling the semiconductor crystal in an ampoule, which has been grown by the horizontal type boat process. CONSTITUTION:An ingot of GaAs single crystal which has been grown by the horizontal type boat method is cooled down without taking out of the quartz ampoule. In this process, the ingot is annealed for 10-250hr. At this time, the annealing is preferably carried out at about 600-900 deg.C under vacuum in case of the n-type crystal, while the p-type crystal is annealed at about 800-1,200 deg.C under an As partial pressure higher than about 200Torr. Thus, impurities in the crystal is reduced and the carrier mobility can be increased.

Title: Slip-on type earthquake resistant pipe joint and earthquake resistant pipeline
Inventor: KITAGAWA MASAYOSHI
IPC: F16L21/08
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To heighten earthquake resistance of a slip-on type pipe joint for jointing cast iron pipes without fastening. SOLUTION: A lock ring 4 is fitted in near an opening end of a socket 1, and a socket protrusion 12 is circumferentially provided at a deep part. A spigot protrusion 21 is circumferentially provided on the outer peripheral surface of a spigot 2, and the distance R from an opening-side side face 13 of the socket protrusion 12 to a deepest part 14 of the socket 1 is set larger than the disance Q from a tip-side side face 22 of the spigot protrusion 21 to its tip 23. When drawing stress works on a pipeline, the socket protrusion 12 and the spigot protrusion 21 collide with each other at the side faces so as to impede further movement, thus preventing pipe detachment completely. Because of R>Q, the tip of the spigot 2 and the deepest part 14 of the socket 1 are prevented from colliding with each other even at the time of being pushed in the reverse direction.  There is therefore no risk of rubbing off a coated face by mutual abrasion, much less the generation of deformation and damage caused by a mutual collision so as to improve earthquake resistance.

Then, the side of the InP substrate 6 is polished and an alloy 7 of gold, germanium and nickel is heat-treated after evaporation by an evaporation equipment and then chromium 8 and gold 9 are evaporated. This reduces the deterioration rate of a semiconductor laser several times compared with conventional ones.

Title: Servo device
Inventor: MIZUGUCHI HIROSHI
IPC: H02P29/00
Filed: 1987-10-14
Abstract: PURPOSE:To make control with reduced error detection ripple, by modifying a reference speed data when the sign of a speed error signal does not match with the sign of previous speed error signal. CONSTITUTION:A speed error detector 5 measures the interval of leading edge of output signal from a frequency generator 2 every time when it arrives. Classification between X and Y sections is made in a reference value correction block 10 based on an output from FF14, and a fixed reference value is corrected according to correction amounts of X and Y corresponding to respective sections. The speed error detector 5 outputs an error signal between a detected speed and a corrected reference speed data. When the sign of current error signal does not match with the sign of previous error signal, a sign matching unit 12 judges whether the error is plus or minus and increments or decrements the correction amounts for X and Y sections correspondingly.
