Title: Fining method for welding metal
Inventor: KAWAGUCHI SEIICHI
IPC: C21D9/50
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To provide a method for the improvement of an ultrasonic testing property(UT property) as the same degree as a base material by eliminating columnar crystal of a welding metal in the welding of a stainless steel and fining the crystal. SOLUTION: A method for fining the welding metal is executed by holding at 800-1250 deg.C for 30-300 sec after a strain of 2-15% is applied with a hot-tension at 800-1250 deg.C to the welding metal at the time of executing the welding of the stainless steel. Concretely, the hot tension after a TIG welding is complated is executed to each layer in a bevel of the stainless steel (SUS316)-made round bar or plate and the plastic strain of 2-15% is given after this round bar or plate is partially heated with a high frequency induction coil. In the case of being less than 2% of the plastic strain, the effect of the crystal fineness is lowered, and in the case of exceeding 15%, particularly 20%, the resistance of the plastic deformation is increased and the device loading the strain is too large to be plactical.  The heating temp. therein, in the range from 800 deg.C of the lowest temp. starting recrystallization to 1250 deg.C starting development of coarse grain, is desirable. Successively, a solution treatment which holds to the recrystallizing temp. (e.g. 1100 deg.C) for >=30 sec and recrystallizes the welding metal, is applied to fine the crystal.

Title: Resonance tunneling barrier diode
Inventor: INADA TSUGUO
IPC: H01L29/88
Filed: 1986-11-18
Abstract: PURPOSE:To combine large peak current density and a current density ratio by injecting electrons to a quantum well structure from a second n-type gallium arsenide layer. CONSTITUTION:A resonance tunneling barrier diode has a structure in which n-type GaAs layers 2, 8 as injection electronic sources are grown onto AlGaAs/ GaAs/AlGaAs quantum well structure in an epitaxial manner, interposing a second non-doped GaAs layer 6 and a third non-doped AlGaAs layer 7. The interposed non-doped AlGaAs/GaAs hetero-junction has an effect of obstructing the diffusion of an impurity such as Si introduced to the n-type GaAs layers 2, 8 as the injection electronic sources, and a remarkable impurity-diffusion preventive effect is acquired even when the AlGaAs layer 7 consists of one or two atomic layer and the GaAs layer 6 is shaped in approximately 10Angstrom . The shape of the transmission coefficient of a resonance tunneling barrier hardly changes even when the AlGaAs/GaAs hetero-junction thin in this extent is interposed, and valley current density JV is reduced largely without minimizing peak current density JP, thus remarkably improving a maximum/minimum current density ratio JP/JV.

Title: Disinfector for contact lens
Inventor: YAMAUCHI MASAKATSU
IPC: G02C7/04
Filed: 1985-12-03
Abstract: PURPOSE:To maintain precisely a required disinfection temperature by combining a temperature sensitive magnet with a reed switch adjacently opposed to the magnet to directly detect and control the temperature in a disinfection room. CONSTITUTION:When contact lenses 3, 3' and a storage solution 12 are injected into the disinfection rooms 4, 4', a cover 2 is closed, the disinfection rooms 4, 4' are engaged with storage ports 8 in the body 8 of the disinfector, and a switch 11 is turned on, a heater 10 positioned on the bottom of disinfection case 1 starts heating. The temperature is detected by the temperature sensitive magnet 5 fitted to the cover 2, and when the detected temperature reaches the curie point of the magnet 5 which is set up to the same temperature as the required disinfection temperature, magnetism is changed, the reed switch 6 fitted to the adjacently opposed position is turned off and current supply to the heater 10 is stopped. Since a relay contact S1 is kept at OFF state even if the temperature is naturally cooled and the magnetism is changed so that the magnet 5 turns on the reed switch 6, heating is not started until the switch 11 is turned on.

IPC: G06F11/30
Filed: 1988-10-31
Abstract: PURPOSE:To improve the clocking accuracy of monitor time by counting up a clock based upon a clock signal inputted to a CPU. CONSTITUTION:A clock signal generated from an oscillation circuit 103 is used as a reference clock signal 108 for a CPU part 101 and a counter 102 inputs and counts up the clock signal 108 or a clock signal 111 obtained by dividing the frequency of the clock signal 108. When a program stored in a ROM 101a can not be normally executed due to the runaway or the like of the CPU part 101, data are not set up in a register 106, the initialization of the counter 102 can not be executed, and when the count value of the counter 102 reaches a prescribed value, a signal 110 is turned to a high level, a reset interruption is inputted to the CPU part 101 through an OR circuit 107 and the CPU part 101 is reset. Since the reference clock of the CPU is used as a counting clock of the counter, the monitor time of a watchdog timer can be stabilized.

IPC: H04B7/06
Filed: 1989-10-20
Abstract: PURPOSE:To increase an information transmission quantity per unit time by always monitoring the reception levels of signals received through plural antennas and executing diversity in a base station. CONSTITUTION:Receivers (two receivers 251 and 252) are provided in correspondence with plural antennas and the antennas transmitting outgoing signals are selected with the estimation of the reception level of mobile station by using the reversibility of a transmission line from the reception levels of respective incoming signals. Then, respective reception levels of the moving stations in a signal length T are predicted, and transmission diversity for switching the antennas transmitting the outgoing signals when the reception levels are crossed is executed. Thus, a preamble signal and a postamble signal, both of which are conventionally used in level detection are eliminated and the information transmission quantity per unit time can be increased.

Title: Pre-processing method for recognition of linear graphic
Inventor: SUZUKI TOSHIHIRO
IPC: G06T5/30
Filed: 1989-10-20
Abstract: PURPOSE:To improve the smoothing effect, to reduce the overall processed variable for recognition of a linear graphic, and to improve the recognizing accuracy by apply ing a smoothing operation to only a boundary point to turn a tilt discontinuous point train into a tilt continous point train. CONSTITUTION:The feature including the tilt of a boundary point is extracted out of the image data on a linear graphic. Then the i-th boundary point p(i) which is noticed after tracking a boundary point by means of the extracted feature as the pre-processing to recognize the linear graphic is defined as a tilt discontinuous point when the codes are different from each other between the difference dang(i) and dang(i + 1) between an angle ang(i - 1) showing tilting direction of the point p(i) and the angles ang(i - 1) and ang(i + 1) showing the tilting directions of the boundary points p(i - 1) and p(i + 1) which are adjacent to the point p(i). Then a tilt discontinuous point train including the tilt discontinous points is corrected into a tilt continous point train. Thus, the tilting direction of the boundary point is smoothed. Therefore only a black/white boundary point is smoothed instead of all picture elements of the linear graphic. Thus, the processed variable is reduced and a smoothing operation is carried out so as to turn a tilt discontinuous point train into a tilt continuous point train. Then the smoothing effect is improved.
