Title: Electrophotographic copier
Inventor: IWAI FUMIO
IPC: G03G21/20
Filed: 1978-01-13
Abstract: PURPOSE:To enable driving controlling of an antidewing heater to be performed readily and surely by so arranging the copier that its mechanical-electrical loading and current supplying of the antidewing heater may be selectively operated. CONSTITUTION:The normally open fixed contact 1a of a main switch 1 is connected to a mechanical-electrical load 2 for receiving power supply for the purpose of copying operation and the normally closed fixed contact 1b is connected to an antidewing heater 3. During operation of the copier whose main switch 1 has been turned on, the temperature in the machine rises owing to evolution of heat from the fixing heater, exposure lamp, etc. and the dewing in the machine is prevented by these electrical loads. On the other hand, while the copier whose main switch 1 has been reset is not in operation, current supply to the antidewing heater 3 is automatically accomplished, thus the temperature in the machine is maintained at a suitable temperature at which dewing may be prevented.

Title: Method of heat-treating semiconductor substrate
Inventor: NAKAGAWA YASUHITO
IPC: H01L21/26
Filed: 1989-01-09
Abstract: PURPOSE:To obtain, with good reproducibility, a high-concentration and steep profile of a carrier concentration by a method wherein a speed to heat a semiconductor substrate by means of a short-time annealing method using an infrared lamp is made lower than a specific value. CONSTITUTION:When a semiconductor substrate is heat-treated by means of a short-time annealing method using an infrared lamp, a speed to heat the semiconductor substrate is made lower than 20 deg.C/sec. When the heating speed is made low, an annealing time becomes longer; accordingly, heat supplied to the substrate is increased; an activation rate is increased; a high-concentration profile can be obtained; a performance of a GaAs LSI can be made higher.

Title: Production of ultrasonic probe
Inventor: NAKATANI SENZOU
IPC: H04R17/00
Filed: 1982-01-13
Abstract: PURPOSE:To produce a probe having an optional form or hardness in a simple  way, by adding a strip-off process for an oscillator array connected with a filler. CONSTITUTION:A flat oscillator 5a having electrode on the upper and lower surface is adhered tentatively on a cutting stage 5b by means of wax, etc. The oscillator 5a is cut, and the silicone rubber, etc. having the prescribed adhering force and softness is filled and hardened into the cut groove. Then the wax is melted, and the oscillator 5a is stripped off fromthe stage 5b. In this case, a metallic foil 5d is put between the oscillator 5a and the stage 5b in case the cut groove is formed also to the stage 5b. Then the filler put into the stage 5b is cut while melting the wax. In such a way, an oscillator having many elements 5e adhered with the filler is obtained. Such an oscillator can move freely at a part 5f of the filler and then adhered to a concave packing material 5g. Thus a probe is produced.

Title: Display input device and input indicating method
Inventor: KANAYAMA EIJIRO
IPC: G06F3/048
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To provide a display input device and an input indicating method to show plural types of information display items within a display screen of a display means and also to decrease the wrong moved input operations to the movement performed between the prescribed information display items. SOLUTION: A display screen can be divided into plural areas (a menu switching block, a set input display block and a device switching block). Then the movement that is performed by a pointer means 15 among those divided areas is limited and a indicated position can be moved among the divided areas only by a divided area-only movement means 17 different from the means 15 on the display screen which is divided into plural areas to show plural types of information display items. Thus, it's possible to prevent such a case where the setting condition of another processor is changed by mistake or the operation of a processor is started and stopped by mistake.

Filed: 1982-01-13
Abstract: PURPOSE:To make the economizing of blank material alloys possible without reheating and to cool a steel strip with good shapes by incorporating an underwater jet cooling method using hot water of specific temp. to a primary cooling method after soaking. CONSTITUTION:In a primary cooling stage of titled treatment consisting of heating, soaking, primary cooling and post-treating stages, the steel strip S after holding at temp. Ac1-Ac3 is dipped in static hot water W kept at 60-75 deg.C. In addition, the hot water W is sprayed as jets from underwater headers 23 to both sides of the steel strip in the water W. Then, the steel strip can be cooled immediately down to the Ms point lower than 200 deg.C at 100-500 deg.C/sec cooling rate. Since the steel strip can be cooled without cutting the nose of CCT curves, the blank material alloys can be economized. If the steel strip after soaking down to 710-450 deg.C is slowly cooled with gas jets in the fore stage of cooling with hot water jets in adapting said cooling, the inflection point of two-stages cooling is changed, whereby the economizing effect of the blank material alloys is high and the shape of the steel strip is assured.

IPC: G06F1/02
Filed: 1993-01-12
Abstract: PURPOSE:To accelerate calculation by normalizing the range of a source parameter and approximating remaining error with a Chebyshev's polynomial, for example. CONSTITUTION:When calculating the approximate value of a function which input parameter is + or -infinity  while being vertically counded (+ or -1), the arithmetic of u=1/sqrt(1) is utilized, a range -infinity <x<+infinity  of the source parameter is normalized to -1<u<+1, and approximate calculation is performed on the two stages to approximate the remaining error with a prescribed approximate formula such as a Chebyshev's approximate formula (2), for example. Then, a hyperbolic tangential function (tanh function) is approximated by using the approximate calculating method of this function. Further, when the objective function is an odd function, the arithmetic on the first stage is x/sqrt(x<2>+alpha<2>) but when the objective function is an even function, the arithmetic is alpha/sqrt(x<2>+alpha<2>) and the arithmetic on the second stage is performed by extending the Chebyshev's polynomial. Then, the approximate calculation of this function is executed by a single instruction/plural data (SIMD) type parallel neuro computer and defined as the values of sigmoid functions of respective neuro elements.
