Title: Eliminating method of cut burr of lead electrode for electronic parts
Inventor: KITAWAKI DAISUKE
IPC: H01L23/48
Filed: 1993-03-04
Abstract: PURPOSE:To prevent current leak failure or the like by almost perfectly eliminating cut burrs extending into the periphery of the tip cut end surface of a lead electrode. CONSTITUTION:Lead electrodes 4 are accommodated in a case 9 in the manner in which the tip cut end surfaces of electrode segments 5 face the aperture of a case 9 and the vertically standing state to regulate falling-down is maintained. The aperture of the case 9 is wholly closed by a plate type body 10. The case 9 is vertically vibrated up and down in the vertically inverted state. The tip cut end surface of the electrode segment 5 is continuously impacted by the surface of the plate type body 10. The burrs (a) stretching on the periphery of the tip cut end surface of the electrode segment 5 is eliminated by the impact action.

Title: Formation of compound film
Inventor: WATANABE KAZUHIRO
IPC: C23C14/32
Filed: 1985-03-07
Abstract: PURPOSE:To improve reactivity and to change, optionally and easily, the compsn. of a film in reactive vapor deposition for which hollow cathode discharge is used, by impressing a bias voltage to a reactive gas introducing port to drawn electrons into a nozzle and activating the reactive gas. CONSTITUTION:The hollow hot cathode discharge is induced by the effect of an electric power source 7 between a water-cooled copper hearth 2 and an electron gun 4. On the other hand, DC positive or AC several tens-several hundreds V voltage is impressed between the gun 4 and a reactive gas introducing nozzle 3 by an electric power source 9. Part of the electrons in the holow cathode discharge space are thereby drawn into the nozzle 3, by which the collision is induced between the electrons and reactive gas molecules and the high-density discharge state is created. As a result, the reactive gas is partly ionized and are activated to the neutral excitation state so that the reaction on a substrate 5 is accelerated. The compd. film contg. the carbon and nitrogen at the stoichiometric compsn. ratios is thus easily formed by controlling optionally the carbon and nitrogen contents with the carbide and nitride films of not only a high-melting point transition metal but also the element requiring large activation energy.

Title: Image forming device
Inventor: ADACHI NOBUKAZU
IPC: G03G21/00
Filed: 1985-03-07
Abstract: PURPOSE:To eliminate the influence of foreign matter sticking on the surface of an image carrier by coating at least part of the image carrier surface with toner after one image forming operation is completed by an image forming device. CONSTITUTION:A photosensitive body is driven for a slight time after image formation is completed, and a primary electrostatic charger is turned on to charge a photoconductive layer while a transfer charger is held off and transfer materials are not fed. Further, a solenoid 13 is driven to rotate a cleaning device 9 counterclockwise through a level 12c and arms 12b and 12a against a spring 14. Therefore, toner sticks uniformly on the surface of the photosensitive body and is maintained until next image formation because a cleaning blade 10 does not operate because of the rotation of the cleaning device 9. Consequently, foreign matter produced in the device is hard to stick on the image carrier and even if it sticks, the foreign matter deforms in a high- humidity atmosphere and hardly exert an adverse influence upon the image formation, so images of invariably good quality are obtained.

Title: Arithmetic device of initial correction coefficient
Inventor: NAKAJIMA YOSHIO
IPC: B60C23/06
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To provide an arithmetic device of initial correction coefficients capable of reliably determining that a vehicle is moving straight and, as a result, obtaining an initial correction coefficient faithfully indicating a difference in an effective rolling radius by each initial difference between wheels. SOLUTION: On the basis of whether a time differential value R' of the inverse number of the turning radius of a vehicle lies within an allowable range RTH, whether the vehicle is moving straight or not is determined (S45). In the case that the vehicle is determined as running straight as a result, whether a difference between rotational angular speed ratios of right and left wheels is under a threshold value or not is further determined (S52). In the case that the above-mentioned difference between rotational angular speed ratios is over the above-mentioned threshold value, the vehicle is determined as moving on a road with a constant curve, and the computation of a initial correction coefficient is not performed.  On the other hand, in the case that the above-mentioned difference between rotational angular speed ratios is under the above-mentioned threshold value, the vehicle is determined as moving straight, and an initial correction coefficient is obtained (S50).

Abstract: PURPOSE:To conduct an optimum temperature control without providing a temperature sensor or the like on a head by a method wherein when recording is made by delivering ink liquid drops from the recording head, the temperature behavior of the head is estimated and predicted by calculation. CONSTITUTION:A sensor for measuring the environment temperature is provided on a main body. The temperature change of a head is estimated and predicted by a head heat time constant and matrixes, which have been previously calculated within an energy range which can be charged. Namely, the environment temperature is detected and corrected on the basis of an elapse time from a power source ON by referring to a table. Next, a present head temperature betais estimated from a temperature prediction table. With the input of a printing signal, an optimum printing object temperature alpha at the present environment temperature is evaluated from an object temperature table. A difference alpha-beta is arithmetically found, and a sub-heater is turned ON for a predetermined time found from a sub-heater control table. After the heater is turned OFF, a head temperature 72 is estimated from the table. A PWM value at the start of printing corresponding to the difference alpha-beta is found from a PWM value determination table to control the delivery amount.

Abstract: PURPOSE:To manufacture cold rolled products with better accuracy of sheet thickness by calculating two kinds of predicted value of rolling load corresponding to rolling speeds when presetting and steady rolling and performing each thickness control based on that. CONSTITUTION:On a rolling preset for improving the on-gauge rate to the target thickness of rolled coil by applying a target load value corresponding to the target thickness value calculated by the predicting formula of rolling load and a cold rolling mill 1 for metallic materials performing the thickness control when steady rolling by determining a roll opening based on that target load value, a speed dependence is given to a formula predicting the coefficient of friction in the predicting formula of rolling load. From this matter, two kinds of predicted values of rolling loads corresponding to the rolling speed preset and corresponding to the rolling speed during steady rolling are calculated. Based on that, the thickness control at the time of the presetting of rolling and the steady rolling is performed. Therefore, each function of cold rolling is made highly accurate and the cold rolling products with good accuracy of sheet thickness can be stably manufactured.
