Title: Printing device
Inventor: YAMAMOTO TAKESHI
IPC: B41J29/46
Filed: 1993-02-02
Abstract: PURPOSE:To permit efficient charging without generating overcharge by a method wherein a charging time is determined based on a past historical data. CONSTITUTION:Upon charging a nickel-cadmium battery 43, a CPU 31 compares the input voltage of a power supply circuit 45 with the output voltage of the nicad battery 43 and, further, when an input from a key board 3 is not inputted for a first predetermined period of time while a thermal head 39 and an interface 41 are not under operation, the CPU 31 operates a second predetermined period of time necessary for charging the battery based on a historical table 35e and charging is effected for the second predetermined period of time. On the other hand, when a letter is inputted even during charging, the charging is stopped. As a result, the charging time is determined based on the past historical data whereby efficient charging can be effected without generating any overcharge.

Title: Time constant circuit
Inventor: MORIWAKI ISAMU
IPC: H03K5/13
Filed: 1989-01-24
Abstract: PURPOSE:To alter the time constant of an input signal at a small amplitude at the time of charging and discharging by controlling a transistor(TR) by means of a charging or discharging current to/from a capacitor, and using the rectifying operation of the TR. CONSTITUTION:The collector current of a TR Q1, where a high level input voltage VIN is inputted, is reduced, the base potentials of TR Q5 and Q7 are decreased and increased, and a TR Q6 is turned on. The current is supplied form an input terminal 4 to the parallel circuit between the series circuit of a resistance R1 and the TR Q6, and a resistance R2, and a capacitor CL at capacity CL is charged by the time constant, which is determined by {R1XR2/(R1+R2)}XCL. When an input VIN changes to a low level, the TR Q6 is cut off, the capacitor CL is discharged through the resistance R2, and the time constant is set at R2XCL. By the rectifying operation of the TR Q6 substituting for a diode, since the saturation voltage between the collector and emitter is sufficiently smaller than a forward directional voltage drop, the charging/discharging time constant of the input signal whose fluctuation level and amplitude level are small can be made different.

Title: Sealing process for ring fluorescent lamp
Inventor: MARUYAMA FUMIROU
IPC: H01J9/40
Filed: 1982-02-03
Abstract: PURPOSE:To easily carry out the nodal part forming process by means of a mold, by adopting a sealing process which has dissolved the problems such as the material loss and the increase of sealing process caused by Carlet system and patseal system respectively, and installing a padding (thick part) on the sealed part during this sealing process. CONSTITUTION:First, the bulb wall is pre-heated by the low flame of a burner 40, then strongly heated to be softened by the high flame thereof so that the diameter of a nearly central part of the bulb wall is more shortened than that of a flare part 34, and then the burner is moved toward the tube end in such way that a flame hole 41 is allowed to be placed at a position facing the flare part 34; when a bulb 30 is heated and softened, the tube wall facing the flare part 34 is shortened in its diameter, and the tube wall is hermetically welded to the flare part 34. Further, an opening brim 30a is heated and formed in a thick part 51. While the thick part 51 is still in a soft state, a mold 70 is set and a compressed air is fed into the bulb 30 so that the pressure inside the bulb is increased relatively to the outside pressure, and a nodal part 80 which fits to the inside surface configuration of the mold 70 is formed.

Title: Superconducting magnet device
Inventor: JIZO YOSHIHIRO
IPC: H01F6/02
Filed: 1986-01-29
Abstract: PURPOSE:To prevent a superconducting coil from burning due to a breaking the connecting terminal insulation, by externally taking out a high voltage by connecting the intermediate tap voltage measuring lead wire having risk of generating the high voltage to a connecting terminal other than those for the voltage measuring lead wires at the beginning and ending of the winding. CONSTITUTION:Quenching the superconducting coil 2 excited up to its rated current generates both inductive and resistive voltages among the windings. A voltage between the beginning and ending points of the windings of superconducting coil 2 becomes equal to a product of resistance value of protective resistance 15 and coil current by offsetting each other between the inductive and resistive voltages, thus not leading to an overvoltage. While, a voltage between the intermediate tap terminals can become fairly high. The voltage measuring lead wires 12a, 12b are, therefore, to be gathered into a same measuring pipe 11a and connected to each pin of the same No.1 connecting terminal 12a, while the intermediate tap voltage measuring lead wire 10c only to another No.2 connecting terminal 12b. For this reason, even generating a high voltage between the voltage measuring lead wires 10a, 10b at the beginning and ending points of the windings can prevent such a hazard of accident as coil burning and the like.

Title: Die casting device
Inventor: TAKEMURA SOUKICHI
IPC: B22D29/00
Filed: 1981-02-04
Abstract: PURPOSE:To prevent the failure, damage and deformation of castings by dropping the casting molded in dies into a receiving box wherein powder and granular materials such as sand are contained and further additionally supplying the powder and granular material into said box. CONSTITUTION:A cast iron casting M molded of dies consisting of a stationary die 11 and a movable die 12 is ejected by means of ejection pins 13 after spacing of the die 12 and is dropped. In the dropping position of the casting M, an empty box 21 is beforehand carried therein and a specified amt. of sand S1 is supplied from a conveyor 22. After the casting M drops into the box 21, the conveyor 22 operates again according to this and supplies the sand S2 additionally onto the casting M in the box 21. Thereafter the box 21 is carried out laterally by means of a conveyor or the like. Thereby, the impact upon the casting M during dropping is relieved and the failure and damage to the casting M are prevented. Since the surface of the casting M is coated with the sand S of the same quality, the cooling rates in the respective parts are averaged and the deformation owing to the nonuniform cooling is prevented.

Title: Intake air flow control device for internal combustion engine
Inventor: KANAI HIROSHI
IPC: F02D41/12
Filed: 1989-01-27
Abstract: PURPOSE:To avoid enrichment in mixture by renewing a deposit correction factor when mixture is lean at the time of accelerating operation, and thereby controlling intake air flow at the time of decelerating operation based on said deposit correction factor. CONSTITUTION:It is judged by a lean judging means 51 based on the result of the detection made by an accelerating operation condition detecting means 50 whether or not mixture is lean at the time of accelerating operation. And when mixture is found to have been lean, an injection quantity control means 52 renews a deposit correction factor so that driving of a fuel injection valve 12 is controlled to increase the quantity of fuel injection at the time of accelerating operation. On the other hand, when a decelerating condition is detected by a detecting means 53, an intake air flow control means 54 drives a throttle valve 15 is response to the deposit correction factor renewed at the time of accelerating operation so as to control the intake air flow. This constitution thereby prevents output torque from being developed at the time of decelerating operation, and also can prevent mixture from being rich.

Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To arrange a plurality of probe channels with high density by suppressing reverse direction signals in the probe channels. SOLUTION: An analog voltage probe 106 comprises a plurality of probe channels 340 and a reverse direction signal suppressing means 270. Each of the channels 340 has a probe input 107, a lead 110 and a probe amplifier circuit which is a part of a multiplexer IC 240. The IC 240 comprises 18 inputs 241 one of which is capable of being connected one of or both of outputs, e.g. it is connected only to the channel #9. The means 270 comprises an output impedance matching resistance 212 that matches impedance of the lead 10 in the reverse direction and is provided each of the channels 340 so that the signals in the reverse directions are suppressed. As a result, nine independent probe channels are united to one body, then the reverse direction signals are suppressed. Therefore, it is possible to allow the nine channels to be built in a high density circuit package such as an IC chip.
