Title: Joined clad plate and its manufacture
Inventor: FUJII HIROMITSU
IPC: B23K26/32
Filed: 1992-10-27
Abstract: PURPOSE:To obtain the joined clad plate where functions and characteristics which base plate material and material to be clad have respectively are not marred by allowing the same materials to abut on each other, welding only high melting point side material and further, welding low melting point side material. CONSTITUTION:A butt part 8 of the high melting point material 4 is irradiated with a laser beam and welded up to the depth (d). At this time, since the beam is narrowed down finely and the butt part 8 can be welded when laser beam welding is used, a value of (a) of a bead part 6 becomes smaller desirably. The butt part 8 of the low melting point material 5 is then welded up to the depth (d') by laser beam welding. A value of (a') of a bead part 7 also becomes smaller in the same way in this case. Consequently, cladding is attained in the bead parts 6 and 7 and the whole joined clad plate 1 after welding including the bead parts 6 and 7 holds various properties which the clad plate has before welding.

Title: Inspection method for recording head and recorder
Inventor: KANDA HIDEHIKO
IPC: B41J2/05
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To provide an inspection method for recording head, and a recorder, in which the ink jetting state of a recording head can be detected with high accuracy. SOLUTION: Temperature rise and drop of a recording head jetting no ink incident to heating thereof are measured and temperature rise and drop of the recording head at the time of preliminary ink jet are also measured. A first value indicative of the difference between temperature rise and drop when ink is jetted normally in the preliminary ink jet is determined along with a second value indicative of the difference between temperature rise and drop when ink jet from the recording head is rejectable. Based on these values and a third value indicative of the difference between temperature rise and drop measured at the time of heating the recording head, a threshold value indicative of occurrence of rejectable ink jet is calculated.  Subsequently, preliminary ink get is conducted again and the difference between temperature size and drop of the recording head thus obtained is compared with the threshold value. Finally, a decision is made whether ink is jetted normally or not from the recording head based on the comparison results.

Title: Image forming device
Inventor: FUJII HARUO
IPC: G03G15/06
Filed: 1991-11-28
Abstract: PURPOSE:To prevent the density of a developed image from being changed because the electrostatic charged amount of toner is changed by humidity change and to prevent the occurrence of fogging by providing a means for controlling the ratio of the duration of the 1st phase of oscillating bias voltage to the duration of the 2nd phase thereof corresponding to detected humidity. CONSTITUTION:In the case of low humidity, image density becomes low, and in the case of high humidity, the image density becomes extremely high and the fogging occurs, so that the uniform image is not obtained. As a solution to such a problem, the waveform of bias voltage A-C impressed on a roller is set so that the duration T1 of electric field when the toner flies from a developing roller to an image carrier may be relatively long (A) in the case of low humidity, and the duration T1 of the electric field when the toner flies to the image carrier may be relatively short (C) in the case of high humidity. In the phase of T2 of the developing bias voltage A-C, force in a direction from the image carrier toward the developing roller is applied to the negative electrostatically charged toner, and while the phases T1 and T2 are repeated, development is finished as a gap between the image carrier and the developing roller is extended.

Title: Track access device
Inventor: INADA HIROSHI
IPC: G11B21/08
Filed: 1987-12-11
Abstract: PURPOSE:To attain precise track access by interpolating a track clock pulse by means of the pulse of a prescribed frequency when an optical spot crosses an area where a track guide groove on an optical disk does not exist. CONSTITUTION:When the optical spot 8 crosses the area where the track guide groove on the optical disk 4 does not exist, a track clock pulse generator 5 generates the track cross pulse 13 from a track error signal 11 and an interpolation pulse generation circuit 7 simultaneously generates the interpolation pulse 14 of the track cross pulse. Thus, a preformat area where the accurate track error signal cannot be generated receives a preformat area signal 21 showing the preformat area from an external part, and transmits the interpolation pulse 14 of the prescribed frequency to a track shift control circuit 1 in place of the track cross pulse 13 by a switch 6. Thus, accurate track access is attained.

Abstract: PROBLEM TO BE SOLVED: To execute an emergency shutdown of a circuit safely and securely with a simple and inexpensive structure, by sealing the space between an ignition point of igniting parts enclosing explosives and a fracture part of a current carrying path. SOLUTION: When an airbag signal is produced by collision of a vehicle and inputted in a harness ECU, the harness ECU executes power supply to this circuit breaker through a lead wire 36. When the circuit breaker 12 receives the power supply, the circuit breaker 12 heats a filament of igniting parts 12 and ignites explosives 33, to thereby explode them. The explosion force is concentrated from a sealed space S onto a fracture part and is made to function, and elementary metals burning by the ignition of the explosives 33 are also blown to the fracture part. The fracture part is broken at a fracture groove 30, and opened projectingly toward the bottom 23a side of a case body 23 with each bent groove 31 as a fulcrum.  Hereby, forced shutdown of a power source supply circuit, where a current carrying path 21 having the fracture part is interposed, is executed and power supply to almost all of loaded electric equipment excepting a part of loaded electric equipment is cut off simultaneously.
