Title: Method for driving ink-jet apparatus
Inventor: TAKAHASHI YOSHIKAZU
IPC: B41J2/12
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To make ink drops ejecting speed hardly fluctuate due to temp. and improve the quality of printing. SOLUTION: The second driving wave shape 10 consisting of only the first pulse signal A for ejecting ink drops is such a wave shape that suppresses the heating value of a head and decreases ejecting speed of the ink drops. The first driving wave shape 20 consisting of the second pulse signal B which does not eject the ink drops and the third pulse signal C which ejects the ink drops is such a wave shape that increases the heating value of the head and increases the ejecting speed of the ink drops.  In a low temp. region where the ink becomes highly viscous, driving is performed by using the second driving wave shape 10 and in a high temp. region where the ink becomes lowly viscous, driving is performed by using the first driving wave shape 20 to decrease changing in temp. of the head and the ink and to decrease changing in ejecting speed of the ink drops caused by changing in surrounding temp.

Title: Semiconductor device having reinforced radiation resistance
Inventor: SAKAMOTO MITSURU
IPC: H01L21/76
Filed: 1984-01-24
Abstract: PURPOSE:To improve radiation resistance by isolating source-drain regions formed in a self-alignment manner and a gate region so as not to be brought into contact with an insulating isolation region between elements. CONSTITUTION:A gate electrode 202 is formed in a region surrounded by an insulating isolation region 201 in an element. N<+> regions 203 in which source- drain are shaped are formed to a shape separate from the region 201 and to a shape that the regions 203 are self-aligned with the electrode 202. Consequently, the increase of junction leakage is inhibited because the regions 203 formed to the surface of an Si semiconductor substrate 206 are cut off from thick insulating oxide films 207 and a P type region having comparatively high concentration by isolation regions 210 coated with interlayer films 209 as shown in a sectional structure figure cut by a line a-a. Channeling leakage currents between the source-drain are removed because the regions 203 are isolated from the films 207 and regions 208 by regions 211 as shown in sectional structure cut by a line b-b.

Title: Troidal coil
Inventor: KITAZAWA KAZU
IPC: H01F6/06
Filed: 1980-02-06
Abstract: PURPOSE:To unify a surfacial pressure applied on an insulation key and improve strength reliability by providing a cross-section area on the internal periphery larger than that of the external periphery of an insulation key connected, with a prearranged surfacial pressure, to a coil conductor through the intermediary of an insulation key. CONSTITUTION:An insulation key 1d fixing the winding start end of a coil conductor 1a, the winding finish end and the adjoining coil conductor 1a with a required surfacial pressure is formed with a step in such manner that the relationship betwen the thickness h1 of an insulation key on the internal dia. side and the thickness h2 of an insulation key on the external dia. side may be h1>h2. In addition, in the peripheral direction of the insulation key 1d, the length of its internal dia. side will be larger than that of the external dia. side so as to form a step in the diametrical direction. Thus the cross-section area on the internal periphery of the insulation key 1d is constituted larger than that of the external periphery. Under this constitution, it is possible to equalize a surfacial pressure on the internal dia. side and a surfacial pressure on the external dia, side which act between the coil conductor 1a and the insulation key 1d by a tension in the peripheral direction due to an electromagnetic force brought to bear on a troidal coil and therefore, eliminate an unnecessary force.

Title: Fixed gain switching circuit
Inventor: FUTADO KIYOTAKA
IPC: H03G3/00
Filed: 1980-02-05
Abstract: PURPOSE:To increase the reliability for a switch of the fixed gain, by switching the pilot signal contained in the transmission signal before it is converted into a DC. CONSTITUTION:Only the pilot signal is extracted out of the transmission signal applied to the terminal 1 through the BPF3, and the pilot signal is detected through the level detection circuit 8 via the amplifying circuit 4 and the rectifying circuit 5. When the circuit 8 detects the pilot signal lower than the reference level, the switch 10 is switched to the oscillator 11 in the own station. Then the pilot signal of the reference level of the oscillator 11 is applied to an automatic gain control circuit via the expanding circuit 7 to fix the output level. Thus the switching is facilitated with a reduced quantity of power consumption since the pilot signal is switched before it is converted into a DC.

Title: Commutating circuit of brushless dc motor
Inventor: UORUFUGANGU RATSUBUIRU
IPC: H02P6/182
Filed: 1987-01-23
Abstract: A control circuit for a collectorless d.c. motor, without a commutation sensor, and comprising a stator with a multiphase system and a permanent-magnet rotor. The commutation state of the motor depends on the voltages induced in the stator windings. A comparison signal is generated which indicates whether the sign of that winding voltage which is not connected to a direct current source by means of the circuit electronic switching elements is in conformity with a predetermined sign which depends on the instantaneous commutation state. This comparison signal is inhibited during those time intervals in which transient effects which may cause spurious zero crossings occur in the windings as a result of the electronic switching elements being turned off. The switching elements are always switched one commutation step further if the comparison signal does not have the appropriate sign.
