Title: Ink jet recorder
Inventor: INADA GENJI
IPC: B41J2/055
Filed: 1990-01-25
Abstract: PURPOSE:To vibrate a meniscus formed in a dummy delivery port independently of a liquid drip delivery operation of a recording delivery port to easily remove ink mist applied to a delivery port surface at and around the recording delivery port by a construction wherein at least a part of dummy delivery ports communicate with a liquid chamber other than a liquid chamber communicating with the recording delivery port. CONSTITUTION:Dummy liquid paths 7 and dummy delivery ports 10 formed on the upper surface of a substrate 1 are provided for the air vent of an upper liquid chamber 11. At the time of recording, based on a recording signal, a heating element 8 in a recording liquid path 6 is driven to generate a vapor bubble. Subsequently to a liquid drip delivery from a recording delivery port 9 by the pressure of the bubble, ink is supplied from the liquid chamber 11 into the recording liquid path 6. On the other hand, in lower dummy liquid paths 12 and dummy delivery ports 13, at the time of recording an electrostrictive element 15 applies a required pressure to ink in the dummy liquid path 12 independently of the pressure state in the recording liquid path 6, and a meniscus 17 previously formed in the dummy delivery port 13 is projected outside the delivery port. Ink in the dummy liquid path 12 is vibrated so that the ink temporarily covers the recording delivery port 9 and thereabouts.

Title: Drive controller for motor
Inventor: HISA FUMIYA
IPC: H02P29/00
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To PLL control with a minimum power by PLL controlling a rotational speed of a motor, so that a phase difference between a rotational speed command signal and a rotational speed detection signal falls within a predetermined value, and regulating a driving voltage of the motor near a PLL- controllable minimum level. SOLUTION: An output rotational sped command signal is compared in phase with a rotational speed signal by a phase comparator. At the time of a phase difference of the both falling within a predetermined value, a phase detection signal LD is changed from a high level to a low level. A phase of a rotational speed detection signal is set to a locked state by a PLL control circuit, and a motor is set to a state for constant controlling. A voltage control circuit 23 receives the signal LD. When the signal becomes a low level or a high level, a designation signal for lowering or raising a driving voltage Vcc is output to a drive voltage regulating circuit 22. Thus, the voltage Vcc can be regulated near a lowest PLL-controllable level.

Filed: 1987-01-26
Abstract: PURPOSE:To enhance the contact density of solid particles on the leading side of heat transfer pipes facing the fluid flow so as to improve the defrosting effect on the leading side of the heat transfer pipes by fitting fins to the heat transfer pipe which forms a divider to break up air bubbles enclosed by the solid particles. CONSTITUTION:Multiple heat transfer pipes 2 are disposed in the body shell 1 in a staggered formation. Horizontally adjacent heat transfer pipes 2 are connected by fins 6, and, by drilling multiple holes 6a in the fins 6 to allow a free passage of solid particles 4, an air bubble divider 7 is formed. Thus, the fluid flow (a) and solid particles 4 are caused to positively contact with the fins 6 to improve the heat transfer performance of the heat transfer pipes 2. Further, air bubbles (b) generated in the body shell 1 by the jet of the fluid flow (a) are broken up into smaller ones when they pass through the holes 6a in the fins 6, i.e. air bubble divider 7. Therefore, the density of the solid particles 4 on the leading side is enhanced.

Title: Electron beam projector
Inventor: ITOU CHIKAICHI
IPC: H01L21/027
Filed: 1979-02-16
Abstract: PURPOSE:To increase resolution by varying the focal distance of a projection lens in accordance with the angle of deflection and thereby projecting an electron beam perpendicular to a mask at all times when the entire surface of the mask is irradiated by a narrowed electron beam in deflection scanning. CONSTITUTION:An electron beam from beam source 1 is focused by focusing lens 2 and it is impressed on deflection coil 5 via auxiliary defelction coil 3 and stop 4. Next, the electron beam deflected by deflection coil 5 is passed through projection lens 6, and it is projected on a mask of the specified pattern. In this structure, the distribution of focal points produced by optical aberrations due to manufacturing defects is measured in advance with respect to the angles of deflection, and this is stored in computer 9 as data. Next, based on this data, a command is issured from computer 9 to drive power source 8, and the focal point of lens 6 is corrected by causing it to synchronize with the deflection current of coil 5. By this, the resolution becomes about 1/2, so that the projection area can be doubled and image distortion can be eliminated.

Title: Time striking structure of clock
Inventor: NAKAMURA NORIHIKO
IPC: G04C21/06
Filed: 1980-02-13
Abstract: PURPOSE:To reduce the loss of the gear trains of a clock to be caused by the  charge, by mounting an escape pawl to the control lever which opens and closes the contact point of the time striking structure and arranging so that the load of the control lever do not transmitted directly to the time cam wheel. CONSTITUTION:When the time cam wheel revolves to push up the contact board 22a to the arrowed direction, the end part of the contact board 22a touches the escape pawl 60 which is supported by the control lever 50. At this time when the contact board 22a is pushed further upward by the time cam wheel revolution, as the escape pawl 60 is supported by the contact board 22a, only the escape spring 64 connected to the escape pawl 60 is charged to the contact board 22a. By arranging so that the change of the escape spring 64 is considerably smaller than that of the charged spring, the charge loss to the time cam wheel by the contact board 22a becomes considerably smaller. Therefore no undersirable effects are given to the clock gear trains.
