Title: Ink jet recorder and recording method
Inventor: IKEDA KOJI
IPC: B41J2/205
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To suppress fluctuation in the ejection quantity of ink drop by operating a pressure applying means when an ink jet head and a recording sheet are being moved relatively. SOLUTION: Since small and large ink drops are combined on a recording paper 41 when they are ejected simultaneously, the small and large ink drops fly substantially linearly until hitting on the recording paper 41 contrary to a case where they are combined in the air and they hit on the recording paper 41 while passing through same flight passage as the case where only a small or large ink drop is ejected. When a dot recorded only with a small or large ink drop is contiguous to a dot recorded with both small and large ink drops, the ink drops can hit on the recording paper 41 without causing any relative positional shift between both dots. Since small and large ink drops are combined at same position on the recording paper 41, a substantially right circle dot is recorded with both ink drops.

Title: Fan controlling system
Inventor: SHIMIZU NORIAKI
IPC: G06F1/20
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To eliminate automatically the clogging due to accumulated dust by changing the rotational direction of fans with the aid of a controller at every fixed period of time. SOLUTION: During a period when fans b(1)-b(3) are rotated with the aid of a controller (a) so that air flows in a direction from air suction ports c(1)-c(3) toward air outlet ports d(1)-d(3), a quantity of dust to be accumulated at the air suction ports c(1)-c(3) is increased with the lapse of operation time. Then, the fans b(1)-b(3) are reversely rotated with the aid of the controller (a) so that air flows in an opposite direction while using the air outlet ports d(1)-d(3) as air suction ports and using the air suction ports c(1)-c(3) as air outlet ports. During this operation of reverse rotation, dust accumulated at the air outlet ports c(1)-c(3) is discharged into ambient air, and the quantity of dust is reduced with the lapse of the reverse operation time. By repeating this operation, the clogging can be automatically eliminated.

Abstract: PURPOSE:To improve the flow of solder so as to enhance airtightness of a discharge lamp by controlling the diameter of a cross member, which distributes molten glass solder, in relation to the inner diameter of a luminous valve at the time of sealing the opening end of the luminous valve with a plug. CONSTITUTION:The opening end of a luminous valve 1 made of transparent ceramics is sealed with a ceramic plug 2A together with a lead-in wire 4 equipped with an electrode 5A using a glass solder 7 to form a luminous valve such as a high pressure sodium-vapor lamp. In this process, the opening end is provided with a glass solder 7, a disk-shaped plug 2A, a lead-in wire 4 and a cross member 6 which serves as a hanger during the sealing process and whose diameter dmm is regulated to satisfy the condition D<=14.5d, where Dmm is the inner diameter of the valve 1. Then, sealing is achieved by heating the opening end. Therefore, better flow of the glass solder can be obtained and yield can be improved by regulating the diameter of the cross member 6 to be rather thicker.

Title: Camera
Inventor: SATO SHINICHI
IPC: G03B17/42
Filed: 1988-10-14
Abstract: PURPOSE:To reduce the number of parts and to simplify a release mechanism by providing a means which stops a release button from returning to an initial position with a film winding operation upon the completion of photographing the last photographic frame. CONSTITUTION:With respect to a film integrated camera in a photographing enable condition, photographing is performed by pressing the release button 61, which is held in its operating position. By winding a winding knob 11 counter clockwise, a picture film is carried by one picture plane and the rotation of the release button actuates shutter charge and film counter; the release button 61 returns to the initial position in order to prepare a photographing enable condition for a subsequent frame. Since the release button does not return to the initial position from the position in which the last photographic frame is rotated even if the picture film is wound, the release button does not operate, and photographing is not performed. This simplifies a constitution.

Abstract: PURPOSE:To easily measure salinity even during a run by fitting a couple of ultrasonic wave transducers at specific positions undersea below a ship body and performing arithmetic processing based upon the speed of an ultrasonic wave, the temperature of sea water, and the depth of the ultrasonic transducers. CONSTITUTION:The couple of ultrasonic wave transducers 111 and 112 are fitted at the specific undersea positions below the ship body at a fixed distance from each other. Further, the water temperature sensor 21 of a water temperature measurement part 2 is fitted undersea to the ship body.

Abstract: PURPOSE:To obviate a conveying pipe line of the working fluid and an expansion valve for aiding changes in phase in order to compact the device constitution and stabilize the actuation by making a working fluid in a closed container adsorb on an adsorbent, holding it in a fiber metal plate or maintaining it at a state of gaseous phase. CONSTITUTION:A number of adsorbent heat exchange plates 10 and a number of fiber metal heat exchange plates are sealed into a plurality of closed containers 15A and 15B together with working fluids respectively to form a plurality of heat exchange chambers A and B. Both the heat exchange chambers A and B are formed by dividing the inside of a casing 11 with a partition wall 16. For example, in one heat exchange chamber A, an overheating medium 17 is made to pass through a pipeline (a) of the adsorbent heat exchange plates 10 (desorption block i) while cooling water 18 passes through a pipeline (b) of the fiber metal heat exchange plates 11 (adsorption block ii). As a result, the heating medium 17 is cooled being given a desorption heat while the cooling water 18 is heated receiving condensation heat. This obviate the need for a conveying pipeline of the working fluid and an expansion valve for aiding changes in phase.

Title: Semiconductor storage device
Inventor: ISHII YASUHIRO
IPC: G11C11/414
Filed: 1989-10-04
Abstract: PURPOSE:To prevent a signal amplitude from being affected by means of the change of a power voltage by setting a reference potential to be the power source of bit line loads and the power source of word drivers. CONSTITUTION:The power source of the word drivers Q11 and Q12, the power source of the loads Q5 and Q6, and Q7 and Q8 of the bit lines BL and the inverse of BL are set to the reference potential Vs. The outputs of COMOS invertors Q5, Q6, Q7 and Q8 give the potentials of the bit lines BL and the inverse of BL. When the power sources are the reference potential Vs and a power source low potential Vss, they are not affected by the power voltage and therefore the potential of the bit lines are not affected by the fluctuation of the power voltage. When the power source of CMOS invertors Q11 and Q12 driving the word line WL are Vs and Vss, the word line WL is not affected by the fluctuation of the power voltage and the resistances of transfer gates Q3 and Q4 are not affected. Thus, a read current is not affected by the power voltage. Thus, the potential of the bit lines and a current flowing at the time of reading are not affected by the fluctuation of the power voltage.
