Title: Cam gear type control mechanism
Inventor: KOGA NOBUYUKI
IPC: G11B15/18
Filed: 1990-11-13
Abstract: PURPOSE:To simplify a mechanism and improve reliability by constituting the mechanism of a cam gear having a teeth part provided with teeth missing parts, a cam part to control and a cam part to be controlled, a trigger lever having a delay blasting means and an electromagnetic means to keep the trigger lever in a blocking position. CONSTITUTION:A control mechanism 7 has a cam gear 10, a driving gear 25, a trigger lever 27 and an electromagnetic plunger 36. Teeth parts 18a, 18b and 18c and teeth missing parts 19a, 19b and 19c are arranged on the gear 10. A cam 20 to control is arranged on a main part 16, and a push-pressed pin 9 arranged on a slider is positioned inside a cam part 20 so as to slide freely. The push-pressed pin 9 is push-pressed according to positions of the cam 20 to control, so that a position of a mode switching slider can be determined. When lock on the cam gear is released, its position moves from a blocking position of the trigger lever to a non-blocking position so that initial rotation is carried out, and since return of the trigger lever is carried out by means of the driving gear, special parts are not required so that its structure can be simplified. The levers can be regulated quite accurately by means of a cam groove to control, so that reliability can be improved.

Title: Recording and reproducing system for facsimile image
Inventor: IDE HISASHI
IPC: H04N1/21
Filed: 1989-11-27
Abstract: PURPOSE:To enable recording and reproducing at a constant speed even if the reception speed of a FAX(facsimile) image signal is changed and to simplify a recording and reproducing circuit by providing a dummy line output part, a dummy line deletion part, etc. CONSTITUTION:A data recording means 9 in a control part 7 records data on a storage medium 3 at a constant speed faster than the maximum reception speed of the FAX image signal. In recording, a dummy signal is recorded on the medium 3 through a dummy line output part 2 from the end of the recording of one line data to the end of the reception of next line data when the end of the recording of one line data of the received FAX image signal is ealier than the end of the reception of next line data. In reproduction, the data are reproduced at the same speed as the recording speed and the dummy signal is deleted from the data reproduced from the medium 3 through the dummy line deletion part 4. Therefore, even if the reception speed of the FAX image signal is varied, the recording and reproduction are performed at the constant speed and the processing is made efficient to simplify the recording and reproducing circuit.

Title: Sealed lead-acid storage battery
Inventor: ODA SANEHIRO
IPC: H01M2/02
Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To restrain escaping of water of electrolyte in the form of vapor through a jar of a storage battery by using polyphenylene ether material whose water vapor transmission coefficient is small as the material of jar, and using a material excellent in its bonding characteristic as the marial of a cover. SOLUTION: As a material of jar, polyphenylene ether(PPE) resin of a small water vapor transmission quantity whose water vapor transmission coefficient is 2.0g.mm/mm<2> .day.mmHg or less is used. As the material of a cover, ABS resin whose vapor transmission coefficient is relatively large is used in order to prevent decrease in the bonding strength of a terminal part. An adhesive is thickly applied to front and the rear surface of the cover to decrease the water vapor transmission from the cover. Accordingly, water of electrolyte escaping to the outside in the form of vapor from a jar and the cover can be reduced, thereby extending the service life.

Title: Production of metal bump and semiconductor device
Inventor: TOI YUTAKA
IPC: H05K3/10
Filed: 1993-11-12
Abstract: PURPOSE:To allow highly accurate formation of metal bumps in a short time through simple process by jetting conductive microparticles toward a terminal plane to form a deposition layer of the conductive microparticles bonded together and then fusing the deposition layer to form a metal bump. CONSTITUTION:When a metal bump 65 is formed on a predetermined terminal plane 62, conductive microparticles 38 are jetted toward the terminal plane 62 to form a deposition layer of the conductive microparticles bonded together and then the deposition layer is fused to form the metal bump 65. When the particles 38 are jetted toward the upper face of the package 61 for an integrated circuit, for example, the particles 38 bite the surface of exposed Al pad 62 at an opening where an elastic resist 63 is not formed and the particles 38 collide with each other at high speed and bonded thus growing a deposition layer of solder particles 38. After removing the elastic resist 63 under that state, it is placed in a furnace and heated. Consequently, the solder particles 38 are fused to form a spherical metal bump 65.

IPC: G01R22/00
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To equalize a load including that of general homes by integrating and displaying watt-hours at the measuring time in a set time zone. SOLUTION: A power arithmetic section 9 obtains the calculated value corresponding to the watt-hours consumed by a load 4 and inputs it to a central arithmetic section 12. The central arithmetic section 12 has a timing function for measuring time and integrates the watt-hours in the peak time zone set in a set section 13 as peak watt-hours, and it integrates the watt-hours in the normal time zone other than the peak time zone set in the set section 13 as normal watt-hours. The normal watt-hours and the peak watt-hours are converted into power charges and displayed on the normal charge time zone display section 15a and peak charge time zone display section 15b of a display unit 15. An alarm unit 14 is connected to the central arithmetic section 12. When the peak watt-hours exceed the basic watt-hours set in advance, the situation is reported via an alarm by sound or light.

Title: Horizontal position correction circuit
Inventor: OTSUJI MINORU
IPC: H04N3/227
Filed: 1988-12-06
Abstract: PURPOSE:To form an excellent picture without horizontal position dislocation by providing a DC feedback circuit between a flyback transformer and the time constant terminal of a horizontal oscillation circuit. CONSTITUTION:One terminal of a resistor R14 is connected to a high voltage winding negative terminal 28 in a DC negative feedback circuit and the other terminal is connected to the center terminal of a variable resistor R11. A negative voltage proportional to a beam current caused across the high winding negative terminal 28 connecting to the resistor R14 is applied to the horizontal oscillator time constant terminal 29 when the beam current is increased. That is, the fluctuation of the horizontal oscillating frequency caused by the phase distortion of a horizontal pulse due to the increase in the beam current is neutralized by applying the negative voltage proportional to the beam current through the proper selection of the resistance to the resistor R14 so as to keep the oscillating frequency constant. Thus, the dislocation in the horizontal center is prevented and an excellent pattern is obtained.

Filed: 1993-12-09
Abstract: PURPOSE:To enable lowering of noise and to prevent lessening of the quantity of outdoor air due to a place of installation of a product by a method wherein a cross flow fan is used for the indoor side and a one-side suction-exhaust structure for sucking and exhausting air only on the rear side of the main body of an air conditioner is provided for the outdoor side. CONSTITUTION:Air on the indoor side sucked from a direction (a) by the rotation of an indoor-side cross flow fan 25 is let out in a direction (b) through an indoor-side heat exchanger 26. Air on the outdoor side sucked from a direction (c) by the drive of a sirocco fan 29 is let out in a direction (d) through an outdoor-side heat exchanger 27. Herein the sirocco fan 29 used for sending the air on the outdoor side, which is disposed inside the main body 20 of an air conditioner, may have a large diameter due to the depth dimension having a relatively large allowance and thereby the height H of an outlet on the outdoor side can be made small. Thereby a large area can be ensured for an outdoor-air inlet part on the rear side, the area of the inlet side of the outdoor- side heat exchanger 27 can be enlarged, moreover, by forming it in the shape of L, and thus a necessary amount of heat exchange can be ensured.
