Patent JP-H02272793-A (JP)
Title: Manufacture of metallic base printed wiring board
Inventor: SATO SUKEHISA
IPC: H05K3/44
Filed: 1989-04-14
Abstract: PURPOSE:To eliminate the insulating failure and disconnection of a circuit by effecting a process for manufacturing a flexible printed wiring board and a process for molding a metallic base separately. CONSTITUTION:A copper foil 2 as a circuit conductor is bonded onto a non- or semi- cured flexible substrate 3 composed of a glass cloth base and an epoxy resin base. A circuit is formed on a flexible printed wiring board 1 by a printing wiring technique. If the wiring board 1 bumps or touches during a process such as etching, the disconnection of a circuit and an insulating failure does not occur because the wiring board 1 is light. A metallic base 4 is subjected to a bending or drawing process by using a die and the wiring board 1 is bonded with its inside or outside by heat pressing. For facilitating the attachment, slits or cutouts 5 are formed. The heat-pressing bonding cures the substrate 3, but the substrate does not lose its flexibility because it is thin. By the secondary effect of the heat-pressing bonding, a conductor part composed of the copper foil 2 of the wiring board 1 is buried in the substrate 3, so that the contact with other electronic parts in a narrow space can be prevented. Thus, a contact accident, the disconnection of circuit during a drawing or bending process, or an insulating failure due to a flaw of an insulating part or peeling can be eliminated.

Title: Method and device for transporting sheet
Inventor: ISHIKAWA MASAAKI
IPC: B65H5/06
Filed: 1985-04-30
Abstract: PURPOSE:To provide sheet transport at two slightly different speeds by operating either of the two drive rollers with different linear speeds at the peripheries and by keeping the other drive roller in idling. CONSTITUTION:When a step motor 7 is rotated in the D direction, the drive shaft 3 rotates in B direction, and a drive roller 1 will rotate in the B direction through the action of a one-way clutch 10 which can transmit the torque only in the B direction. As another one-way clutch 11 transmits the torque only in C direction, no torque is transmitted to a drive roller 2. Therefore, a sheet on the sheet transport path A is transported in F direction at the same speed as the peripheral speed of the drive roller 1. If on the other hand the motor 7 is rotated reversely at the same speed, the sheet is transported in the F direction at the same speed as the peripheral speed of the drive roller 2. Because the outside dia. of the roller 2 is greater than that of the roller 1, it can easily be accomplish to run the sheet at two slightly different speeds through optimum selection of operation of such a reversible motor 7.

Title: Heat to kinetic energy converting device
Inventor: YASUDA YOUICHI
IPC: F01K25/04
Filed: 1980-07-10
Abstract: PURPOSE: To convert minor thermal energy into kinetic energy using a device which is to obtain it with a low boiling point liquid by accomodating the liquid in two containers, upper and lower, and making use of the rising flow generated when the lower container is heated.  
     CONSTITUTION: A container 5 installed below another container 2 with water wheel 1 is filled with low boiling point liquid consisting of methylene chloride to  form a lower liquid 7. Another liquid 8 having a specific gravity smaller than the  lower liquid 7 is added to the container 2 so that the liquid level will be at a certain  point in a liquid flow receptable 1" of the water wheel 1. When heated into boiling,  the liquid 7 is throttled at the upper end 5" and collides against the receptacle 1" to  give the rotary motive to the water wheel 1, where the temperature of upper liquid  8 is adjusted so as to regulate the rising flow of vaporized liquid 7 into a constant  rate and drive the wheel 1 constantly, and further the gasified methylene chroyide  expands in the upper part of container 2 to heave a piston 3 and drive it. Thus  minor thermal energy can be converted into kinetic energy with good efficiency.

Title: Solar heat pump device
Inventor: OOTSUKA NOBUO
IPC: F24S90/00
Filed: 1983-05-27
Abstract: PURPOSE:To collect the solar heat with a small electrical input by supplying the refrigerant from a condenser to a solar heat collector when the sunlight is sufficient by means of a switch valve that switches a compressor into a liquid pump. CONSTITUTION:When there is no sunlight or the sunlight is weak, a normal heat pump mode is used. (Solid line arrow) When there is adequate sunlight, a four- way valve 12 is switched and an expansion valve is fully opened. By this, the refrigerant liquefied by a condenser 2 is supplied to a solar heat collector 4 by a compressor 13 which can also be used as a liquid pump by being regulated its rotational speed. The refrigerant is vaporized there, and passes through the expansion valve 14 to return to the condenser 2 again to be liquefied. (Broken line arrow) At this time, the temperature and pressure of the solar heat collector 4 and condenser 2 become nearly equal. Since the compressor 13 is also used as a liquid pump, the rotational speed is lowered as much as possible, and the power consumption is reduced, so that the delivery capacity may not become excessive.

Title: Pen input device
Inventor: HIRANO KATSUMI
IPC: G06F3/0488
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To discriminate a correct detection mode without being affected by a noise from a backlight by discriminating the approach of a detecting pen by comparing a value, for which a voltage induced by the detecting pen is converted to a DC voltage, with a threshold value set in advance. SOLUTION: The voltage induced by the top end electrode of a detecting pen 3 is sampled with a gate signal generated by a gate signal generating circuit 7 by an analog gate circuit 11a and at a sample/hold circuit 11b, a spike-shaped voltage is converted to the DC voltage. A comparator circuit 14 compares this DC voltage with a voltage set by a threshold value setting circuit 13. When the voltage of the signal sampled by the gate signal is higher as a result of comparison, a mode signal becomes 'H' and it is discriminated that the detecting pen 3 gets sufficiently closer to a liquid crystal panel 1. Then, when the mode signal is 'H', a coordinate signal is regarded valid so that only the correct coordinate is detected.

Abstract: PURPOSE:To facilitate effective contraction and expansion of lithograph data and improve the utilization factor of a lithography apparatus and a lithograph throughput by a method wherein pattern data, arrangement data and dosage data which are contained in lithograph data are separated from each other and a lithograph region is divided into necessary small regions and the dosages for the respective small regions are predetermined. CONSTITUTION:A group of arrangement data (1), a group of pattern data (2) and a group of dosage data (3) which are contained in lithograph data are described in the lithograph data storage memory of a lithograph control circuit and they are separated from each other. In accordance with the data groups, the pattern data are divided into respective regions which have necessary shapes and are smaller than the spread area of the back scattering of a charged particle beam. The representing points of respective lithograph unit patterns are calculated and an electron beam dosage for one unit pattern is obtained and predetermined in accordance with the control data of the region corresponding to the representing point of that unit pattern. With this constitution, effective contraction and expansion of the lithograph data are facilitated even if the lithograph is performed while the dosage is varied in order to correct a proximity effect and the utilization of a lithograph apparatus and a lithograph throughput can be improved.
