Title: Method of making semiconductor device
Inventor: NAKASHIMA TATSUNORI
IPC: H01L21/58
Filed: 1978-07-07
Abstract: PURPOSE: To improve the characteristics such as the serial electric resistance of a gate, noise voltage, etc. by previously implanting the same conductivity type of impurity ions as that of a semiconductor chip substrate into a metal foil upon joining the substrate through the metal foil with a header by a eutectic technique.  
     CONSTITUTION: Joining a semiconductor chip substrate through a metal foil with a header, boron ions for the p-type substrate, and phosphorus, antimony or arsenic ions for the n-type substrate are implanted respectively. For example, using a p-type silicon substrate 2, the epitaxial growth of a n-type layer 3 is first allowed to proceed thereon to form the insular layer 3 surrounded by a p-type region 2'. Then, a p-type gate 4, a n-type source 5, and a drain region 6 are provided in the layer 3. The semiconductor chip 1 made in this way is joined through a metal foil 7 to the layer 11 of the header 9 comprising Kovar 10 and gold plated layers 11. Thereupon, if a boron ion implanted layer 8 is provided to the metal foil 7, the characteristics such as g m , etc. are improved and incidental effects may be reduced.

Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To easily correct the deviation of printed dots in multi-transferring by reading a reference pattern formed on a sheet and switching the rotational speed of a carrying roller, based on the deviation of the printed dots. SOLUTION: When a reference pattern detection mode switch is turned on, the reference pattern is read by an image reader unit and color slurring between a cyan pattern and a magenta pattern is measured.

IPC: B29C43/02
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To increase a strength by reheating so that a surface temperature of a foamable resin base material and its inner temperature respectively become specific temperatures, and press molding it, thereby obtaining a plate thickness without collapsing the generated foams. SOLUTION: In a first heating step, an azodicarbonamide of a foaming agent of a foamable resin base material 16 containing a polypropylene as a main component is foamed to a resin foam 18. This foam 18 is conveyed into heating furnaces 22, 22' in a second heating step, heated to, for example, 200 deg.C in the upper furnace 22, and 150 deg.C in the lower furnace 22'. Thus, a temperature of a surface of the foam 18 conveyed in a next molding step is 180 to 200 deg.C, i.e., a temperature for starting foaming from the temperature arriving at the melting point, and its inner temperature is 150 to 180οC, i.e., a temperature arriving the melting point from a temperature arriving at a softening point of a synthetic resin. As described above, the foam 18 is reheated in the second heating step to become a temperature range of 180 to 200 deg.C, and press molded in this temperature range.

Filed: 1980-06-23
Abstract: PURPOSE:To eliminate the waste of high pressure injection fluid and to prevent the abrasion of peripheral apparatus by changing the injection width of a header by the movement of the header body in its longitudinal direction. CONSTITUTION:In the case of removing the scale of a rolling material 40 of the smallest width, it is a nozzle 21b which is in alignment to the center C of the line, and a rotary valve 29A is held closed, 29B held opened and 29C held opened. Namely, the nozzles which are injecting fluid are the three pieces of 21a, 21b, 21c. Then, in the case of adapting this to a rolling material 41 of further greater width, a header body 20 is slided by the nozzle pitch. A pinion meshing with a rack rotates 90 deg., and the rotary valve 29A opens, 29B closes and 29C opens, so that highly pressurized water is filled in chambers 23, 24, and the highly pressurized water is injected only from five pieces of the injection nozzles 21a-21e. Thus, the injection width is changed arbitrarily for any width of the rolling materials simply by sliding the head body axially.

Filed: 1984-04-26
Abstract: PURPOSE:To increase the printing speed of a printing head by almost eliminating the rebounding of a movable part, by providing a damping mechanism having an inertia member impinging on the movable part when the movable part performs return operation. CONSTITUTION:The same number of leaf springs 21 as armatures 2 are formed and inertia members 23 are fixed to the leading ends of said leaf springs 21 to constitute a damping mechanism 71. The mechanism 71 is attached to the insulating member attached to a base 7. When the armatures 2 perform return operation, the leading ends of the armatures 2 impinge on the inertia members 23 and male screws 19a are regulated so that the impingement of said armatures 2 is performed immediately before the return of the armatures 2 to a stand-by position. Further, the equivalent of the damping mechanism 71 is made almost equal to that of the operation part of one set consisting of one set of an arm part 3 and one printing wire 6. Because of this, when the armatures 2 impinge to the inertia members 23, the armatures 2 are almost brought to a stationary state and the operation of the armatures 2 receives no effect of the elastical change of the damping mechanism 71 and a printing speed can be increased.

Title: Image communication device
Inventor: FURUKAWA NOBORU
IPC: H04N1/32
Filed: 1996-04-08
Abstract: PURPOSE: To easily acquire the management information on users by initializing a storage device to read out the storage contents through a storage controller when the storage control information reaches a prescribed value and then supply ing automatically the communication management information through an output device. CONSTITUTION: A CPU receives an ID code and stores it in a RAM 1 together with the next opposite party No. (ID) and a transmission/reception discrimination code. Then the CPU stores a start time discrimination code in a RAM 2 and reads the start time out of a clock circuit IGC to store it in the RAM 2. When the transmission/reception is over, a system control SCU releases the circuit IGC and gives a code showing the end of the transmission/reception to the CPU together with the transmission/reception final page no. Then the CPU compares the record value data on the RAM 2 with a prescribed value and gives a print-out instruction to the SCU when the record value data are larger than the prescribed value. The SCU gives a print-out instruction to the CPU as long as a record system has no abnormality. Then the CPU reads the character codes out of the RAM 1 for each line and then prints them out.
