Patent JP-H04354147-A (JP)
Title: Graphite jig
Inventor: HORIO TAISHIN
IPC: H01L23/02
Filed: 1991-05-30
Abstract: PURPOSE:To eliminate the occurrence of troubles of coming off or falling of a metallic pin so as to obtain a highly durable graphite jig by forming the positioning pin of the jig of a ceramic material. CONSTITUTION:The positioning pin of this graphite jig is formed of a ceramic material. While SiC, Si3N4, Al2O3, etc., can be used as the ceramic material, it is preferable to use a ceramic material the thermal expansion of which does not differ much from that of graphite. For example, a hole 3 for inserting an SiC pin 2 is formed through the jig main body 1 from the upper surface to the lower surface and a layer of a bonding agent 4 is formed on the part where the pin 2 is brought into contact with the hole 3. It is better to use a thermosetting bonding agent for sticking the pin 2 to the jig main body 1, because the jig is exposed to a high temperature. Thus the ceramic pin 2 can be stuck to the jig main body 1 with the bonding agent 4 after the pin 2 is inserted into the hole 3 and the coming off or falling of the ceramic pin can be prevented.

Title: Pneumatic spring for vehicle
Inventor: YAMAZAKI KIYOUJI
IPC: F16F9/04
Filed: 1978-12-15
Abstract: PURPOSE:To enhance durability and transverse displacibility by employing netting object of synthetic fiber. CONSTITUTION:Between metal plates or plastic plates 2 attached to the flexible member 1 and the undersurface plate 3, a netting object 4 of synthetic fiber 4 provided with rigidity through resin processing of such fibers with less down as heat  treated polyamid, polyester, binylon etc. shall be interposed. By this, a netting  pattern is produced when this synthetic fiber net 4 bites into the flexible member 1  at the undersurface plate 3, and the fiber in the net contacts directly the metal plate  or the plastic plate 2 while the flexible member's 1 contact with the metal or plastic plate 2 becomes indirect. And a slip will occur finally between the metal or plastic plate 2 and the synthetic fiber net 4, which reduces the friction coefficient as well as the spring constant of the pneumatic spring in the transverse direction.

Title: Semiconductor device
Inventor: SAITOU KOU
IPC: H01L23/36
Filed: 1980-11-07
Abstract: PURPOSE:To obtain sufficient heat resistance and cold resistance of a semiconductor device even when the device has a junction between materials of different type by providing holding means for forming an adequate solder layer between a radiating plate and an insulating plate and between the insulating plate and a semiconductor element. CONSTITUTION:An insulating plate such as a ceramic plate having a metallized layer 9a via a solder layer 8 is bonded on a heat radiating plate 7 formed with holding means made of projections 7a, 7b. Further, a large power semiconductor element 11 formed with projections 11a, 11b via a solder layer 10 is bonded thereon. Since the thickness of the solder layer can be specified by the holding means provided at the layer in the semiconductor device thus constructed, the solder layer of sufficient thickness can be obtained by selecting the thickness of the holding means. As a consequence, a semiconductor strong for the thermal change can be obtained. The shape of the holding means may not always be projections, but may also be any shape.

Accordingly, by glossiness of a resin layer 2, an irradiation light of a light source of a copying machine is reflected regularly by the surface of the resin layer 2, and a copy preventive function works. Also, when copy is executed to the sheet by a coloring processing, a copy character, etc., become easily readably, and on the other hand, a when copy is executed by using the sheet as a document, blackening of its copy is added to a copy action of the high glossiness resin layer 2 and enhanced. In such a way, copy can be prevented, and also, this sheet can be utilized as copy paper.

Title: Bipolar transistor
Inventor: ISHIBASHI TADAO
IPC: H01L29/205
Filed: 1990-06-16
Abstract: PURPOSE:To realize further speedup of a BCD by making electronic affinity in the interface forming heterojunction smaller than the electronic affinity of a collector electrode layer while setting-up electronic density of the collector electrode layer as occasion calls for. CONSTITUTION:By changing InAs composition of an InGaAs collector electrode layer in the interface, conduction band incontinuous DELTAEc in the interface between the collector layer 3 and the collector electrode layer 4 can be changed in the range from zero to about 1eV. The height of a potential-difference in level becomes controllable in the range large by selecting an electron density of the collector electrode layer to a desired value. An electrode density (n) of the collector electrode layer is given by n=NcF1/2(DELTAF/kT), and when, as an example, an electron density of the collector electrode layer (InAs composition 53%) is selected to n=5X10<18>/cm<3>, a Fermi-level DELTAF of electrons can obtain a sufficiently big value such as DELTAF=250meV so as to become an effective method for controlling the potential difference in level.

Filed: 1985-07-16
Abstract: PURPOSE:To form an ornamental layer having fine metallic luster by plating by successively forming an underlayer having a smooth surface and an electrically conductive layer on a nonconductive blank having a porous surface and by carrying out electroplating. CONSTITUTION:Paint is applied to a blank 1 having a porous or rough surface and made of an electric nonconductor such as wood or urethane foam to form an underlayer 2 having a smooth surface.

The layer 3 may be formed by carrying out conventional pretreatment for electroplating on ABS resin or the like. Desired electroplating such as gold plating, brass plating or Cr plating is then carried out on the layer 3 to form a layer 4 having metallic luster. Thus, the blank 1 can be ornamented by plating at a low cost.
