Title: Molding of roots type pump rotor
Inventor: KOHAMA TADAHIKO
IPC: F04C18/08
Filed: 1986-11-05
Abstract: PURPOSE:To prevent exfoliation of a resin layer by covering an insert member made of aluminium alloy with a resin layer made of the liquid crystal polyester resin or the composition thereof through injection molding. CONSTITUTION:The surface of an insert member 6 which is made of aluminium alloy and has a cocoon-shaped outer shape is covered with the resin composition consisting of liquid crystal aromatic polyester resin, graphite, fluorinated resin through injection molding. Since, with such constitution, the volume contraction rate in the coagulation from molten state of the resin composition is small and the difference of the thermal expansion rate from aluminium alloy is small and the resin composition intrudes into the uneven part on the surface of the insert member 6, a Roots type pump rotor 1 in which the resin layer is not exfoliated even after the use for a long period can be obtained.

Title: Longitudinal field effect transistor
Inventor: SHIDA NAOYUKI
IPC: H01L29/78
Filed: 1992-10-01
Abstract: PURPOSE:To avoid the increase in on-resistance even if the specific resistance in an epitaxial layer is increased for increasing the breakdown voltage between source and drain in the conventional field effect transistor. CONSTITUTION:In the longitudinal field effect transistor, a high concentration region 3 is provided between base regions 4 separated from each other. Besides, the impurity concentration in the high concentration region 3 is set up to be higher than that in an epitaxial layer 2.

Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To execute change-over into an optimum idle channel during a call by providing a fourth step or the like, by which the idle channel having the second best value is detected in a candidate list of a radio line quality table and it is set to a frequency channel to be used in voice communication.

In S15, an RSSI signal level is inspected, based on a measurement result by a reception level measuring circuit. Then in S16, order in the candidate list of the radio line quality table is changed based on the RSSI signal level. Then the channel is changed-over into the original frequency channel which is used for a voice call in S17. Thus, the frequency channels are changed-over so that movement is executed to the optimum idle channel during the call.

Title: Joined body by brazing
Inventor: MARUYAMA MIHO
IPC: B23K1/20
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To inhibit crack growth or instant fracture in the joined body from being caused when the joined body is cooled after the joining by forming recessed parts each having specified dimensions in a surface to be joined of the ceramic material, at the time of manufacturing a ceramic/metal joined body by joining a ceramic material and a metallic object to be joined, such as sealing metallic fixture, together through brazing. SOLUTION: In the manufacture of this joined body, recessed parts each having a 5 to 80 μm width are formed in a surface to be joined by brazing of a ceramic material, wherein the width of each of the recessed parts is desirably 0.7 to 5 times as long as its depth and also, 0.05 to 0.3 times as long as the space between every adjacent two of the recessed parts. In each of these recessed parts, a metallic phase which consists of a Ti segregation layer and an Ag-Cu alloy and is used for joining the ceramic material and a metallic object to be joined, is formed. When the ceramic material is alumina, this metallic phase also contains Al that is a reduction product, and accordingly, is chemically bonded to the ceramic material.  In the cooling process after the joining, a compression stress field is formed in the joined metallic object and accordingly, residual stress is caused in the joined surface of the ceramic material to generate cracks in this surface. However, growth of the cracks is hindered by the recessed parts to prevent the slow crack growth or instant fracture from being caused and to obtain the objective joined body having good properties. The recessed parts are formed by a grinding method, or the like.

IPC: B65G61/00
Filed: 1992-10-02
Abstract: PURPOSE:To accurately obtain the operation record of a vehicle by small manhour without assistance by receiving a radio wave radiated from a satellite and recording measured positional information correspondingly to the time information. CONSTITUTION:A GAS receiving part 2 receives a radio wave from an artificial satellite for GPS use and outputs a positional information to a recording circuit 3.

Consequently the lack of positional information for a period of time during which radio waves from the satellite can not be received during the travelling period of traveling in a tunnel or the like can be removed. Various information recorded in a memory of the circuit 3 is copied in a floppy disk or an IC card, and when the preceding record exists in the disk or the card, a cotinued recording position is retrieved and a power supply for the device is turned off.

Abstract: PURPOSE:To attain excellent picture reading by providing a white level section obtaining a density data equal to a white level for several levels from the white level to a table of a density conversion circuit so as to prevent picture quality deterioration such as fog or jump of a read picture. CONSTITUTION:A shading correction means (b) decide a white level based on a signal obtained by applying photoelectric conversion to a reflected light from a white board for white level adjustment by an original scanning system (a) and a signal value being the result of photoelectric-converting the reflected light from white paper corresponding to the white level of the original. In converting a signal value proportional to the reflected luminous quantity of the original into the density value, density converting means (c) uses the prescribed several levels from the white level decided by the shading correction means (b) as the white level section and converts the level to the density equal to that of the white level at all time. Fog or jump of the picture is prevented in the white level section. For example, the level is set between an 8th level and a 40th level. Thus, the occurrence of picture quality deterioration such as fog or picture jump is prevented and excellent picture reading is attained.
