Title: Ultrasonic welding method and device thereof
Inventor: TAKAHASHI KIYOHIKO
IPC: B29C65/08
Filed: 1984-06-15
Abstract: PURPOSE:To weld plane plates mutually and positively, and to obtain a material to be welded, flatness thereof is the same as one before welding and which has high accuracy and high quality, by intruding a small projection to the superposing section of the material to be welded while vibrational energy is concentrated to the small projection and correcting strain generated in the surface by the flat end surface of a horn. CONSTITUTION:When the end surface 2 of a horn 1 is positioned vertically to the superposing sections of materials to be welded 4, 5, small projections 3 on the end surface 2 are pressed downward while being given vibrational energy and the small projections 3 are intruded to the upper surface of the material to be welded 4, frictional heat is generated in the materials to be welded 4, 5, and the materials to be welded are melted. The strain 7 of the material to be welded 4 protrudes around the intrusions of the small projections 3, but strain 7 is corrected by the end surface 2 of the horn when the horn 1 is further pressed and the end surface 2 is contact-bonded to the upper surface of the material to be welded 4, and the small projections 3 penetrate the joint surfaces 6 of the materials to be welded 4, 5, thus completely welding both the materials to be welded 4, 5. Clearances formed through an inflow between the materials to be welded 4, 5 of volume corresponding to the small projections 3 at that time can be removed according to the conditions of welding. After welding is completed, the small projections 3 are pulled out.

Abstract: PURPOSE:To realize high gm and low capacitance simultaneously by isolating a substrate and an active layer by an insulating film and forming structure in which a lower gate is shaped selectively only just under an upper gate in a junction gate type field-effect transistor (J-FET). CONSTITUTION:In the J-FET such as an N channel type J-FET, the insulating film 42 (such as a SiO2 film) is shaped onto the P type substrate 41, the insulating film of a section functioning as a lower gate region is removed selectively, a  P<+> type semiconductor layer 43 is formed to the whole surface by using a method such as an epitaxial method, and the unnecessary P<+> type layer 43 is removed through polishing and smoothed. It is preferable that a P<+> type layer 44 is selectively left only in one part of the insulating film at that time. An N type semiconductor layer 45 is grown onto the whole surface, a P<+> type gate region 47 is shaped onto the P<+> layer 44 through the known manufacture of the J-FET, and  a source region 48 and a drain region 49 are formed. The J- FET having high gm and low capacitance is obtained because the lower gate region is molded only just under the upper gate region and the substrate and the active layer are isolated by the insulating film.

Title: Wafer supporting and pushing apparatus in ion implantation
Inventor: NISHIMURA TADASHI
IPC: H01L21/677
Filed: 1979-09-25
Abstract: PURPOSE:To smoothly send out wafers by rotating a support member downward, contacting said member to a contact portion, rotating a pushing member, and giving an initail sliding velocity to the wafer by the pushing portion. CONSTITUTION:A wafer 41 that is put in a pre-exhausting chamber is received and supported by a supporting member 51 which is standing-by at a portion A. Then, the member 51 is rotated to a position B, and the wafer 41 is subjected to the ion implantation. When the implantation has been finished, the member 51 is rotated to a position C. When the member 51 approaches the position C, the lower portion of the member 51 contacts with a contact portion 53b of a pushing member 53, thereby the member 53 is rotated. A puhsing wheel 33 is pushed by a pushing portion 53a, thereby very small initial velocity is given. The pusing action of the pushing portion 53a does not give abrupt acceleration to the wafer 41 which is characterized by the normal movement, but gives only slight initial velocity at the initial period of sliding. Therefore, the cracks are seldom generated in the wafer 41 in a processing tank.

Title: Optical beam scanning device
Inventor: HONGOU JINICHI
IPC: G02B26/12
Filed: 1983-07-08
Abstract: PURPOSE:To improve scanning accuracy by controlling the optical quantity of a reflected beam in response to the incident angle of a light beam so as to compensate the luminous amount of the reflected beam changed in response to the change in the incident angle of the light beam to a polarizing device. CONSTITUTION:A bias current I1 is set to a maximum value at the same time when the laser lighting period for light beam position detection is started. A constant current source 107 is applied with feedback control by a photodetector PD and an optical output control circuit 105 so that the light output of a laser diode LD attains a prescribed value in this state. When the laser beam is inputted to a photodetector 300, a synchronizing signal S2 is generated, then the current I2 by the feedback control of the constant current source 107 is fixed. Since the counter subtraction of the circuit 105 is started in this case, the current I1 is decreased and the light output of the diode LD is also decreased. On the contrary, since the reflectance is made large because of the increased incident angle of the light beam to a rotary polygon mirror (not shown), the luminous intensity of the laser beam reflected from the rotary polygon mirror is unchanged.
