Title: Image forming device
Inventor: OKAZAWA KAZUHIKO
IPC: G03G15/00
Filed: 1994-05-30
Abstract: PURPOSE:To eliminate the slacking and tension of a transfer material and to prevent the elongation of an image and the scattering of toner by eliminating the carrying speed difference between a transfer drum and a fixing unit with respect to the transfer material. CONSTITUTION:The carrying speed V0 of the transfer material by the transfer drum 6 is obtained by the length of the transfer material, the speed of revolutions of the transfer drum 6, etc., and the carrying speed V1 of the transfer material by the fixing unit 8 is obtained by the length of the transfer material and the time of the passage of the transfer material on a paper ejection sensor 34 on the downstream side of the fixing unit 8. When a difference dV(=V0-V1) is made between both carrying speeds by the wearing of a fixing roller 8a, etc., a transfer material is slacked or tensed when the transfer paper is simultaneously carried by both of the transfer drum 6 and the fixing unit 8. The rotation of a motor 6A or 8A is controlled by a CPU 50 to eliminate the speed difference dV.

Abstract: PURPOSE:To allow a desired material to be deposited selectively in a contact hole by a method wherein an impurity-diffused layer opposite to a substrate in conductivity type is provided, a metal film is deposited on said impurity- diffused layer, and then the substrate is placed in an electrolytic solution and exposed to light. CONSTITUTION:A substrate 1 is placed in a water solution 11 of etectrolytic material including platinum ions, chlorine ions, and a supporting electrolyte (sodium sulfate), and is then exposed to a light beam 12 of a wavelength capable of exciting silicon. Under these conditions, charge separation takes place inside the semiconductor, for electrons 13 to collect at the bottom of a second contact hole 10 after travelling through an N-layer and Al-wiring and for holes 14 to collect at a substrate rear side (P-type region) 15. Electrons on the surface reduces platinum ions in the solution for platinum 16 deposited in the contact hole. Holes on the surface oxidize chlorine ions in the solution for the generation of chlorine gas on the substrate rear side 15, when nothing remains on the substrate rear side 15 because the resultant chlorine gas leaves the place where it is generated. Nothing is deposited on a second interlayer insulating film 9 because there is not any reaction taking place thereon.

Title: Portable telephone set
Inventor: KAWASHIMA KAZUYUKI
IPC: H04W76/02
Filed: 1995-05-15
Abstract: PURPOSE: To attain small size and light weight of the telephone set and to improve the operability at the arrival of a call by using a single motor so as to select the operation of a vibration call section and an operation of an antenna telescopic section. CONSTITUTION: When the portable telephone set 1 receives a call, a motor 10 is driven forward by a signal from a control section and a vibration generating section 20 is vibrated to inform the user of the arrival of the call. When the user slides an operation section 43 to the position of information, a power changeover section 40 rises to mesh a gear 11 of the motor 10 with a gear 31 of an antenna telescopic section 30 thereby setting the antenna in the telescopic state, opening a hook switch 50, and setting a hook-off state into a speech enable state. When the speech is finished, the switch is used to reverse the motor, the antenna is contracted. The operation section 43 is skided downward to allow a support section 41 to close the hook switch.  Thus, the single motor drives selectively the vibration generating section or the elongation/ contraction of the antenna through the operation of the power changeover section, thereby attaining small size, light weight of the telephone set and simplifying the configuration.
