Patent JP-H03108372-A (JP)
Title: Semiconductor device
Inventor: NAKANO HIROAKI
IPC: H01L29/68
Filed: 1989-09-21
Abstract: PURPOSE:In a memory cell wherein reverse base currents are used, to enable base currents to be let flow even at low voltage by setting the concentration of the collector of a bipolar transistor to the specific value or more. CONSTITUTION:In an NPN bipolar transistor Tr11, when the voltage VCE between a collector and an emitter becomes large to some degree, reverse base currents are observed. And if the impurity concentration of the collector is 1.3X10<17>cm<-3> or higher, the reverse base currents are observed at 5V or lower voltage VCE. Accordingly, this Tr11 can be operated with a single power of 5V. In this case, the base impurity concentration is set to 3.9X10<18>cm<-3> or lower, and the emitter concentration is set to 4.2X10<20>cm<-3> or higher. The base concentration and the emitter concentration don't affect the voltage V so much as the collector concentration.

Title: Thermal transfer sheet
Inventor: USUKI HIDEKI
IPC: B41J31/00
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To enable fine transfer images to form with a stable and superior separation property with the transferred body by allowing a dye layer to contain at least sublimating dyes, a binder resin and a phosphoric esters. SOLUTION: The thermal transfer sheet is comprised of providing a dye layer 3 having at least one or more colors on one surface of the foundation sheet 2. The dye layer 3 is formed by adding sublimating dye, a binder resin, a phosphoric ester, and other arbitrary components in an appropriate solvent, dissolving and dispersing each component, and applying and drying them on the base sheet 2 by a forming method such as a gravure printing method. For example, when each yellow and magenta dye layer 3Y, 3M is a single layer structure and each cyan and black dye layer 3C, 3BK is a two layer structure, only the base sheet 2 side is contained with the phosphoric ester, the uppermost surface layer need not contain it because the phosphoric ester in the lower layer bleeds to the uppermost surface. When the dye layer 2 is a double layer, the content of the phosphoric ester can be varied in each layer.

Polling interval is varied for each mobile station based on the moving speed thereof such that the polling is performed at a short interval for a mobile station moving at high speed while performed at a long interval for a mobile station moving at low speed. According to the arrangement, the real time position indicating performance is enhanced for a mobile station moving at high speed and the number of times of polling can be decreased for a mobile station moving at low speed or stopping.

Abstract: PURPOSE:To sense compete tear-off of a sheet and to back feed it by providing at least two sheet detecting sensors for detecting both side ends of the sheet at a sheet discharge unit of a tear-off cutter. CONSTITUTION:Photoelectric sensors 2a, 2b are so arranged at both side ends of a sheet immediately after a sheet discharge unit 1a as to be opposed to one another. When a continuous sheet after printing is moved to the unit 1a, the sensors 2a, 2b detect presence of the sheet. Accordingly, a controller of a printer verifies output of signals of 'presence of a sheet' from both the sensors 2a, 2b, and continues a printing operation. When the continuous sheet 5 is drawn to be torn by a tear-off cutter 1 by an operator after the printing is finished, the controller takes AND condition of a change from the 'presence of the sheet' to 'absence of sheet' of both the sensors 2a, 2b, and judges the absence of the sheet.
