Abstract: PURPOSE:To make it possible to reduce the capacity of a character pattern memory and to enhance the speed of conversion of a character into a dot pattern, by a system wherein when simultaneously printing image data and character data, the character data are converted into dot patterns with a low dot density. CONSTITUTION:Character data and image data on graphics or the like from a host device (a) are received by an interface-controlling part 1. Of the data thus received, the character data are supplied from the part 1 to a character-dot converting part 4, by which character patterns to be printed are converted into dot patterns by using character patterns stored in a character pattern memory 5 connected to the converting part 4, and the dot patterns are sent to a character dot page memory 6. The ratio of dot density in the memory 6 to that in a printing part 9 in terms of side ratio is set to be 1/n (n is an integer), both vertically and horizontally. Output dot signals from the memory 6 to become printing dot data are inputted to an enlarging circuit 7 for obtaining dot patterns which are (n) times as large as the original dot patterns, in terms of vertical and horizontal side ratios. An output from the circuit 7 is ORed with an output from a graphic dot page memory 3 by an OR circuit 8, and the OR thus obtained is sent to the printing part 9, thereby printing.

Title: Identification system
Inventor: HENRIIESU KATSUTSUENSUTAIN
IPC: G06K19/06
Filed: 1987-03-14
Abstract: A reader identifies information, such as the identity of an object at a transponder, provided in binary form by the transponder. The reader initially generates a pulse which activates the transponder into transmitting a series of signals, such as by magnetic induction, to the reader. Upon each count of a particular number of signals in the reader, the reader generates an additional pulse which causes the transponder to transmit a new series of signals to the reader. The generation of the pulses by the reader may occur through the charge and discharge of energy in a storage member such as a capacitance. The series of signals produced by the transponder may have either a first frequency or a second frequency. The signals may be generated in each sequence at the first and second frequencies in an order dependent upon (a) the binary code identifying the object at the transponder and (b) the polarity of the pulse produced by the transponder in such sequence. The signals may be generated at the second frequency by connecting a capacitance across a coupling coil at the transponder. The reader then identifies the information by demodulating the signals received by it at the first and second frequencies. The reader is able to interrupt at any time the generation of the sequences of signals at the transponder when it does not receive the signals transmitted by the transponder. The reader then operates on a free running basis to generate pulses of opposite polarity at a relatively low frequency. In this way, the reader is constantly prepared to activate the transponder when the transponder becomes subsequently disposed within the effective range of the reader.

Title: Ion implanter
Inventor: YAMAGUCHI KAZUO
IPC: H01L21/265
Filed: 1988-03-14
Abstract: PURPOSE:To neutralize positive electric charges remaining on the surface of a semiconductor wafer effectively by furnishing a magnetic field generating source on a wafer disc, and by forming a line of magnetic force on the surface of semiconductor wafer fixed onto the wafer disc. CONSTITUTION:A magnetic field generating source, for ex. a rod-shaped magnet 5, is installed on a holder 2 of a wafer disc 1. A positive ion 3a which has attained a wafer W intrudes into it, and positive electric charges 7 remain at this time on the surface Wa. An electron 4a, on the other hand, which has attained the wafer W together with the positive ion 3a moves on the surface Wa, but because a line of magnetic force 6 is formed on the surface Wa, the electron 4a makes cycloid motion in either direction depending upon the motion vector at the time of attainment to move in the direction across even the line of magnetic force 6. During this motion, the electron 4a collides with the positive electric charge 7 to neutralize it. This increases provability of collision of electron 4a with positive electric charge 7, and the residual positive electric charges 7 are neutralized effectively.

Title: Multi-stage double casing type fluid machine
Inventor: MISUMI YOJI
IPC: F04D29/42
Filed: 1985-03-25
Abstract: PURPOSE:To shorten time necessary for warming by reducing a space between inner and outer casings and providing a passage through which fluid for warming flows stepwise successively so that the flow rate of the fluid increases to increase heat transfer coefficient to the outer casing. CONSTITUTION:Fluid for warming which enters through a warming fluid inlet 7 flows through a narrow space 10 between inner and outer casings 3, 1 in the direction shown by an arrow without separating in the right and left directions. The fluid which reaches a rail 8 is introduced into a next stage through a notched portion 12 to flow in the opposite direction, then the fluid is further introduced into a next stage through a notched portion 12 provided in the same manner. To permit such a flow of the fluid the inner casing 3 has projections 11 disposed at its outer periphery and the notched portion 12 is disposed at the side of the rail 8. Since heat transfer coefficient of fluid to a solid increases in proportion to a flow rate of the fluid to the 0.8th power, an increase in the flow rate of the fluid by such an arrangement permits an increase in its heat transfer coefficient to the outer casing 1 which has the least warming capability and a reduction in warming time.

Abstract: PURPOSE:To make a wafer extruder cope easily with the increase of the diameter of a wafer, and to ensure even positioning accuracy extremely easily by utilizing a long-sized member, to which a bendable and attitude restoring inclination is imparted, as a wafer extruding member by a specific method. CONSTITUTION:A wafer extruding member 11 is formed by a member, to which a bendable and attitude restoring inclination is given, and the extruding member 11 is direction-changed in an intermediate section by a guide apparatus 12 so that the nose side proceeding to and retreating from the wafer-housing cassette 1 can be moved in the horizontal direction and the base end side in the vertical direction. Consequently, even when the diameter of a wafer 2 is increased, pull-in size in the vertical direction of the wafer may only the considered, and device size in the horizontal direction as an extruder need may not be considered. That is, the constitution of the wafer extruding member 11 has no effect in a spatial dimensional manner. Since the extruding member 11 is provided with the attitude restoring inclination by a convex shape, it is not buckled and a nose thereof does not hang down under its own weight even when the nose proceeds up to the longest position, thus positively extruding the light-weight wafer 2.
