Title: Printer
IPC: B41J13/10
Filed: 1992-04-03
Abstract: PURPOSE:To contrive miniaturization of a printer body by a method wherein a paper guide of continuous paper fed from a tractor unit of a printer is formed by the tractor unit. CONSTITUTION:Since a paper guide 21c of continuous paper 3 fed with a tractor unit 20 is formed by the tractor unit 20 in this printer, the printer body 10 can be achieved to be miniaturized. Further, since a paper guide 20 is formed by the tractor unit 20 body, positional error between a tractor 22 and the paper guide 21c is not generated, or if generated, it is very little. Therefore, an inlet 23 of a paper guide part can be made small by shortening paper guides 10c and 21c on the body side and on the tractor unit side, and the whole of the printer under a state wherein the tractor unit is attached thereto can be achieved to be miniaturized.

Title: Radiation detecting device
Inventor: MATSUOKA TAKESHI
IPC: G01T1/24
Filed: 1989-03-31
Abstract: PURPOSE:To measure radiation with high efficiency and a small counting error without using any thick detector material by absorbing the radiation to be detected by detectors in partial charge which are arrayed in series in its incidence direction. CONSTITUTION:The detectors 1 and 11 are arranged, the detector 11 of a final state is formed of CaTe, and the detector 1 which is formed of a semiconductor GaAs with a larger carrier migration extent than CaTe is provided in front of the detector 11. Then, about 50% of the radiation R is absorbed by the detector 1 first and a little bit larger 90% of the remaining almost 50% of the radiation is absorbed by the detector 11 when the thickness of the detectors 1 and 11 is, for example, 0.4mm and the energy of the radiation R to be detected is 50keV. Therefore, the number of radiation photons which are actually incident decreases to half on the detector 11 and the generation of a pile-up is decreased as compared with a case wherein only the detector 11 is used, so that the detector 1 may be thick enough to absorb a part of the radiation R to be detected. Further, the whole device can detect the radiation R with 95% efficiency without any counting error.

Title: Controller for electromagnetic linear motor
Inventor: YAKOBU GIRUGEN
IPC: H02P27/02
Filed: 1986-04-11
Abstract: A control apparatus for a linear motor, having main and auxiliary driving coils and which drives a movable plate is disclosed. The control apparatus, which determines if the plate is within an active area of the motor and, if so, supplies current to the coils, includes an alarm circuit for generating a first measuring signal dependent on the current flowing through the main coil and a second measuring signal dependent on the current flowing through the auxiliary coil. The phase relation between the two measuring signals changes depending on whether the plate is within the active area of the linear motor or not. The alarm circuit senses the measuring signals and generates a switch signal at a first output and an engaged signal at a second output if the plate is within the active area of the linear motor. The switch signal is coupled to an adjustable delay circuit which transmits the delayed switch signal to a switching circuit to actuate a switching medium connected in series with the linear motor. The delay circuit has another input for an engaged signal generated by another control apparatus and, if such an engaged signal is present, the transmission of the switch signal to the switching circuit is prevented.

IPC: F02M51/08
Filed: 1979-06-29
Abstract: PURPOSE: To make a motion of a valve quicker while to plan to improve an accuracy of amount of flow by preventing a standing pressure wave by a method wherein fuel is fed through a fuel feeding hole provied near a valve seat, and a hole releasing the pressure wave from a back pressure side of the valve is provided so as to face the feeding hole.  
     CONSTITUTION: A valve 1 is guided by a valve sliding portion 1c, however, when the valve 1 is moved in high speed, a pressure wave is generated in a back pressure chamber 11 and is returned to a fuel feeding portion 5 through a back pressure hole 7. That means, when the valve 1 is sucked, a positive pressure wave is generated in the back pressure chamber 11 and increases a pressure in the feeding portion 5, therby, promotes an injection of fuel from a feeding hole 6, however, on the contrarry, when the valve 1 is closed, a negative pressure wave is applied on the feeding portion 5 from the back pressure chamber 11 and acts to stop the fuel. As described above, the pressure wave acts to help a motion of the fuel flowing from the feeding hole 6 at a proximity of the feeding portion 5 while the pressure wave is not delivered to a distant place within a pipe of feeding system, therefore, a standing wave is hardly generated within the pipe.

Abstract: PURPOSE:To enable the frequency division of the >=100MHz high frequencies signal, by connecting the input and output terminals of the inverter circuit to each of two terminals of the transfer gate circuit. CONSTITUTION:When the potential at the input and output terminals A, B of the inverter circuit 12 is respectively at high and low level, and when the clock signal phi is at low level and the transfer gate circuit 11 is nonconductive, if the signal phi is changed to high level, the potential at the point A is changed to low level after the specified time delay, because of the conduction of the circuit 11.
