Filed: 1982-02-25
Abstract: PURPOSE:To match an external impedance and a impedance at the terminal of amplifier, by opening one end of a strip conductor connected to the terminal and connecting one end of a strip conductor placed in parallel to the specified terminal of the amplifier and the other end to a resistor and a capacitor for termination. CONSTITUTION:One end of a strip conductor 18 connected to a power supply is opened. One end of a strip conductor 19 in parallel with the conductor 18 is connected to an input terminal 2 of an FET amplifier 1, and the other end is terminated with a resistor 11 and a capacitor 12. Since the capacitance of the capacitor 12 is selected for the reactance so as to be almost zero at microwave band, the strip conductors 18, 19, a dielectric base 8 and a ground conductor 9 form a coupling line 20. This coupling line is a band pass filter and arbitrary characteristic impedance is selected by selecting the width and length of the strip conductors 18, 19 and the interval between the strip conductors suitably.

Filed: 1985-02-18
Abstract: PURPOSE:To cope successfully with both DPCM and chain coding systems by performing the sampling with the low sampling frequency of about 30Hz and producing the Freeman chain trains in eight directions and ian a size '1' from the obtained handwritten graphic data to perform the chain coding. CONSTITUTION:When the transmission is performed by means of the DPCM coding, this coding uses the relative coordinates to the continuation of strokes like a conventional graphic transmitter. While in a chain coding mode the relative coordinates obtained from a sampling processing part 3 are developed to the Freeman chain trains in eight directions and in a size '1' at an interpolating chain generating part 15. Thus the chain coding is carried out at a chain coding part 13 to said chain trains. In other words, the Freeman chain train can be coded directly or the DPCM (differential chain) coding system which codes the differential of the chain train can also be available.

Title: Platen drag mechanism for thermal printers
IPC: B41J15/16
Filed: 1993-02-19
Abstract: PURPOSE: To effectively prevent the position shift in dye transfer, etc., in such a way that a means for producing drag for the rotation of the drum that is opposite to the rotation of a drive means is provided to obtain reverse tension that is larger than disturbance by a slip produced in a heating element and an adhesion phenomenon. CONSTITUTION: A platen drag application mechanism is coupled to a platen drum 12 so that platen drag torque is imparted clockwisely when capstan drive torque is imparted anticlockwisely. The platen drag torque is set to be larger than the maximum adhesion force which a thermal print head 10 can impart to a receiver paper 14 in a printing station. Since the platen drum 12 is rotated by the advancing movement of the receiver paper 14, e.g. a platen drag application mechanism is used as a generator having an armature winding connected to a resistance load so that the current generated in a rotating armature flows to a load resistance, and thus, a load of a motor 1 generator is reduced and reverse torque is produced in the platen drum 12.

Title: Endoscope for laser treatment
Inventor: NISHIGAKI SHINICHI
IPC: A61B1/00
Filed: 1988-02-12
Abstract: PURPOSE:To prevent a beam guide fiber to be used from receiving the adverse effect of buckling by relieving and absorbing the expansion or contraction under cooling of a laser probe in the axial direction thereof, by providing an extension and contraction part freely expansible and contractible in the axial direction to the protective tube allowed to cover the beam guide fiber. CONSTITUTION:When the irradiation with CO2 laser beam is continued by a CO2 laser beam guide fiber 22, said CO2 laser beam guide fiber 22 is heated by the transmission loss of laser beam and the total length thereof extends by thermal expansion. This extension is absorbed by the connection means 32 formed between the connection cylindrical part 31 of an operation part C and the leading end part of the protective tube 29 for the beam guide fiber 22. That is, since the connection part 32 is composed of an extensible and contractible coil 27, even when the protective tube 29 for the beam guide fiber is expanded, said coil extends so as to follow the extension quantity thereof. Therefore, no buckling force is applied to the CO2 laser beam guide fiber 22. Even when the CO2 laser beam guide fiber 22 is contracted by cooling, the connection means 3 is contracted so as to follow said contraction and, therefore, no tensile force is applied to the CO2 laser beam guide fiber 22.

Title: Clamping mechanism of information recording disk
Inventor: HASHIMOTO MITSUAKI
IPC: G11B17/028
Filed: 1979-03-16
Abstract: PURPOSE:To ensure the eccentricity-free clamping for the information recording  disk, by energizing the retainer to press the centering cup into the elastic ring and  then pressing the centering cup to the center hole of the information recording disk. CONSTITUTION:When retainer 16 is pressed toward arrow (a) against the elastic force of retainer 16, the engagement between holder 12' and centering cup 12 and retainer 16 is cancelled. Thus cup 12 is pushed downward by spring 13 to be pressed into elastic ring 10. As a result, ring 10 is pushed open outward for taper part 11, and thus the center hole of information recording disk 1 is pressed to be clamped. In this case, part 11 is pressed to the upper end of the center hole via ring 10, and accordingly the accurate coincidence is obtained between the center of spindle 17 and the center of disk 1 when viewed from the information reading side. And then holder 12' is pushed up toward arrow (b) against the energizing force of spring 13 to secure the engagement between protruded part 14 at the upper end of the holder and catch part 15 of the retainer. And thus ring 10 resets to its original state by the elastic force, thus facilitating the attachement/detachment of disk 1.
