Inventor: SHIMIZU MASAAKI
IPC: H04N5/235
Filed: 1983-03-31
Abstract: PURPOSE:To attain ease of detection and display for excessive part of luminous amount by detecting the excess of luminous amount in a video signal by means of the 1st means, modulating a frequency lower than that of a DC voltage by means of the 2nd means and displaying an output of the 2nd means in place of the video signal when the 1st means has an output. CONSTITUTION:The video signal from a VTR or the like is amplified by an amplifier 1, an output of the amplifier 1 is applied to a voltage clamp circuit 2, and a signal clamped by the circuit 2 is applied to a voltage comparator 5. The comparator 5 compares this signal with a reference voltage of a comparison reference voltage source 3 to apply an output pulse corresponding to the excess of luminous amount in the video signal to a switch circuit 4. Further, a low frequency from an oscillator 7 is modulated into a DC voltage by a DC voltage modulator 9, applied to a contact A of the circuit 4 via a voltage clamp circuit 8, and the video signal is clamped by a voltage clamp circuit 6 and applied to a contact B. Then, the contacts A, B of the circuit 4 are changed over by an output pulse of the comparator 6, the output of the circuit 6 is used as the display output in place of the output of the circuit 8 so as to attain the ease of detection and display of the excess part.

Title: Printer and its controlling method
Inventor: MIYASHITA TOMOMI
IPC: B41J19/96
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To easily develop an application software by providing an operation means for determining a conversion coefficient between a minimum displacement unit and a reference displacement unit. SOLUTION: When a basic calculation pitch command is received, printers A and B calculate a conversion coefficient on the basis of the command (step 201). Since the proper minimum pitch (pa) of the printer A is 1/144 inch, the conversion coefficient Ka is set to Ka=1/(n2×Pa)=144/720=1/5. Further, since the proper minimum pitch of the printer B is 1/240 inch, the conversion coefficient Kb is set to Kb=1/(n2×Pb)=240/720=1/3. Thereafter, line feed rate setting command is executed (step 202). In this case, n1 is a variable for converting a lateral-directional pitch, and n2 is a variable for converting a vertical- directional pitch.

Title: Data base enquiry processor
Inventor: SHIMIZU SATOSHI
IPC: G06F17/30
Filed: 1988-03-14
Abstract: PURPOSE:To develop a data base enquiry program smoothly by generating an object program which performs retrieval by referring to data base definition information at the time of execution. CONSTITUTION:When the data base definition information 34 is referred to, an enquiry language compiler 60 generates an executable object program 51 by referring to the definition information, but when not, an inexecutable object program 51 is generated without referring to the definition information. An object converting means 50 converts the inexecutable object program 51 into an executable object program 55 by referring to the data base definition information 34 provided to a data base control system 30 at the time of retrieval execution. Consequently, a program which contains data base enquiry commands including the data base definition information that is not present at the time of application program development is developed smoothly.

Title: Equalizer for printer
IPC: B41J25/308
Filed: 1992-03-17
Abstract: PURPOSE:To miniaturize the whole device by installing an equalizer cam, which is driven and rotated by a driving section rotatably mounted to a head holder and in which a cam edge is abutted selectively against an elastic body and an abutting body. CONSTITUTION:When an equalizer cam is 18 rotated and the cam edges 31a of the equalizer cam are abutted against a leaf spring 32, the equalizer 31 is pushed down by the elasticity of the leaf spring 32, and a head holder 7 is turned downward centering around a support shaft 10. Consequently, a pinch roller 12 is abutted against a feed roller 11, and a printing head 3 is faced oppositely to a platen 1. As a result, the equalizer 31 is revolved, and the cam corners 31a are only abutted selectively against the leaf spring 32 and an abutting body 34, thus easily setting a form 23 without largely burdening the leaf spring 32. Accordingly, a structure, in which the head holder 7 is rotated, and a structure, in which the pinch roller 12 is abutted against the feed roller 11, are simplified extremely.

Title: Method for measuring smoothness of surface of paper
Inventor: NAMIKI KOUJI
IPC: B65H7/02
Filed: 1981-04-20
Abstract: PURPOSE:To make it possible to perform the measurement without destruction, in the measurement of the smoothness of the surface of the paper, by utilizing the correlation between the surface smoothness and heat conductivity. CONSTITUTION:The paper to be measured 2 is compressed to a head part 1 by a platen roller 3 at a constant pressure. The head part comprises a glazed layer 5 on an aluminum substrate 4, a resistor film 6 thereon, a heating part 7 which is a part of the resistor, a connecting line 8, and a wear resisting insulating film 9. Though the surface of the insulating film 9 is nearly perfect surface, there are small concave and convex parts on the surface of the paper to be measured 2. Therefore, a true contact area is smaller than apparent contact  area. The broader the true contact area, the larger the amount of heat conduction, and therefore the larger the decrease in the temperature of the heating  part. Therefore, the temperature T of the heating part is measured with a constant power being supplied, and the difference T0-T, where T0 is the temperature when the paper to be measured is not present, is obtained as an index for indicating the smoothness.

Filed: 1986-03-17
Abstract: PURPOSE:To enable stable ink supply without causing secondary contamination attributable to the destruction of fine particles originating from a filter by connecting a flat surface mesh filter to the orifice of an ink discharging duct for conducting ink from a container to the outside. CONSTITUTION:A bag-shaped container 1 is of such a constitution that a 3 to 4-tier structured aluminum laminated high polymer film is bent and overlapped with the circumferential edges bonded together through thermal melting. An orifice in the ink container set at an ink conduction part 2 is fitted with a flat surface mesh filter 3 by thermally melting the circumferential edge. The recommendable filter material may be any kind of member which is corrosion- resistive to an ink such as synthetic high polymer resin, glass, metal or ceramic. A satisfactory result-yielding mesh size is approx. 5-30mum. This filter 3 securely removes bubbles in the ink, deposits or fine particles attaching to the inner surface of the container. In addition, the filter has no such a risk that it might be destructed, thus insuring an always stable ink supply.

Filed: 1984-03-26
Abstract: PURPOSE:To obtain the titled recording medium having excellent magnetic characteristics and to improve the preparation conditions by forming an Sn layer and a metallic magnetic layer successively on a nonmagnetic substrate with vapor plating. CONSTITUTION:A vapor deposition apparatus 1 is used, and a nonmagnetic substrate 4 is traveled under vacuum around a metallic can 3 from a supply reel 5 to a winding roll 6. At this time, the nonmagnetic substrate 4 is kept at room temp., and Sn is vapor-deposited on the substrate from a vapor deposition source 7. Succeedingly, a metallic magnetic layer is deposited on said undercoat layer of Sn from a vapor deposition source 8. High coercive force and high squareness ratio can be obtained in this way. Since the Sn layer as the undercoat layer consists of a low-melting point metal, the film can be formed at low temps. of the substrate. Accordingly, a high molecular film which is lacking in heat resistance can be used as a nonmagnetic substrate.
