Title: Toner for developing electrostatic charge image
Inventor: TANIGAWA HIROHIDE
IPC: G03G9/087
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To impart plasticity, releasability, peelability and lubricity to a toner and to obtain the toner excellent in fixability, anti-offsetting property and image durability by using two kinds of waxes different from each other in melt viscosity at a specified temp. SOLUTION: This toner contains two kinds of low viscosity waxes. One of the waxes has <22mPa.s melt viscosity at 120 deg.C measured with an E type viscometer. When the melt viscosity is 1-15mPa.s, the wax improves fixability because of high plasticity but wax films oozing to the surfaces of toner particles are weak because of low melt viscosity and do not produce a releasing effect. The other has 22 to <100mPa.s melt viscosity. When the melt viscosity is 30-80mPa.s, wax films oozing to the surfaces of toner particles have enhanced strength because of moderate melt viscosity and produce superior releasing and peeling effects.

Inventor: YABE KATSUHIKO
IPC: H04M11/06
Filed: 1986-11-05
Abstract: PURPOSE:To summarize and arrange the contents of respective types of inquiries without loading an unnecessary burden to the opponent of calling by fitting an external terminal for picture drawing data at a voice and depicted picture simultaneous communication telephone terminal device. CONSTITUTION:When a calling opponent is a telephone set with an individual sound, changing-over switches 24-24b and 25-25b are connected, a telephone set 22 is connected to a telephone line 11, and therefore, the calling can be executed by a voice with the opponent. At this time, since the output of a picture drawing data circuit is removed from an external output terminal 23, the communication can be executed by a terminal and picture drawing separate from the opponent of communication by a sound. Thus, since an external output terminal is provided at the picture drawing data circuit of a voice and depicted picture simultaneous communicating telephone terminal device, the communication can be executed by the terminal and picture drawing separate from the opponent of the communication by the sound. Thus, without loading an unnecessary burden to the telephone opponent, while the contents of the inquiry are heard on the phone, the data can be sent to another voice and depicted picture simultaneous communication telephone terminal and the summarization and arrangement of the contents can be easily executed.

Title: Sliding structure of operation member
Inventor: OISHI KOJI
IPC: G05G1/04
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To obtain a uniform and smooth operating force over an entire operation range and also to reduce cost by setting an engaging plane which corresponds to a curve that is antiphase to a load characteristic curve which is formed by the weight of a member to which the operating force is transferred. SOLUTION: A curved engaging plane which comes into contact with a ball 50 under pressed action of a coil spring 48 is formed on a click member 54. The engaging plane consists of a 1st engaging plane 60 whose radius of curvature is large and a 2nd engaging plane 62 which continuously joins the plane 60 and whose radius of curvature is smaller than the one of the plane 60. The ball 50 slides and displaces along the plane 60 under pressed action by the spring 48, pressed to plane 62 whose radius of curvature is small by the repulsive force of the spring 48 when it reaches the plane 62 and slides and displaces along the plane 62. This makes a load characteristic curve that is given to an operation lever constant and can give a uniform and smooth operating force over the entire operation range of the operating force.

Title: Language learning system using video tape recorder
Inventor: TAKAHASHI TSUTOMU
IPC: G09B19/06
Filed: 1987-10-17
Abstract: PURPOSE: To optionally select a telop display on a screen or its removal as a reproducer intends by recording the original language on a main audio track of a video cassette and a translation character signal of the original language and a control signal on a subordinate audio track or in vertical blanking periods. CONSTITUTION: While a video signal is recorded on the video signal track of the video cassette set in the video cassette recorder having a sound multiplex video recording and reproducing function and the original language is recorded on the main audio track of the video cassette, the translation character signal of the original language and the control signal are recorded on the subordinate audio track of the video cassette or in vertical blanking periods. Therefore, when a learner operates the sound multiplex mechanism of the video cassette recorder to stop the output of the subordinate audio track, the telop of translation characters disappears from the screen and only the video and the sound of the original language are reproduced. Consequently, the learner selects the display or nondisplay state of the translation characters according to the progress of learning and continues to learn.

Title: Nc data generating system for cutting of curved surface
Inventor: SEKI MAKI
IPC: G05B19/4093
Filed: 1989-10-11
Abstract: PURPOSE:To secure the maximum dimensional accuracy within a range where no cut-in pnenomenon occurs by replacing the diameter of a concave circular arc with the cutter diameter and defining automatically again a concave circular arc of the least size where no cut-in phenomenon occurs when a cutter diameter is designated in a size larger than a concave circular arc defined by the curved surface cutting information which is obtained previously. CONSTITUTION:A designated working cutter diameter is inputted to an automatic programming device together with the curved surface cutting information obtained previously. The programming device detects a concave circular arc 30 defined by the curved surface cutting information and compares the size of the arc 30 with the working cutter diameter (r). When the former size is smaller than the latter one, the diameter of the arc 30 is replaced with the diameter (r) and the curved surface cutting information is defined again. Then the working path of the cutter is calculated based on the redefined cutting information. As a result, a cut-in phenomenon can be prevented regardless of the size of the diameter (r). Then the shape precision of a work is maintained.
