Title: Recording head for picture recording device and manufacture thereof
Inventor: OKADA RYOJI
IPC: G03G15/05
Filed: 1990-04-25
Abstract: PURPOSE:To increase the flux density of the end parts of recording electrodes and the bonding strength of toner in order to improve the resolution of recording picture by forming an organic thin film having a specific thickness between the recording electrode and a magnetic sheet. CONSTITUTION:An organic thin film 4 is formed on the surface of a magnetic sheet 1 by electrodeposition, cleaned with flowing water then dried. After forma tion of the organic film 4, the magnetic sheet 1 is laid on a base plate 3 on which recording electrodes 2 are produced by etching. They are then heated in a nonoxidizing atmosphere to polymerize and harden the organic film so as to bond together the magnetic sheet and the base plate. This method permits a uniform attachment of the sheet and the base plate with the magnetic sheet and the recording electrode insulated from each other and with a gap of 1-20 mum produced therebetween. Although the organic film can be provided on either magnetic sheet or recording electrode side, its film thickness is 1-20 mum.

Title: Wire electric discharge machine
Inventor: MORISHITA HIROAKI
IPC: B23H7/00
Filed: 1986-05-13
Abstract: PURPOSE:To improve abrasion resistance on a top face and reduce the extent of thermal deformation as well as to make the unit inexpensive and highly accurate electric discharge machining performable, by applying electroless plating to the top of a workpiece setting surface plate. CONSTITUTION:An electroless plating layer 20 is applied to the top of a setting surface plate 3. Therefore, abrasion resistance on the top face is improved, and such as fear that a workpiece 2 might be tilted when it is set to the surface plate is brought to nothing. In addition, this setting surface plate 3 is not required to be made of a SUS304 system material having an anticorrosive effect as in the past, that is, it is enough to be steel in use for an ordinary structure, thus it can be made cheap in price. Moreover, in a way of making the steel from the SUS304 system, a coefficient of linear expansion is reduced and, what is more, a deformed variable of the setting surface plate 3 due to thermal deformation is reducible, so that still higher accurate electric discharging can be bought to fruition.

Title: Simultaneous preparation of beta-sic with stabilized zirconia
Inventor: YOSHIDA YASUO
IPC: C01G25/02
Filed: 1981-07-10
Abstract: PURPOSE:To obtain beta-SiC and stabilized zirconia at once in reacting zircon sand with a carbonaceous material to form ZrO2, by using CaO, etc. together, and reacting the formed vapor-phase silicon oxide with the carbon. CONSTITUTION:Zircon sand, carbon powder and one or more powders selected from CaO, MgO and Y2O3 or a compound powder convertible into the oxides by heating are mixed and granulated, and a carbonaceous granular material is placed in the periphery of the granulated material and heated at 1,500-2,100 deg.C in a nonoxidizing atmosphere. Thus, the silica in the granulated material is converted into silicon oxide in the vapor phase and released to the outside of the granulated material. The released silicon oxide is then reacted with the carbonaceous granular material to give beta-SiC. On the other hand, stabilized ZrO2 in which one or more in the mixture are present substantially in the form of solid solutions remains in the granulated material. The resultant beta-SiC is then separated from ZrO2 by the difference in particle size or specific gravity.

Title: Optical system driving method
Inventor: HAYASHI MASAYUKI
IPC: H04N1/04
Filed: 1978-09-06
Abstract: PURPOSE: To make possible operating the optical system at a constant acceleration with a simple constitution by performing scanning of the optical system by the use of a pulse motor for a driving source.  
     CONSTITUTION: An optical system 11 is driven by a motor 4 via belt 12. When the start signal is applied to a VOC 15 and a counter circuit 16, the output A of the circuit 16 becomes logic 1 and a pulse is generated from a triangle wave generating circuit 17. This pulse enters the VOC 15 through a voltage control circuit 18 which in turn emits the clock pulses D of the frequency proportional to its input voltage C, causing the motor 14 to be run by a driving circuit 19 at the number of revolutions proportional to the output voltage of the circuit 17. Hence, the motor 14 runs forward under constant accelerating voltage because the output voltage of the circuit 17 increases or decreases constantly with respect to time. The circuit 16 counts the pulses from the VOC and when it counts the number of pulses corresponding to the timing at which the optical system 11 comes at the intermediate point (a), the output A becomes logic value 0. As a result, the output voltage B of the circuit 17 begins to decrease and the running speed of the motor 14 begins to lower. When it comes to the reset point (b), it stops.

Abstract: PROBLEM TO BE SOLVED: To make avoidable such problem that clothes different from clothes which a customer images, are unsillingly finished, by mapping and composting an image of raw materials of clothes stored in a color pattern image storage means for raw materials for image information modified by a figure information modifying means. SOLUTION: The figure information modifying means 119 inputs measured values of parts representing physical features of the head, shoulders, waist, legs, etc., of the user and modifies a design image into a design image based upon the measured values. Further, the raw material color pattern image information storage means 112 stores image data obtained by reading images of raw materials sch as actual texture by a scanner. A raw material color pattern setting means performs mapping calculation using a light and shade image obtained by generating an image of some raw material from the design image for a part area in the design image of the means 119 and sets the raw material color pattern of this part area as another raw material color pattern. Consequently, a try-on a computer screen becomes possible without the actual clothes.

Filed: 1988-05-02
Abstract: PURPOSE:To produce highly responsible musical sounds by respectively detecting the vibrations of strings and string pressing information at the time of starting musical sound production by means of string vibration presence/absence detecting means and string pressing information detecting means. CONSTITUTION:Upon detecting occurrence of vibrations of strings 105 by means of the string vibration presence/absence detecting means when a player starts to pick the strings 105, a musical sound controlling means causes a musical sound producing means to produce musical sounds at the tone corresponding to the string pressing information (corresponding to a pressed fret position) detected by the string pressing information detecting means following the string pressing operation, for example, fret 103 pressing operation performed by the player just before or simultaneously with the picking operation. Then the musical sound controlling means causes the musical sound producing means to change the tone of the sounds being produced in accordance with pitch information extracted by a pitch extracting means. Thus the information required in the initial stage of sound production is obtained from the string vibration presence/absence detecting means and string pressing information detecting means and the information thereafter is obtained from the pitch extracting means. Thus musical sound control effectively utilizing each feature is performed and musical sounds which are natural and well reflect the intention of the player can be produced.
