Title: Magneto-optical recording medium
Inventor: ORUKAWA MASAHIRO
IPC: G11B11/10
Filed: 1990-03-23
Abstract: PURPOSE:To allow overwriting without a bias magnetic field at the time of recording by successively laminating a 1st magnetic film and a 2nd magnetic film in this order from a light projecting surface side and specifying the amt. of the Co to be added to the 2nd magnetic film. CONSTITUTION:This recording medium is laminated with the 1st magnetic film 11 on the light projecting surface side and the 2nd magnetic film 12 different therefrom. The amt. of the Co to be added to the 2nd magnetic film 12 consisting of an alloy of rare earths and transition metals is specified to >=15%. The direction of the magnetization of the 2nd magnetic film 12 is, therefore, previously unified in one direction by a magnet for initialization; thereafter, the magnetization of the 2nd magnetic film 12 is transferred to the 1st magnetic film 11 without being annihilated at the time of recording in a low-power mode. The 2nd magnetic film 12 is locally heated to the Curie point or above by heating with a laser in the case of a high-power mode. The leak magnetic field from the circumference acting on the heated part is then exceedingly increased and the magnetization of the 2nd magnetic film 12 is inverted even without the aid of the bias magnetic field from the outside and the inverted magnetization is transferred to the 1st magnetic film 11 on cooling. The optically modulated overwriting is executed without the bias magnet for recording by switching the high power and the lower power at the time of recording in such a manner.

Inventor: MACHIDA YASUHIDE
IPC: H01L21/027
Filed: 1988-03-28
Abstract: PURPOSE:To make it possible to conduct a pattern data correction at high speed in a short period by a method wherein, pertaining to the sub-fields other than the single sub-field in the center part of a repetitive region, the amount of correction of each pattern of a single sub-field is get in the state as it is.

Title: Hot water supplying apparatus
Inventor: WATANABE HISAYASU
IPC: F24H1/10
Filed: 1994-03-18
Abstract: PURPOSE:To cancel a change amount of a water flow rate due to a differential pressure at the time of supplying hot water and to obtain a suitable water amount by detecting a differential pressure at between upstream side and downstream side of a water flow control valve, driving a gear motor before supplying hot water, and setting an initial opening of the valve based on the differential pressure. CONSTITUTION:Heat is supplied by a gas burner 13 to a heat exchanger 12 through a water supply tube 20 and a water flow control valve 50 is controlled at its opening by a gear motor 56 provided at a water supply tube 20. When the motor 56 is driven in a closing direction for 2 seconds in the case where a differential pressure between front and rear sides of the valve 50 is large, an initial opening of the valve 50 is largely throttled to limit its flow rate to prevent discharge of the hot water of the exchanger 12 in a short time, and hence cold water can be sufficiently warmed. When the pressure is low, the motor 56 is driven in the closing direction only for 1sec, throttling of the initial opening of the valve 50 becomes small to prevent long retention of hot water retaining in the exchanger 12, thereby preventing excess heating of part of the remaining hot water by the exchanger 12 in which its thermal efficiency is recovered.

Filed: 1982-04-30
Abstract: PURPOSE:To attain the continuity of recording intervals between a signal after recording and an editing recording signal, by applying a control signal based on the final tracking error signal at reproduction to a servo circuit at the edition and recording. CONSTITUTION:At the assembling editing mode, signals V and A recorded already, and a new signal is edited and recorded after point P and succeeding. In this case, a changeover switch 8 is selected to a contact ''as'', and an output the value of which is decreased with a long time constant is applied from a time constant circuit 6 to a servo circuit 9 in response to the final tracking error signal at reproduction.

In the insertion editing mode, the switch is selected to the contact ''ins'', an error signal from a phase measuring circuit 5 at the point P is held to a point Q with a hold circuit 7, and the hold voltage is applied to a circuit 9. In the split edition mode, the signal A is left between the points P and Q, and only the signal V is edited and recorded newly. In this case, a control signal (a) remains as it is, the switch 8 is selected to a contact ''sp'', and the error signal on a track T of the signal A between the points P and O is applied to the circuit 9.

Inventor: KUMANO KATSUFUMI
IPC: B29L7/00
Filed: 1995-03-30
Abstract: PURPOSE: To certainly reduce the S-shaped curl phenomenon of a three-side sealed bag used as a film for packing retort food after heat sterilization treatment by setting the direction of the orientation main axis of an α-crystal to a specific angle with respect to the longitudinal or lateral direction of a film. CONSTITUTION: In the constitution of a biaxially oriented polyamide resin film, the direction of the orientation main axis of an α-crystal is set to an angle of 14 deg. or less with respect to the longitudinal or lateral direction of the film. This film can be easily obtained by longitudinally stretching a substantially non-oriented polyamide resin sheet based on nylon 6 of which the relative viscosity is pref. 2-3.5 over two stages and biaxially stretching this stretched film in area magnification of 9 times or more before thermally fixing the same. There is no special limit in the longitudinal and lateral stretching magnifications of the film but, in order to obtain a more uniform film free from thickness irregularity, it is desirable that the longitudinal stretching magnification is set to 1.5-6 times and lateral stretching magnification is set to 1.5-7 times.

Title: Copying apparatus
Inventor: MAKINO YOSHIMI
IPC: G03G15/04
Filed: 1979-06-12
Abstract: PURPOSE: To make the state checking of the subject by the operator easy by forming the subject cover by the material which reflects the light of the frequency sensitivity region of the photoreceptor and transmits the light outside the region.  
     CONSTITUTION: When the light out from a light source 1 arrives at the subject 3 on the surface 2 to be copied, it is partly absorbed and the rest is reflected and the light corresponding to the subject 3 reaches a photoreceptor 4. On the other hand, the light out from the light source 1 arrives at the subject cover 5 being the background of the subject 3. If the transmission characteristic of the cover 5 is beforehand so made as to peak at around 450μ, the bluish light reaches the operator 6 and the other light reflects and arrives at the photoreceptor 4. This enables the operator 6 to check the contour of the subject 3 and since the light of nearly the entire sensitivity region arrives at the photoreceptor 4, the image of the background equivalent to that when the subject of a white color is copied is formed.

Abstract: PURPOSE:To easily discriminate the display of the summary of plural files from that of the content of the files by an operator by superimposing a card graphic at every row when the summary of the plural files is displayed, and displaying the content of the files as it is when they are displayed. CONSTITUTION:When the leading part of each file is displayed, the character of the card graphic 9 is superimposed. It is applied also on the graphic 11. The character of the graphic 10 is superimposed on second and after digits. Thereby, the picture of the graphic 12 can be displayed. In other words, a digit counter is set at 1. One character is taken out from a file memory 8, and is developed at a registration buffer 6 as an image. Also, the overwrite of the graphic 9 is further performed when the number of digits shows one, and that of the graphic 10 when it shows the number other than one. A synthesized character is sent to a display part 3. Next, the number of digits is increased by one. When the number of digits shows the final of a display picture, the number of digits is returned to one, and a display position is moved to the next row, then, such operation is repeated. In such a way, it is possible to easily discriminate the picture displaying the content of the file from the summary display of the plural files.
