Title: Syringe assembly
Inventor: NIOORU SUUINII
IPC: A61M5/32
Filed: 1990-03-30
Abstract: PURPOSE: To obtain a syringe assembly which can be separated by a suitable rotational power or a twisting power without incorrect needling by separating, for example, a needle shield from an outer tube with use of a forcing display means and then separating the forcing display means. CONSTITUTION: When a user holds a syringe assembly, he checks a forcing display collar by his hand and confirms that a fixing means such as a welded part 49 being fixed and not destroyed. If the welded part has been forced open already, the collar can be fallen off the syringe or removed easily by a slight power when the needle shield is oriented downward. If the collar has not been forced open yet, the user applies a rotation power along a longitudinal axial line of the needle shield 32 with keeping the outer tube 21. By rotating the needle shield against the outer tube, a cam surface contacts with an inverted surface and provides a power on the inverted surface.

Title: Production of single crystal
Inventor: MATSUMURA SADAO
IPC: C30B15/14
Filed: 1980-06-23
Abstract: PURPOSE: Grown single crystal is gradually cooled without being taken out of the crystal-drawing up device to inhibit the development of thermal distortion during the cooling process, thus producing single crystals of high quality and high processability.  
     CONSTITUTION: When a single crystal is grown by drawing up the seed crystal 5, the heater is pulled up by a certain distance from the crucible 1, the grown single crystal is separated from the surface of melted liquid 6 and placed in the zone surrounded with heat reflector 3. As kept in this state, the work coil 2 is gradually raised and simultaneously the heating power is reduced according to the prescribed program. The gradual cooling produces desirable single crystals without deformation and microcracks with high reproducibility in high yield.

Title: Signal converter
Inventor: JIYON JIEI POUROSU
IPC: H03M7/32
Filed: 1995-03-15
Abstract: PURPOSE: To attain an operation with the limited number of pins and various serial data input formats by dividing the master lock signal of a signal converter having a three wire serial interface. CONSTITUTION: All three functions can be obtained by using a pin 2 of a D/A converter IC20. When it is necessary for a user to report the change of a de- emphasis DEM filter, an inside serial clock SCLC is automatically generated by using the pin 2 as a static DEM control pin DEM. For example, in a system in which serial data SDATA are asynchronous with a master clock MSCLK, when the user necessitates an outside SCLK, the switching of the DEM is automatically unnecessitated by using the pin 2 as the SCLK input. In any case, when it is necessary for the user to operate with an SDATA format except an initialization format, a 8 bit constitution sequence CONFIG is applied to the pin 2. As a result, the maximum flexibility can be obtained with the limited number of pins.

Title: Circuit for detecting size of original
Inventor: YOKOYAMA HIROSHI
IPC: H04N1/00
Filed: 1983-05-16
Abstract: PURPOSE:To decrease the space and to simplify the function by providing a special pattern reflecting plate which reflects light and leads it to a picture signal reading circuit of a facsimile device, an original position detecting circuit, original position measuring circuit and an integration circuit measuring original positions several times. CONSTITUTION:When the reading position reaches a part of an original, no rectangular wave is lost from a picture signal 103, a high level or a low level is consective; a timer 10 or a timer 9 continues counting and an output of the timer 10 or the timer 9 goes to high level. Thus, an output 104 of an OR gate 11 goes also to high level. In this case, a latch 13 latches outputs 105, 106 of a timer 12. If an original is set obliquely or the end of the original is read at first, the said operation becomes unstable. In order to avoid this unstable operation, outputs 107, 108 of the latch 13 are counted n-times by a timer 16 through an OR gate 15 and an output 110 of the timer 16 goes to high level when the output 104 is stable.
