Title: Manufacture of deep drawn container
Inventor: KOSHIZAKA ATSUSHI
IPC: B21D51/18
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To enable the formation of a fine radius in a bottom surface part of a deep drawn container by executing the deep drawing with a radiused part formed at the connected part between the projecting part and the side wall part of a punch and a radiused part formed at the opening end side and the inner diameter side wall part of a die and executing the formation with the recessing part of the punch and the projecting part of the die. SOLUTION: The projecting part 5a of a female die 5 is formed as ramming state with the recessing part 4a of the punch 4 through a material 1b, and the recessing part 2a of the container is formed and further, in the connecting part 2d between the recessing part 2a and the side wall part 1a of the container, the fine radius R formed on the connecting part 4d of the punch 4 is transfer-formed. Since a gap 9 between the recessing part 5b of the female die 5 and the projecting part 2b of the container exists, the ramming is executed only in the position at the projection part 5b of the female die 5 and the working load is reduced. At the time of deciding the dimension in the height relation between the recessing part 5b of the female die 5 and the projecting part 4b of the punch 4, the gap 9 can arbitrarily be set by considering the thickness of the material 1b. Therefore, the fine radius R at the bottom surface of the deep drawn container can be formed with the deep drawing work.

Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To enable the efficient high-speed transmission between a recording and reproducing device and a computer without depending on system constitution. SOLUTION: The DVC data obtd. at a high speed (for example, quadruple- speed) is converted to a PCI(peripheral component interconnect) bus type and while this data is DMA transferred to a first memory means, the data is subjected to AV sepn. and sub-code data processing with this first memory means. Further, an asynchronous DMA transfer instruction is issued at the point of the time the DVC data is accumulated by the regulated number of frames, by which the transfer of the DVC data to the plural SCSI controllers on an SCSI interface is started at every one frame. As a result, the time base multiplexing of the DVC data inputted and outputted at the high speed to and from the main memory via the PCI bus occurs and the high-speed transfer is made possible. Namely, the embodiment of the recording of the DVC data of the quadruple-speed in real time to an HDD array is made possible.

IPC: H04B10/114
Filed: 1989-12-29
Abstract: PURPOSE:To attain long service life and low current consumption of a transmission section by starting transmission LEDs grouped corresponding to each photodetection level in the talking direction. CONSTITUTION:When a mobile station makes transmission from a direction A of a fixed light receiving and emitting section, its stimulated output is received simultaneously by photodetectors(PD) 27, 28, 35, 36, the light is photoelectric-converted by light reception buffer circuits 41, 43 and amplified by light receiving amplifier circuits 42, 44. The amplified carrier levels are compared by a comparator 45 and since a mobile station makes transmission from the direction A, the level of a light emission amplifier circuit 49 in the direction A in the comparison output gets higher. Then an LED group 37 is lighted up for a talking carrier while being driven by an LED transmission drive circuit 47 in the same direction A. Thus, the entire current consumption of the light emission circuit is less and number of LEDs lighted simultaneously is less, then a voltage driving the LEDs is suppressed small and the LEDs are lighted by directions and not always lighted, then long service life is attained.

Title: One component heavy metal fixing agent
Inventor: HORI YOSHIHIRO
IPC: B09B3/00
Filed: 1998-12-02
Abstract: PROBLEM TO BE SOLVED: To prevent the elution of heavy metals surely by preparing a one component heavy metal fixing agent for preventing the elution of heavy metals from heavy metal-containing ash, heavy metal-polluted soil, and the like, to contain specified amounts of a phosphoric acid compound, an iron (III) salt, and water, respectively. SOLUTION: A one component heavy metal fixing agent which can fix heavy metals including lead, cadmium, arsenic, and antimony effectively to surely prevent the elution of them is obtained by incorporating 5-50 wt.% of a phosphoric acid compound, 1-15 wt.% of an iron (III) salt, and 20-94 wt.% of water. In the fixing agent, the iron salt fixes the heavy metals by a process in which produced iron hydroxide and the heavy metals form scarcely soluble salts to be coprecipitazed. The phosphoric acid compound fixes lead and cadmium in heavy metal-containing waste and acts mutually with the iron salt to strengthen a heavy metal fixing capacity. An iron (II) salt can be incorporated in an amount not to damage the stability of the agent.
