Title: Light guide member
Inventor: HASEGAWA KAZUO
IPC: G02B6/08
Filed: 1986-09-22
Abstract: PURPOSE:To pass only light parallel to an optical axis selectively and to simplify the structure of an optical system and reduce its size by using an optical fiber consisting of a light-transmissive core and a light-absorptive clad which covers the core and is nearly equal in refractive index to the core. CONSTITUTION:Many optical fibers each consisting of a light-transmissive core 10 and a light-absorptive clad 11 which covers the peripheral surface of the core 10 are stacked in one body, and the core 10 and clad 11 are nearly equal in refractive index to each other in this case. For example, the optical fiber 12 consists of the core 10 made of a light-transmissive material such as glass and the clad 11 made of a light-absorptive material such as black glass which covers the core 10, and the core 10 and clad 11 are nearly equal in refractive index. When random light is made incident from one end of a light guide member, light P1 oblique to its optical axis is absorbed by the clad 11 having high light absorptivity and only light P2 parallel to the optical axis passes through the light-transmissive core 10 and reaches the other end.

Title: Heat discharge mechanism
Inventor: KAYAMA TAKASHI
IPC: G06F1/20
Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To securely improve heat discharge effect and to prevent foreign matters such as dust from entering into a housing by opening a heat discharge hole in accordance with the rise of the inner temperature of the housing thereby discharging generated heat to the outside. SOLUTION: When power is turned on, a heating element 12 generates heat and a fun unit 26 starts rotating. In such a state, a sliding door 22 closes a hole 21b and inner generated heat is discharged from a lateral hole 21c on a side wall part 21a. When the inner temperature of a housing 21 rises, the spring force of a coil spring 23 made of shape memory alloy, which energizes the door 22 to right, becomes larger than the spring force of a coil spring 24, the door 22 is moved rightwards to open the heat discharge hole 21b. The generated heat of the heating element 12 is discharged to the outside of the housing 21 through a heat transfer sheet 29 and a heat sink 27 to suppress the temperature rising in the housing.  When power is turned off, the temperature drops to return the spring 23 to the shape of a room temperature, then the door 22 is moved leftwards to close the heat discharge hole 21b by the door 2, thereby preventing dust or the like from entering the housing.

IPC: B01J3/04
Filed: 1999-08-05
Abstract: PROBLEM TO BE SOLVED: To remove reaction products such as salt, and the like, discharge the same outside, enhance smooth rotation of a movable shaft and prevent a sealing member from being damaged by attaching a scraping means, a crushing means, a stirring means and a coveying means for the reaction products on the movable shaft partly faced to an interior of a pressure resistant reactor and held in a sealed state. SOLUTION: When a reaction object matter is fed into a reaction chamber 12 of a pressure resistant reactor 11 through a feed pipe 26, the reaction object matter is reacted and reaction products are discharged through an outlet 16 via a bottom chamber 15. If salt, and the like, as the reaction products adhere on an inner surface of the reactor 11 or are deposited on the bottom chamber 15, a drive mechanism 12 is actuated to rotate a movable shaft 20. The deposited reaction products are crushed by an agitation blade 25 attached to the movable shaft 20 and the reaction products adhering on the inner face are scraped off by a scraper 31 attached to the movable shaft 20. At this time, water is supplied through fluid supply holes 23, 24 and the reaction products falling into the bottom chamber 15 are efficiently discharged outside though the outlet 16.

Title: Chrominance signal reproducing device
Inventor: YAMAMOTO NAOKI
IPC: H04N9/79
Filed: 1985-10-04
Abstract: PURPOSE:To effectively prevent a color stripping in a long hour mode reproducing time by setting a killer level in the long hour mode reproducing time at the same level as that in a reference mode reproducing time. CONSTITUTION:A reproducing signal obtained from a recording medium is inputted from an input terminal 1, being sent to the first and the second input amplifiers 2 and 16. the reproducing signal sent to the second input amplifier 16 is amplified with an amplification factor larger by 4dB than that of the first input amplifier 2, being sent to a switch 15. The switch 15 is switched with a mode switching signal from an input terminal 17: it is switched to an SP side in the reference mode reproducing time and to and to an LP side in the long hour mode reproducing time. Since a burst level in the long hour mode reproducing time at the input terminal 1 is lowered by about 4dB than the burst level in the reference mode reproducing time, the burst levels added to an ACC amplifier are equal, thereby the killer level being equal.

Title: Rotary roll device
Inventor: YAMAMURA AKIHIKO
IPC: G11B15/60
Filed: 1983-11-28
Abstract: PURPOSE:To reduce the pressing force of a magnetic tape to a flange by using a member having a high frictional coefficiency to form a contact surface of a rotary roll to the magnetic tape and holding said member with a means which can move toward the rotary shaft of said roll. CONSTITUTION:A member 11 having a high frictional coefficiency has low strength toward the rotary shaft of a rotary roll 12 and high strength toward the circumference of the roll 12 since many slits 10 are provided to the member 11 constituting the roll 12. A magnetic tape 15 is driven with control given from a flange 13 of the roll 12. If a shift 9 is produced, the member 11 is shifted to a position 11' to absorb the shift 9. This reduces the pressing force of the tape 15 which is produced by the attachment variance of the roll 12 to the flange 13. In addition, a shift amount of the tape 15 can be detected easily.
