Title: Noise reduction device
Inventor: KANESHIRO ATSUMI
IPC: H04R3/00
Filed: 1993-12-10
Abstract: PURPOSE:To prevent the noise reduction effect from deteriorating even when the temperature is changed by changing the transmission characteristic for the sound cancelling the noise corresponding to the temperature of the peripheral device. CONSTITUTION:The device is provided with a temperature detection part 17 which detects the temperature of the peripheral device and a transmission characteristic correctihg part 18 which changes the transmission characteristic of the part 8 for the temperature detected by the part 17. In the part 17, the temperature of the peripheral device is detected. Since in the part 18, the temperature characteristic of a speaker 14 and that of the transmission characteristic from the speaker 14 to the microphone 15 are actually measured and known, the transmission characteristic of the part 8 is changed to the transmission characteristic corresponding to the temperature detected by the part 17. Thus, the transmission characteristic for the sound cancelling the noise corresponding to the temperature of the peripheral device is made changed so that the actual transmission characteristic and the transmission characteristic so as to produce the noise cancelling sound coincide and the noise reduction effect can be kept high even when the temperature is changed.

Title: Information recording and reproducing device
Inventor: TAKIZAWA MINORU
IPC: G11B20/18
Filed: 1993-12-10
Abstract: PURPOSE:To surely perform the settings of recording and reproducing frequencies with a simple circuit constitution. CONSTITUTION:At first, a reproducing is performed with a recording frequency corresponding to the zone of an original point position. A signal processing circuit 9 checks a reproducing signal from a head 5 and performs a transmission to a setting circuit 7 when a normal reproduction becomes impossible within a fixed time. The setting circuit 7 changes a setting to a recording frequency corresponding to an adjacent zone to output it to a clock generating circuit 8 and then the head 5 performs a recording to an optical disk 1 with the clock signal of a frequency according to the setting. A recording frequency capable of reproducing information is searched by repeating this operation. When the reproducing is performed normally, the recording frequency is stored in a buffer 10. Next, in the case of moving a positioner 4 to the zone of the original point position, information are reproduced by setting the stored frequency. When a reproducing becomes impossible within the fixed time, the reproducing is performed by changing the set frequency to recording frequency corresponding to the adjacent zone. A recording frequency capable of reproducing information is searched by repeating this operation. Thus, even when frequencies are deviated from each other due to device difference, a time till reproduction can be shortened after next time.

Abstract: PROBLEM TO BE SOLVED: To provide a combine for preventing clogging of a threshing net and preventing decline of threshing performance in harvesting wet grain culms. SOLUTION: Since air sent from a blower 74 is jetted from the symmetrical positions of a threshing chamber entrance along the inner periphery of the threshing net 34, even in the case that grains whose surface is wetted by moisture in a wet threshing state are stuck to the threshing net 34 and the threshing net 34 is clogged, for instance, high-temperature air is jetted and blown along the inner periphery of the threshing net 34, the moisture of the grains is dried and the clogging of the threshing net 34 is prevented.  By turning the jetting direction of the sending air to the opposite direction of the rotating direction of a threshing cylinder, in the case that the sending air immediately after being jetted is composed of the air at a high temperature for instance, the temperature is lowered and it is turned to a low temperature since the temperature is taken by the latent heat of the moisture drying of the surface of the wet grains as separating from an air sending start position and the moisture of the grains advanced in the same direction as the rotating direction of the threshing cylinder is dried by a jet whose temperature is gradually raised from the low temperature to the high temperature.

Title: Pattern forming method
Inventor: IKEDA TSUTOMU
IPC: G03F7/00
Filed: 1987-12-11
Abstract: PURPOSE:To simplify a pattern forming process, and to make possible to easily form a fine pattern, even in case of dry etching by forming a crystal layer composed of a monomer on a substrate and subjecting a monomer layer to a solid-phase polymerization by pattern-wisely irradiating ionizing radiation rays or corpuscular rays on the monomer layer. CONSTITUTION:The crystal layer composed of the monomer is formed on the substrate, and the monomer layer is subjected to the solid-phase polymerization by pattern-wisely irradiating the ionizing radiation rays or the corpuscular rays to the monomer layer to form a pattern. Namely, as the crystal of the monomer is used for a resist material, and the crystal layer of the monomer is subjected to the solid-phase polymerization by irradiating the ionizing radiation rays or the corpuscular rays to the layer, the high resolving power having less than the unit cell length of a monomer crystal can be expected as the limit of resolution. Thus, the fine pattern is easily formed, without using a developer.

IPC: B60R21/231
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To prevent the local load from being applied to a developed air bag body by a door arm rest. SOLUTION: A lower end part 32C at the tip in the development direction of an air bag body 32 is folded up to the position of the folding line 32D diagonally upward on the inner side of the air bag body 32, and then, folded in a bellows manner from the tip part side in the development direction to the opening part side. The air bag body 32 is developed in a shape in which the lower part 32C of the tip part in the development direction is developed in the direction approximately orthogonal to the folded line 32D. Because the lower part 32C of the tip part in the development direction is developed while a rear end part 68A of a door arm rest 68 is pressed in the direction of the arrow A, the lower part 32C of the tip part in the development direction of the air bag body 32 is located above the rear end part 68A of the door arm rest 68 when development is completed.
