Title: Absorbing element of oil-containing liquid
Inventor: ONO SADATOSHI
IPC: B01J20/28
Filed: 1992-10-26
Abstract: PURPOSE:To sufficiently develop the water absorbing action of a highly water- absorbable resin by obtaining an absorbing element of an oil-containing liquid by receiving the highly water-absorbable resin and a highly oil-absorbable resin in a water and oil permeable exterior material composed of a water-resistant and oil-resistant material. CONSTITUTION:An absorbing element is obtained by receiving a highly water- absorbable resin 2 and a highly oil-absorbable resin 3 in a water and oil permeable exterior material 1 composed of a water-resistant and oil-resistant material. Since an oil component is absorbed by the highly oil-absorbable resin 3 and moisture is absorbed by the highly water-absorbable resin 2 in this absorbing element, when the absorbing element absorbs an oil-containing liquid such as drip generated from fishes and shellfishes or meats, the water absorbing action of the highly water-absorbable resin 2 is not obstructed so much and the absorbing element can be used in a suitable state.

Title: Magneto-optical disk medium
Inventor: TOKITA TAKASHI
IPC: G11B11/105
Filed: 1989-11-03
Abstract: PURPOSE:To enable heating of a recording film with smaller electric power and to obtain high recording sensitivity by using an adhesive resin into which a material having lower thermal conductivity than that of the adhesive resin is added. CONSTITUTION:Two magneto-optical disks 1a, 1b are stuck with recording films 5a, 5b facing to each other with an adhesive resin 2a. Such a material 13 having lower thermal conductivity than that of the adhesive resin 2a is added to the adhesive resin 2a, which results in decrease in thermal conductivity of the total adhesive resin 2a. Thereby, dissipation of heat due to thermal conduction to the adhesive resin 2a is decreased on heating the recording films 5a, 5b, so that the recording layers can be heated rapidly with smaller electric power. Thus, recording sensitivity of the magneto-optical disk medium 14a can be increased.

CONSTITUTION: Rice is charged in a rice washing tank 3 from a charging port 9 and, next, water is charged in the rice washing tank 3 to a degree immersing the upper surface of rice. When an acceleration member 7 is erected to be opposed to the inner wall surface of the rice washing tank 3, a changeover switch 15 is closed and the rice washing tank 3 is rotated at a low speed and rice is pressed to the inner wall surface of the inner wall surface of the rice washing tank 3 by the acceleration member 7 and grains of rice are mutually rubbled and rice bran is removed from grains of rice to be mixed with water. The rice washing tank 3 is rotated for about several ten sec by the timer circuit in a controller 14 to stop. When the acceleration member 7 is housed under an upper lid 4, the changeover switch 15 is changed over and the rice washing tank 3 is rotated at a high speed and water mixed with rice bran is centrifugaly dehydrated to be accumulated in a drain container 13 through a drain hole 12. The liquid sealed in the cavity 6 of the upper end outer peripheral part of the rice washing tank 3 is moved to a position correcting the unbalance of the rotation of the rice washing tank 3 to function as an automtic balancer.

Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To realize a method and a device for storing and controlling the data of an external memory by which the service life of a flash memory is prolonged without needing the waiting time for data erase and the time of calculating the number of calculation. SOLUTION: Flash memories 7a-7c for re-writing store data in the order from 7a to 7c and a CPU 2 applies garbage collection of the memory 7a to the 7d in the flash memory 7d, 7e for garbage collection when the free region of memory 7c is exhausted and at the same time, when a write access comes from a host 1, gives first precedence in the application of this to memory 7d. When the garbage collection of memory 7a finishes, the garbage collection of memory 7b is applied to memory 7e and concurrently data of memory 7a is erased. Memory 7c becomes flash memory for rewritten data by the CPU 2. When the garbage collection of memory 7b finishes, data is erased in a lump to make memory 7e flash memory for rewritten data. Next, garbage collection of memory 7c is similarly processed.

Title: Semiconductor chip and tab tape
Inventor: KAWANISHI DAIZO
IPC: H01L21/60
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To provide an arrangement of pads which does not cause deterioration of yield in a narrow pitch configuration of pads. SOLUTION: A plurality of pads 12, which are arranged on the surface of a semiconductor chip 11 and bonded to an inner lead of a TAB tape, are arranged not parallel to each edge of the semiconductor chip 11 but slantedly to each of the edges. As a result, the pitch of the pads 12 is enlarged as compared with the case when the pads are arranged parallel to each of the edges. Hence, when the pad pitch is narrow and the pads are arranged in parallel, the pad pitch is widened by almost 1.2-1.4 times, since the pads 12 are slantingly arranged. Thereby the positioning at the time of bonding the pads 12 to an inner lead of the TAB tape is facilitated, the occurrence rate of defective products in an inner lead bonding process can be discouraged, and deterioration in yield can be prevented with respect to the narrow pitch configuration of the pads 12.

Title: Vibration-type gyroscope
Inventor: TOMIKAWA YOSHIRO
IPC: G01C19/5642
Filed: 1994-10-28
Abstract: PURPOSE: To convert Coriolis force to vibration in different direction and to mount a vibration-type gyroscope to a thin device in the vibration-type gyroscope utilizing the Coriolis force. CONSTITUTION: Three elastic bodies 11d, 11e, and 11f are formed on a flat-plate material 10a of a permanently elastic metal and a deflection mass 13 is fixed to the upper surface of the tip of each elastic body. Each elastic body is vibrated in X direction by piezoelectric elements 14 and 15 but the vibration phases in ±X direction are opposite between the elastic bodies 11d and 11e at both sides and the elastic body 11f at a center. Coriolis force in opposite phase in Y direction is operated on the elastic bodies 11d and 11e at both sides and the elastic body 11f at the center. Coriolis force is operated on a position which is deflected from a center axis due to the deflection mass 13, thus enabling the elastic bodies 11d and 11e at both sides and the elastic body 11f at the center to be subjected to bending vibration in the phase in opposite direction to Z direction.  The vibration is detected by piezoelectric elements 16 and 16a, thus detecting the angular velocity in a rotary system in parallel to a plate surface.
