Title: Generation apparatus on beach
Inventor: MASUBUCHI HIDEO
IPC: F03B13/18
Filed: 1983-11-30
Abstract: PURPOSE:To supply a large amount of electric power at a low cost by spreading a vinyl sheet which is wide as a whole and equipped with a number of bag parts directed in one direction and installing buoys and generators at the both edges of the vinyl sheet. CONSTITUTION:A pipe 4 having a generator 3 installed is arranged at the place where the wave dashes on beach, and said dashing wave flows mainly on a sheet and is introduced into a bag part 2, which is swelled to revolve the sheet. Although the underside of the sheet shifts in the opposite direction, the bag part does not swell, since the bag part is directed in the opposite direction, and the whole revolves only in one direction. When the wave retreats, the bag part on the underside swells, and the sheet continues the revolution in the same direction. Therefore, the revolution of the sheet revolves the generator 3 enveloped by buoys, and electric power is generated.

Title: Magnetic recording method for digital signal
Inventor: IZUMIDA MORIJI
IPC: G11B5/09
Filed: 1987-09-11
Abstract: PURPOSE:To reduce the error generation by emphasizing the low frequency component of a recording signal and recording it to a magnetic medium. CONSTITUTION:A digital signal inputted to an input terminal 1 is inputted to a low area emphasizing circuit 2 and a recording amplifier. At the low area emphasizing circuit 2, the signal component of a frequency or below corresponding to a maximum inversion interval is extracted by the low-pass filter of a cut-off frequency. An output signal 2a of the circuit and original input data 1a are added by an adder 3, and recorded to a magnetic tape 5 by a magnetic head 4. As such a result, the recording, in which the digital signal is made into a high frequency bias signal and a low frequency component is emphasized, can be realized. By minimizing a compensating quantity to a low frequency component at a reproducing circuit, a signal is reproduced without increasing the noise of the low frequency area, and the waveform deterioration can be reduced.

Title: Generation controlling device for hybrid vehicle
Inventor: IZUMIURA ATSUSHI
IPC: B60L50/16
Filed: 1999-08-10
Abstract: PROBLEM TO BE SOLVED: To make it possible to control generation load torque of a motor in accordance with the load at the idling revolutions by determining the limit value of the generation load torque of the motor, based on a load torque and an obtainable torque. SOLUTION: A generation controlling device calculates the load torque of an engine required for generating electric power used by a vehicle at the time of idling revolution of the engines (S9). It also calculates torque that can be generated at the idling of revolutions of the engines (S10). Based on each calculated value of the load torque and the obtainable torque, the limit value of the generation load torque of the motor is determined (S11, S12, S13). This makes it unnecessary to increase the number of the idling revolution of the engine and prevents the deterioration of fuel consumption rate even if the obtainable torque of the engine is decreased.

Title: Inherently antistatic thermoplastic polyamide-polyether film
Inventor: MAABIN AARU HEBUNSU
IPC: C08L77/02
Filed: 1991-09-06
Abstract: PURPOSE: To obtain a film which has particular antistatic characteristics and a degree of hydrophilicity suitable for wrapping electronic devices without the addition of an antistatic agent by incorporating a hydrophilic polyether block amide copolymer and a compatible polymer.  
     CONSTITUTION: A thermoplastic film is obtained by incorporating a hydrophilic polyether block amide copolymer and a compatible polymer, whereby, without the addition of an antistatic agent, the film has antistatic characteristics in accordance with the military specification test in that the film will dissipate 5,000 volts direct current in about 2,000 milliseconds or less and has a degree of hydrophilicity suitable for packaging electronic devices. The film is antistatic without requiring the addition of an antistatic agent thereto and yet does not have a hydrophilicity problem (which could cause corrosion of a circuit board wrapped therewith) due to the presence of the compatible polymer despite the presence of the hydrophilic polyether block amide copolymer.

Title: Grinding element of metal
Inventor: IBATA SACHIKO
IPC: B23D71/04
Filed: 1984-10-29
Abstract: PURPOSE:To obtain a grinding element possible with mass-production, excellent in durability and hard to be flattened even after working on a non-metallic work to be ground by constituting the element from a number of holes bored in a metal plate and a plurality of teeth in each hole protruded in the form of a beak by bending over right angle from the equal angle position around each hole. CONSTITUTION:When moved along the surface in contact so that teeth 4 contact the surface of an object to be ground, each group of teeth 4 opens as blossom, wherein each tooth 5 is equipped with a tip 6 and cutting edges 7 and the angle of cutting action alpha is an acute angle, so that grinding can be made with a minor force applied. Because each group 4 includes four teeth 5 equally divided circumferentially, it must not necessarily be applied to grinding in one specific direction. Because the splash produced stagnates in the hole 3 temporarily or is exhausted to opposite side therethrough, the group of teeth 4 is free from risk of being flattened, and further, provision of a hole 3 in the center of each group 4 allows expectation for good heat radiation to ensure that the teeth during service are well cooled. Thus, excellent durability is secured as well as losing the sharpness of the cutting edge is prevented, to contribute to enhancement of the grinding performance.

Title: Replaceable blade type cutter knife with cover guide
Inventor: KOBAYASHI KOJI
IPC: B26B1/08
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To prevent the blade of a cutter from being unpreparedly broken, make easy to add a force, and improve the workability by fitting a cover guide to the part of the exposed blade of a cutter knife so as to cover the back side of the blade of the cutter knife. SOLUTION: This replaceable blade type cutter knife 1 has a cover guide 10 about on the straight line passing the working point of the cutter. In use, a cutter blade 2 is set so as not to protrude from the cover guide 10. By forming the cover guide 10 in this way, the cutter blade 2 can be held and stabilized. Accordingly, the cutter blade 2 is strong to a horizontal force and hardly broken. Even if a force is added from above the straight line passing the working point of the cutter, the back part of the exposed replaceable blade is never directly pressed, and the damage of a finger can be thus prevented. The material of the cover guide 10 is not particularly limited, and the form or size thereof can be also optionally selected. The fixing method is not particularly limited except its fixing to the horizontal direction of the cutter blade 2.
