IPC: G01R33/02
Filed: 1987-06-12
Abstract: PURPOSE:To detect a magnetic field and magnetic flux, which are generated in a minute region highly sensitively, by winding an exciting coil, which generates a high frequency alternating magnetic field, and a regenerating coil, which detects the magnetic flux that is generated in the exciting coil, around a common magnetic core. CONSTITUTION:At the time of recording, an exciting-coil driving circuit 1 and a regenerating circuit 6 are turned OFF with a selecting signal. The thin film of a magnetic core 12 is magnetized with a writing circuit 8. The signal is recorded in a medium. At the time of regeneration, the writing circuit 8 is turned OFF, and the exciting-coil driving circuit 1 and the regenerating circuit 6 are operated. When a main magnetic pole 12a of a vertical head H is located at magnetic domains 14 in a vertically magnetized layer 13, the main magnetic pole 12a is magnetized. At this time, the magnetic core 12 is magnetized to a saturating state or the state close to the saturation. The outputs of the exciting coil 2 and the regenerating coil 5 become close to zero. When the main magnetic pole 12a is located at the intermediate part between the magnetic domains 14 in the vertically magnetized layer 13, the magnetic flux from the medium becomes effectively zero. The exciting coil 2 and the regenerating coils 5 are magnetically linked, and the output is obtained.

IPC: G01F1/28
Filed: 1984-07-16
Abstract: PURPOSE:To prevent an impulse wave due to a backfire from damaging a valve, etc., by attenuating the impulse wave due to the backfire in a communication path and sending it to a blade plate. CONSTITUTION:When impulse wave due to the backfire reaches the air flow meter, its pressure is transmitted to the blade plate 12 through communication paths 46, 47, 48, and 49, so it is attenuated in those communication paths 46, 47, 48, and 49 to operate on the blade plate 12. Therefore, the valve 42 is not fully closed instantaneously and the impulse wave passes through the opening part of the valve 2, so it is not applied to the entire surface of the valve 2 to eliminate the deformation of the valve 2, damage to a bearing 11, and collision and damage of the blade plate 12 to an adjusting screw 40.

Filed: 1989-06-09
Abstract: PURPOSE:To suppress the generation of block distortion low even when a picture border exists in a block by discriminating a dynamic range of a block and controlling the passing characteristic of a smoothing means in response to the result of discrimination. CONSTITUTION:A discrimination circuit 18 extracts information relating to a dynamic range from a code representing the maximum and minimum value of the input, compares the information with a prescribed threshold level and when the threshold level is exceeded, a switch 20 is thrown to a contact (a) (that is, output of a smoothing filter 14) and when the level is less than the threshold level, the switch 20 is thrown to the position of a contact (b) (that is, output of a delay circuit 16). Thus, the data is a data via smoothing filter processing in a block where block distortion takes place and the data is a data decoded by a block decoding circuit 12 in a block where no block distortion takes place.

Title: Emergency automatic braking device
Inventor: KAYANO MITSUO
IPC: G01S13/93
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To sufficiently maintain safety at the time of an emergency automatic brake operation. SOLUTION: An emergency automatic brake control means 3 judges whether to operate an emergency automatic brake on the basis of vehicle state data detected by a vehicle state detecting means 1 and travel environment data detected by a travel environment detecting means 2. In case of judging to operate the emergency automatic brake, an informing/operating timing control means 4 outputs a command to inform to that effect and then outputs a command to operate the emergency automatic brake at timing after the lapse of predetermined specified time. Upon such an occasion that the emergency automatic brake is to be operated, since the brake of a vehicle is applied after the effect is informed by an informing means 6, occupants including a driver can know in advance that the emergency automatic brake will be applied.  As a result, the occupants can calmly cope with strong inertia caused by the emergency automatic brake and stand on guard even in case of a collision. Damage can therefore be suppressed to a minimum.

Abstract: PURPOSE:To contrive the effective utilization of waste paper diaper by adding water to a mixture of pulp, water-absorbing polymer, etc., adding a polymer-solidifying agent to the mixture, finely crushing the obtained mixture together with a thermoplastic synthetic resin such as vinyl resin and using the crushed product as a reinforcing material. CONSTITUTION:Nonwoven cloth is mixed to a mixture of pulp and a polymeric water-absorbing agent such as pulp constituting the raw material of paper diaper and water is added to the obtained mixture to effect the active swelling of the polymeric waterabsorbing agent. A solidifying agent such as CaCl2 or MgSO4 is added in an amount of 0.1-15wt.% (based on the waterabsorbing agent) to the swollen polymeric water-absorbing agent to solidify the swollen agent. The non-uniform mixing state with other raw materials caused by the swelling of the agent can be eliminated by the above process. The solidified product is crushed to fine particles. Separately, a thermoplastic synthetic resin such as vinyl resin and rubber used as a packaging material for paper diaper is also crushed to fine particles. These particles are mixed to cement or silica raw material in an amount of 5-10% and kneaded with a required amount of water. The obtained mixture is formed, subjected to primary curing and finally cured at a high temperature in an autoclave. The polymeric water-absorbing agent or the thermoplastic synthetic resin can be utilized as a foaming agent in the above process to obtain the objective product at a low cost.
