Title: Preventing method for forgery of magnetic recording medium, and magnetic recording medium using the method
Inventor: SUZUKI HIDEO
IPC: B42D15/10
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To prevent a magnetic recording medium from alteration or forgery by forming a protective magnetic layer during the processes of coating, orienting and drying of a magnetic material so that regeneration of the orientation of the protective magnetic layer is made impossible by drying and solidifying the magnetic layer. SOLUTION: The magnetic layer 2 is formed by applying a magnetic recording material on the surface of a substrate 1 comprising a synthetic resin, paper, etc. A part of the magnetic layer 2 is magnetized by a writing device to record information to form a recorded part 2a. Before the magnetic layer 2 is dried, a protective magnetic layer 3 containing protective magnetic particles oriented in the different direction from the orientation of the magnetic particles in the magnetic layer 2 is formed in a different place from the recording part 2, for example, in the area where punch holes indicating the use state of the medium are to be formed. The protective layer 3 having the oriented protective magnetic particles has large magnetic hysteresis and large output, but the output is erased by punch holes and can not be read.  Thus, by forming the protective layer 3 before drying and then drying and solidifying, the orientation of the protective layer can not be regenerated after solidified. Therefore, the obtd. medium can not be easily altered or forged.

Filed: 1988-07-12
Abstract: PURPOSE:To easily manufacture a vibrator for high frequency by heating a piezo-electric body consisting of the rotary Y board of lithium niobate single crystal at a prescribed temperature for a prescribed time, generating a polarization inversion layer in a thickness direction and generating driving electrodes on facing main surfaces. CONSTITUTION:The rotary Y board wafer 21 is segmented from the lithium niobate single crystal. A polarization Ps is generated by the polling processing of the single crystal in the thickness direction of the wafer 21. Next, a polarization Ps' in a reverse direction with respect to the polarization Ps is generated in the wafer 21. The wafer 21 is inputted to a furnace which is pre-heated to 400 deg.C, and temperature in the furnace is raised at the rate of about 150 deg.C per hour so as to make it to 1130+ or -2 deg.C. The temperature is maintained for 80-100 hours and the temperature is dropped for about 400 deg.C over 30 minutes - one hour. The wafer 21 is taken out from the furnace and the inverse polarization Ps' which is in the reverse direction with respect to the polarization Ps whose thickness is half the wafer 21 is generated on the wafer 21. Here, a large number of driving electrodes 3 are generated on the upper and lower surfaces of the wafer 21 and the electrodes 3 are divided by using YAC laser.

Title: Method of correcting amount of injection of each cylinder of electronic control diesel engine
Inventor: TSUKAMOTO KEISUKE
IPC: F02B3/06
Filed: 1984-08-23
Abstract: PURPOSE:To highly accurately control an amount of injection by calculating variations of rotation of a cylinder from a difference between the lowest and highest rpms retrieved from engine rpm among set continuous crank angles for said cylinder, and thereby estimating rotation variations close to actual rotation variations. CONSTITUTION:In engine operation, first in ECU58, average engine rpm NE between 180 deg. CA are evaluated from an output of an engine sensor 22. Then, it is judged whether or not a state is more than two cylinders, in which state NE1 is a minimum value Nl among NE1-NE4 for the same cylinder number in the engine rpms NEi (i=1-4) at each 45 deg. CA while being subject to the engine being under an idle stable state. Judged it to be YES, the NE1 is determined to be the minimum rpm Nl, and in succession the maximum rpm is retrieved from rpms other than the NE1 and made to be Nh. Rotation variations for each explosion cylinder are detected from a difference between the above-described rpms Nh and Nl are detected, whereby an amount of correction of the injection amount is estimated to enable the injection amount to be highly accurately controlled.

Title: Automatic transmission
Inventor: IDOGUCHI MASARU
IPC: B60W10/10
Filed: 1985-08-11
Abstract: PURPOSE:To improve a starting characteristic as well as to eliminate a grating noise of gears, by disengaging the existing gear when a car speed goes down to below the specified value, while controlling an engine speed so as to become a synchronous speed, engaging a starting gear, and under this condition, making a clutch stand by without being engaged. CONSTITUTION:When a car speed comes to the specified value just before its stop, the existing gear is disengaged, controlling an engine speed so as to become a synchronous speed, and a starting gear is engaged, and under this condition, making a clutch 30 stand by without being engaged. Therefore, since a car starts with only engagement of the clutch 30, a starting characteristic is improved. Moreover, the engine speed is shifted to the starting gear with the synchronized speed so that a grating noise of gears is prevented from occurring. In addition, gear shifting to the starting gear takes place under the state of revolution, whereby any drag of a dog clutch is kept back.

The vibration of a specific frequency generated due to the pulsating torque generated from the main motor is detected by the sensors 16a, 16b, the detected signal is compared with the reference value set by a reference value level generator 20 by a comparator 19. A pattern generator 21 limits the rotary force of the main motor based on the compared result. Thus, the generation of a large vibration due to the excess pulsating torque or the pulsating torque can be suppressed.
