Title: Fuel injection timing controller
Inventor: YAMAGUCHI SUSUMU
IPC: F02D41/14
Filed: 1984-06-07
Abstract: PURPOSE:To prevent increase of cylinder pressure of Diesel engine effectively thus to lengthen the service life of engine by rising the temperature of working oil in a hydraulic timer upon droppage of the temperature conditions at the start of engine below predetermined level and bringing said timer into the condition having the most delayed angle. CONSTITUTION:The most lagged angle control through second control data D2 will start upon droppage of the temperature of control unit below predetermined level at starting. Upon provision of second detection signal DSs after elapsing predetermined time T0, third control data D3 is produced in place of the data D2 to control the solenoid valves 5, 7 on the basis of said data D3. Then supply of engine oil 11 pressurized through a hydraulic pump 9 and warmed through operation during the time interval T0 to a timer 4 will start where the temperature of engine oil will rise as the time elapses to lower the viscosity to bring the lag angle control through a hydraulic timer to the most lagged angle as the time elapses. Consequently, the increases of the engine cylinder pressure is prevented to lengthen the service life while to improve the engine starting performance.

Title: Magnetic head and magnetic storage device using the same
Inventor: TAKANO KOJI
IPC: G11B5/39
Filed: 1994-05-27
Abstract: PURPOSE:To obtain an MR head of a soft bias type with a narrow track width which prevents the direction of magnetization in an MR film and the direction of magnetization in a soft film from attaining the same polarity with respect to external magnetic fields, has a high sensitivity and is good in the linearity of reproduction response. CONSTITUTION:An antiferromagnetic film or permanent magnet film 5 is formed adjacently to the soft film 6 in the MR head having the MR film 8 and the soft film 6 and the magnetization of the soft film is subjected to exchange bonding. A soft magnetic film having a relatively high coercive force is otherwise is used as the soft film. The magnetization direction of the exchange bonded film 5 is set in a direction where bias magnetic fields are easily impressed on the MR element. As a result, the hysteresis curve of the soft film shifts by as much as the magnitude of the exchange bonding if the soft film is magnetically exchange bonded with the antiferromagnetic film or permanent magnet film and, therefore, the magnetic field to induce a magnetization change is made larger and the linearity within the operation region is assured.

Title: Profile crystal resonator
Inventor: YASUIKE RYOICHI
IPC: H03H9/19
Filed: 1989-05-09
Abstract: PURPOSE:To prevent the reduction in the resonance sharpness of a vibrator due to the portion left from etching by providing a support only to the side face toward -X of an X-cut crystal vibrator vibrated in the profile vibration mode. CONSTITUTION:An X-cut crystal vibrator in the profile vibration mode consists of a vibrator part 10, a support part 12 and a seat part 14, no support toward +X side causing the portion left from etching is not provided and the support part 12 is provided to the side toward -X side not causing any portion left from etching. Thus, even when etching leaves a position 16 on the side toward +X of the support part 12, no portion left from etching is caused to a part close to the vibrator 10. Thus, a high Q (resonance sharpness) is obtained without giving the effect of the portion left from etching caused due to the anisotropy of the crystal to the vibrator and the variance in the characteristic is reduced.

Title: Tape reel
Inventor: KAWAMURA SATOSHI
IPC: G11B23/087
Filed: 1995-05-15
Abstract: PURPOSE: To realize a high speed winding of tape in good order without disordered winding by setting the breadth dimension of the tape winding face of a tape winding shaft substantially wider than the breadth dimension between the inner surfaces of both reel flanges. CONSTITUTION: In the tape reel 1, a convex or concave chevronwise tape winding face 7 is formed on the outer circumferential surface of a tape winding shaft 3. Since a tape T is wound tightly on the convex or concave chevronwise tape winding face 7, the space between the tape T and the inner surfaces of upper and lower reel flanges 4, 5 can be widened substantially without altering the breadth dimension between the upper and lower reel flanges 4, 5 or the tape width. Consequently, air entrained at the time of a high speed winding of tape can be passed smoothly to the space. With such structure, air flows smoothly and the tape is wound while being arranged neatly.

Abstract: PROBLEM TO BE SOLVED: To reduce installing space for an actuator by using the same actuator both for traveling and loading/unloading work. SOLUTION: For traveling a truck main body 1, a horizontally moving base 5 is fixed to the truck main body 1. By making the shaft center of a driving steering wheel 6 to be roughly in parallel with that of a front wheel 2, the truck main body 1 is switched to a 'traveling mode'. In this condition, steering is performed while driving the driving steering wheel 6, and the truck main body 1 is traveled. For unloading a workpiece 5 on a fork 12, first the driving steering wheel 6 is stopped and a free caster 3 is locked. Then, the fixed horizontally moving base 5 is released. Then, for making the axial center of the driving steering wheel 6 roughly perpendicular to that of the front wheel 2, the driving steering wheel 6 is rotated by about 90 deg. around a vertical axis and switched to a 'loading mode'.  By rotating the driving steering wheel 6 in this condition, the horizontal moving base 5 is moved right. Followingly, the workpiece 5 is placed on the fork 12 protruded in the right direction.

Filed: 1995-05-16
Abstract: PURPOSE: To obtain a multilayered optical information medium in which the distance between an information plane near the incident side of laser light and an information plane far from the incident side of laser light is made uniform. CONSTITUTION: An adhesive layer 16 is formed between information planes in such a manner that particles 17 having the size the same as the distance between the information planes and the refractive index equal to that of the hardened adhesive layer 16 are mixed in the layer 16.
