Title: Thin film magnetic head
Inventor: NAITO KANICHI
IPC: G11B5/31
Filed: 1986-06-03
Abstract: PURPOSE:To realize a thin film magnetic head with excellent recording efficiency and long service life by placing a tip of a gap toward a coil from a cross point (the cross point inclusive) between a prolonged line of a magnetic layer along the slope of a gap forming part and the prolonged line of the gap. CONSTITUTION:A base end A of a magnetic layer 5 is placed at the cross point between the extension of a slope aa' of a contact part 5a and the surface of a magnetic base 2. If the position of the base end A is toward the coil 4 from the said position, the magnetic resistance is increased, the magnetic characteristic is lowered and if the position is apart from the coil 4, its shape is enlarged. Further, a tip B of the gap 6 is placed at the cross point between the extension of a slope bb' of a gap forming part 5b and the gap line. In this case, the gap depth is a length (d) (=BB') as shown in figure. In forming the gap depth to be the length (d) or below, the tip of the gap 6 is saturated magnetically, the recording efficiency is excellent, while the gap depth is formed to be in excess of the depth (d), the tip of the gap 6 is not saturated magnetically and the recording efficiency is low.

Abstract: PURPOSE:To cope easily with the reconstitution and the extension of the function of a message processing system by forming a message processing part with a message processing unit and making the processing unit take share of the message given from a message producing terminal. CONSTITUTION:The message processing part 10 consists of the message processing units 11a-11h. These units are made exclusive to correspond to the attributes of the messages to be processed at every unit. Each unit judges via interface control parts 13a-13h and a bus 5 whether the message should be processed by own unit. If the message is judged to be processed by own unit, the corresponding unit performs the processing. Then the unit stores the processing result and the corresponding message in a link to the memory area of a message memory part 4. The output distribution control part 21ab of an input/output distribution control part 2a sets the completion of the output and then updates a transaction file.

Accordingly, the absolute temperature of the temperature detection windings 3 and 4 is in proportion to the value of resistance, and the resistance value of the windings 3 and 4 can be measured. As a result, the temperature rise of the windings of the transformer can be detected in a highly precise and excellent responsive manner.

Title: Microstrip line antenna
Inventor: NISHIMURA SADAHIKO
IPC: H01Q13/08
Filed: 1978-10-16
Abstract: PURPOSE:To secure the enough reduction of the cross polarized wave component by providing a pair of crank-type strip conductors on the dielectric substrate in a linear symmetric way. CONSTITUTION:A pair of crank-type strip conductors 1a and 1b are provided on the surface of dielectric substrate 3 containing earth conductor 2 on the rear surface in a linear symmetric way. One end of each of the both crank-type lines is opened, and the other end is connected to feeding point S via power distributor 10. In such constitution, the current flowing instantaneously through Z-direction slice groups A2a, A3a...of conductor 1a and Z-direction slice groups A2b, A3b...of the other conductor 1b are all turned to the right and fixed. As a result, the electric fields are strengthened to each other to form the single beam. On the other hand, the current flowing through slices B1a, B1b and B2a plus B2b...are opposite to each other on the same axis, and thus no electric field exists. Accordingly, the composite field of the cross polarized wave component never appears within the E plane. Thus the cross polarized wave component can be reduced completely.

Abstract: PURPOSE:To improve the accuracy of a pulse signal generator using a relay by providing additionally a measuring means measuring a pulse time and a pulse time correcting means to a device in a dial pulse generator in a telephone exchange to correct automatically a meter rate of an output relay. CONSTITUTION:A theoretical value set in a theoretical value setting section 1 is inputted to a time setting section 2 together with a corrected value. Finally, an output relay is driven in a calibrated time and its state is measured by a measuring section 5. A period discriminating section 6 detects whether the measurement is the first or not and when the measurement is the 1st, an initial correcting value is introduced from an initial correcting value storage section 8 and fed to the time setting section 2. On the other hand, when the measurement is not the 1st, a correcting value calculating section 7 is activated. The correcting value calculating section 7 checks whether or not the absolute value (difference) of the theoretical value - measured value is within the permissible value, and when the value is within the permissible range, it is handled as it is as the correcting value, and when the value is at the outside of the permissible value and when the difference is large, a prescribed value is added/subtracted to/from the preceding correcting value to form the correcting value, and when the difference is small, a half of the absolute value (difference) of the theoretical value - measured value is added to the preceding correcting value to obtain the correcting value.

Title: Disk brake
Inventor: HORIBE OSAMU
IPC: F16F15/08
Filed: 1982-07-22
Abstract: PURPOSE:To strengthen the connection of metallic plates and a vibration-proof member by a method wherein the edge of the vibration-proof member is held clamped by the edges of the metallic plates whose edges are folded in the same direction. CONSTITUTION:When the pressure of a brake liquid is supplied into a cylinder 10, a piston 11 and a caliper 4 move vertically to thrust brake pads 7 and 6 against both side surfaces of a disk 18 to thereby brake the disk. The frictional heat generating at this time is released into the atmosphere from the surface of the disk 18 and transmitted to thin plates 13 and 12. The thin plates 12 and 13 reduce or prevent the generation of brake creakings as a result of deformation of the vibration-proof member 22 in the direction of the axis of the disk 18. The metallic plates 20 and 21 and the vibration- proof member 22 are bonded together in such a manner that the edge 22a of the member 22 is held clamped by the edges 20a and 21a of the metallic plates 20 and 21 whose edges are folded in the same direction. Therefore, the frictional heat is transmitted to the vibration-proof member and even when a torque in the rotational direction of the disk is applied on the member 22, it is possible to prevent the separation of the member 22 to thereby control effectively the lowering of the anti-vibration effect of the member 22.
