Abstract: PURPOSE:To reduce the fluctuation of pressure between the peak of positive pressure and negative pressure by providing a communicating pressure path between a slider plane at an upper side and a lower side than the tip part of a head chip in the rotating direction of a magnetic disk on a slider. CONSTITUTION:A floating head mechanism 11 is provided with the slider 14 having a cylindrical plane shape slider plane 13 for the rotating direction of the magnetic disk 12 and a magnetic head 15 mounted on the slider and in which the tip part of the head chip 15a is located nearly in the center part of the slider plane 13 in the rotating direction of the magnetic disk. On the slider 14, a pressure path 16 which communicates the slider plane 13 at the upper side and the slider plane 13 at the lower side than the tip part of the head chip 15a in the rotating direction of the magnetic disk is formed. And when the disk 12 is rotated at high speed, a part of pressure applied on the upper side is released to the path 16, then it is applied on lower side, which decreases operating pressure on the upper side, and increases the operating pressure on the lower side.

Title: Code reader
Inventor: UEDA NAOTOSHI
IPC: G06K7/10
Filed: 1991-10-21
Abstract: PURPOSE:To provide the code reader improved so as to exactly perform targeting to a code even for an operator with the low degree of skill by providing a beam generating means for projecting a target mark. CONSTITUTION:Since a code reader 1 is gripped by a hand, distance between a code reader 1 and a code M is indefinite but changed between about 5cm and 40cm every time. Since a light beam to irradiate target marks L1-L4 is parallel to a code reading optical axis A, therefore, position relation between the code reading optical axis A and the target marks L1-L4 is kept constant. When the code reader 1 is turned so as to irradiate the target marks L1-L4 near the code M, the code reading optical axis A almost crosses the center of the code M regardless of the distance between the code reader 1 and the code M. Namely, the exact target can be easily provided. Further, when the target marks L1-L4 are irradiated with four surface beams B1-B4 combined so as to be cross-sectionally crossed, the square-CALRA code M is easily targeted.

Title: Drive control device for door closer device
Inventor: HIROTA KOICHI
IPC: E05B83/36
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of noise at the time of operating a closer mechanism by controlling a driving mechanism with a control means so that the driving speed of the driving mechanism coincide with the preset target speed at the time of resetting a closer mechanism. SOLUTION: When a recognition that a closer mechanism is not positioned at the original position and that a door of a vehicle is perfectly closed is performed, a timer circuit 56 sends the driving signal to a reverse circuit 52. During the reset operation waiting time by the timer circuit 56, a power source monitor circuit 57 reads the voltage of a power source 6, and an initial pulse duration corresponding to the target rotating speed of a motor 41 and the read voltage is set on the basis of a map stored in a memory inside of a CPU 51. The target rotating speed of the motor 41 is set at a speed lower than the speed of the motor 41 during the closing operation, and the initial pulse duration is set at a pulse duration capable of obtaining the target rotating speed of the motor 41 with the voltage read during the reset operation waiting time.  With this structure, the driving noise at the time of reset operation is restricted to a nearly constant little noise in comparison with the driving noise at the time of closing operation, and the generation of noise at the time of operating a closer mechanism can be lowered.

Title: Disk brake rotor
Inventor: ICHIKAWA SHIGERU
IPC: F16D65/12
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To suppress squeaking and to maintain necessary corrosion resistance by forming a resin layer on at least the friction surface of the surface of a disk brake rotor. SOLUTION: Since a resin layer 7 is formed on the surface of a rotor 1 by coating, a thickness necessary for rust prevention is formed, and rust generated in the rotor 1 is prevented. If a method is for impregnating a resin on a sintered body, the formation of a film having a necessary thickness is difficult, and thus a rust preventing effect is not enough. Also, since the resin layer 7 on the surface of the rotor 1 contains no metal such as zinc showing adhesion, when the rotor 1 is rotated during braking while a pad 2 is pressed to the rotor 1, a phenomenon is prevented where transfer to the porous surface of the zinc pad 2 of the rotor surface causes adhesion between the zinc of the rotor surface and the zinc of the pad surface, and consequently a friction coefficient μ is increased. Thus, the phenomenon of squeaking during the initial use of a brake is suppressed.  Also, corrosion resistance and squeaking resistance are provided at the same time.

Abstract: PURPOSE:To widely shorten a release operating time and to attain the protecting of necessary data by transferring and saving the data in a memory to other normal exchange at the time of detecting an abnormal situation generation and after the release, storing the data into the memory. CONSTITUTION:At the time of the generation of fire, etc., a temperature detecting device 7 detects a peripheral abnormal high temperature and informs a control device 8. The control device 6 first occupies all leased lines 3 and diagnoses whether or not a transferring destination exchange is normal. When it is confirmed to be normal, a changing-over device 6 is controlled, a data memory 2 is connected to the released lines 3, and thereafter, the data in the memory 2 are transferred. At the receiving side, after the data are received by a receiving data processor 5 once, the control part 8 stores the data into the memory 2. At this time, the device 5 stores only the number of a transmitting side exchange and displays, to an indicator panel 9, that the data transfer is executed and informs of it. Thus, the data saved at the memory 2 are read through a data output interface 10 at the time of the release work of the transmitting side exchange and stored into the memory 2 at the released transmitting side.
