Title: Super abrasive grain grinding wheel
Inventor: TAKEUCHI TSUTOMU
IPC: B24D3/00
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To maintain the abrasive grain holding force, and to maintain excellent abrasive grain performance by specifying the coated amount of the abrasive grains of a super abrasive grains grinding wheel used for constant pressurization type double head grinding at a specified velocity of grinding wheel, at a specified ratio. SOLUTION: An abrasive grain layer, which is formed of diamond super abrasive grains 13 and resin bond 14, is fixed to a surface of a disc-shaped base of cast material. At the time of grinding work at 100 m/min of velocity of a grinding wheel at the most outside thereof, which is remarkably lower in comparison with a general grinding wheel, mechanical impact for generating the loose-out of the abrasive grains is small, and the abrasive grains, which are worn and flattened, is not fallen, and lowering of the grinding performance is easy to be generated. At this stage, quantity of nickel coating 15 in relation to the whole of weight of the abrasive grains 13, which includes the coating material, is set at 15-35%.  With this composition, the abrasive grains 13 fall at a stage that a sharp part of the tip of the abrasive grains 13 are worn and flattened, and a new abrasive grain 13 appear. As a result, excellent grinding performance can be maintained.

Abstract: PURPOSE:To prevent the deterioration of the performance of a group wick due to the seizing of processing oil and improve a limit heat transporting amount as well as a heat transfer rate by a method wherein the inner surface of a heat pipe is provided with a multitude of groups of longitudinal grooves axially while one part of the projections of said grooves is notched so as to be communicated with neighboring grooves. CONSTITUTION:The inner surface of a heat pipe 1 is provided with a multitude of the groups 2 of longitudinal grooves axially while one part of the projections of the groups is notched to form a multitude of notches 8 longitudinally so as to be communicated with neighboring grooves 9 through the noches 8. The flow of operating liquid can be smoothed by forming the notches formed on the groups rather in random. On the other hand, the notched part has communicated the neighboring grooves with each other to permit the communication of the operating liquid whereby the operating liquid flows into other grooves through the notched parts and returns into the initial groove while avoiding a part whereat the flow of the liquid is precluded thereby supplying the necessary amount of operating liquid into the grooves of respective evaporating section even when grooves, in which the flow of liquid is precluded due to the seizing of oil, are produced locally. Accordingly, the deterioration or variability of a limit heat transporting amount can be eliminated.

Title: Refining of pitch
Inventor: SAGA MITSUO
IPC: C10B57/04
Filed: 1983-10-17
Abstract: PURPOSE:To refine crude pitch at a low cost and obtain high-purity pitch having a residual ash content smaller than a specified value, by heating crude pitch to a specified temp. under slow agitation to cause formation of an anisotropic phase in an amt. larger than a specified value and separating the formed anisotropic phase.

Title: Suspension for magnetic disk
Inventor: HIRATA ICHIRO
IPC: G11B21/21
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To prevent generation of off-tracking due to a head slip without lowering track efficiency of a head by forming a recessed part having a larger curvature than a radius of curvature of a pivot part at a contact position of a gimbal where the gimbal comes in contact with the pivot part at a leading end of a load beam. SOLUTION: A pivot part 1 at a leading end of a load beam 11 presses a gimbal tongue part 7 of a gimbal 5. A recessed part 2 having a larger curvature than a radius of curvature of the pivot part 1 is formed at a position of the gimbal 5 where the gimbal 5 comes in touch with the pivot part 1. Since a contact area is increased in comparison with a conventional one where the gimbal comes in touch with the pivot part on plane, an average contact pressure generated within a contact circle of the pivot part is decreased. Moreover, the pivot part is retained in the recessed part without popping out of the recessed part because of the insufficiency to counteract a positional energy of the recessed part. Off-tracking because of a head slip is accordingly prevented.

This loop antenna 16 is constituted of, for example, a cable, and the both edges of this loop are connected with the control part of a read/write unit. Thus, when an entering and leaving person on which a non-contact IC card is mounted like a name card passes, an antenna in the non-contact IC card and the loop face of the loop antenna 16 can be turned into a state that they are present on the same plane. Therefore, the transmission of energy and information can be surely attained as long as the entering and leaving person does not pass through the door frame 15 at an extremely high speed.

Abstract: PURPOSE:To correct picture information by using a drive means to light up a light source in a duty of (drive period shorter than an optical response time of a read sensor and nearly stray luminous quantity)/(white reference board reflecting luminous quantity and stray luminous quantity) allowing the read sensor to read a reflected light from a reflecting face of a roller. CONSTITUTION:While an original 8 is not carried, a light source 6 is lighted and a light is emitted to a reflecting face of a roller 7. In this case, the pulse lighting condition of the light source 6 is set equal to a duty factor when a stray luminous quantity on a reflected face of the roller 7 is read in advance. Moreover, a drive frequency (f) is set to be f¦1/t, where (t) is a radiation time when a read sensor reads a signal by one line. The signal of the same quantity as the stray light component included in the sensor output at original reading is attained and the signal is inputted to a noninverting terminal of a differential amplifier 30. Since the amplifier 30 acts as a buffer amplifier, signals from sensors S1-Sn are fed sequentially to a memory 201, in which the signal is stored as stray light correction information.
