Title: Magnetic head
Inventor: AOTA YOSHIAKI
IPC: G11B5/02
Filed: 1990-08-10
Abstract: PURPOSE:To prevent the breakage of the recording surface of a magneto-optical disk even if the disk has the thermal deformation or is loaded with a tilt. CONSTITUTION:The projections 10a-10d are formed on a magnetically operating surface of a magnetic head 10 in response to the outside of an effective recording area a magneto-optical disk. That is, the projections 10a-10d are set outside an effective recording area 20 of the disk 1. At the same time, these projections are set at the height of 0.05-0.10mm from the magnetically operating surface of the head 10. As a result, the recording surface of the disk 1 abuts on those projections but never touches the head 10 even if the recording surface of the disk 1 gets close to the head 10 due to the thermal deformation or a loading fault of the disk 1. Thus the recording surface of the disk 1 is never broken.

Title: Fixing device
Inventor: YANO TAKAHIKO
IPC: G03G15/20
Filed: 1984-10-09
Abstract: PURPOSE:To prevent the extreme rise of temperature of a heat roll in case of the use of small-sized forms by arranging a radiating member having a high heat conductivity and bringing this member into contact with parts, which forms do not pass, of the peripheral surface of the heat roll or a pressuring roll. CONSTITUTION:A radiating roll 20 consisting of materials having a high heat conductivity is supported turnably by a shaft 21 and is so arranged that peripheral surfaces of large-diameter parts 20b of the radiating roll 20 are brought into contact with the peripheral surface near both ends in the axial direction of a pressuring roll 5. That is, when a small-sized form passes between a heat roll 1 and the pressuring roll 5, the temperature near both ends in the axial direction of the heat roll 1 which are not brought into contact with the form is raised, but the heat energy is transmitted directly to large-diameter parts 20b of the radiating roll 20 through the surface of the pressuring roll 5 and is radiated to the outside. Thus, the temperature near both ends of the heat roll is not extremely raised even if the small-sized form is used, and the degradation due to heat of the heat roll itself and the damage of peripheral parts by a fire are prevented.

Title: Supporting jig for semiconductor wafer
Inventor: NODA YASUMASA
IPC: H01L21/78
Filed: 1985-09-24
Abstract: PURPOSE:To realize a light-weight, small-size transporting system by a method wherein a middle layer is covered with an adhesive layer of paste whose adhesive force degrades under conditions different from the conditions the middle layer is under. CONSTITUTION:On a substrate 1, a middle layer 2 is formed and allowed to harden. An adhesive layer 3 is formed on the middle layer 2, and a semiconductor wafer 4 is pasted to the adhesive layer 3. The entirety is attached to a dicing unit for dicing. The semiconductor wafer 4 is completely cut when the dicing is so accomplished that a blade creates a dicing groove 5 deep enough to reach the middle layer 2. Thereafter, the semiconductor wafer 4 as supported by an assembling jig is transported to a mounting unit whereat all the semiconductor chips are installed on a lead frame. Exposure to UV rays or the like is accomplished for reducing the adhesive layer 3 in its adhesive force. Such a setup allows the semiconductor chips to be easily peeled off and to be sucked up with a very weak adsorbing force. Need for a heavy-weight flat ring is eliminated, which results in a light-weight transporting system.

Title: Alarming device of wear of clutch disk
Inventor: INOUE HIROSHI
IPC: F16D13/75
Filed: 1982-12-02
Abstract: PURPOSE:To inform a driver of the wear of clutch disk for thereby saving fuel consumption and at the same time preventing the occurrence of traffic accident, by comparing an actual engine rpm with a theoretical one computed with basis on a transmission ratio with a clutch disk in a normal condition, and by generating an alarm if a deviation of the two values takes place. CONSTITUTION:When a worn clutch disk slips excessively, a voltage corresponding to an actual velocity becomes lower than a voltage corresponding to a theoretical velocity obtained from an engine rpm and a transmission ratio. In this case, because an input voltage from a F/V conversion circuit 7 deviates from a preset value of wind comparators 8-11, outputs of these comparators 8-11 lower to a L level. Therefore, the output of NOR circuit 12 increases to a H level, and because the output of NOR circuit 19 being the H level, the output of AND circuit 13, thereby actuating an alarm circuit 20 to inform a driver of the wear of clutch disk. In this way, even an unskilled driver and the like can easily know the slip due to the wear of clutch disk.
