Title: Production of cylinder liner
Inventor: MASUDA RYUICHI
IPC: B22D25/02
Filed: 1985-02-28
Abstract: PURPOSE:To form easily a cylinder liner having high performance by immersing a metallic mold into the melt of an SiAl alloy and forming a solidified layer on the outside periphery of the mold to a prescribed thickness then pulling up the mold. CONSTITUTION:The molten high-SiAl alloy 2 put into a holding furnace 1 for the molten metal is maintained at a prescribed temp. and the metallic mold 3 is immersed for the prescribed length into the molten metal 2. While the inside of the mold 3 is kept cooled by a cooling liquid 9, the mold is kept immersed in the metal 2, then the mold 3 is formed of the same alloy and has good heat conductivity and therefore the metal 2 in contact with the peripheral side face of the mold 3 is cooled and sticks to the outside periphery of the mold 3 in the form of a crystal, thus forming a high-SiAl alloy layer 10. The molten high-SiAl alloy metal layer 10 having the desired uniform thickness is obtd. When the mold 3 is pulled up from the metal 2. Since a heat insulating material 8 is attached to the lower part at the bottom end, said part is not cooled by the liquid 9 and the alloy layer 10 is not formed on the material 8. The alloy layer 10 is thus made cylindrical.

Title: Production of dichroic filter
Inventor: YAMATAKA SHUICHI
IPC: G02B5/28
Filed: 1993-03-01
Abstract: PURPOSE:To decrease strain generated by coating of a dichroic coating film on a glass substrate and to obtain high accuracy of flatness at a low cost by subjecting the substrate to treatment to remove stress such as ultrasonic vibration or heat treatment by heating and cooling. CONSTITUTION:The dichroic filter 1 consists of a glass substrate 2 and a dichroic coating film which selectively reflects light of specified wavelength and is formed on the one surface of the substrate. This coating film 3 is a multilayer interference film comprising dielectric films, for example, produced by alternately laminating TiO2 and SiO2 by vapor deposition to about 30 layers. During forming the coating film 3, the dichroic filter 1 generates strain shown as dash lines in the figure due to the inner stress of the coating film 3. The strain thus generated is removed by heat treatment or ultrasonic vibration to remove stress so that deformation is decreased to increase accuracy of flatness. Thereby, the imaging performance of an optical system using the dichroic filter can be easily improved.

Then the values of the compensation signals are successively changed and at the same time compared with a reference level by a comparator 7 for detection of them. Thus the variation with time and the temperature characteristics can be compensated with no increase of circuit elements nor need for the initial control of a magnetic disk device. As a result, a satisfactory settling action is possible right after a head seeking state. Then a compact magnetic disk device is obtained together with the high capacity and high speed.

Title: Permeable erosion control dam
Inventor: WAKAMATSU SEIJI
IPC: E02B7/02
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To enable an economic design of a dam body and facilitate exchange of a damaged buffer means by detachably attaching a buffer means to absorb impulse energy of large gravels in a flood to the upstream face of a dam body. SOLUTION: A buffer means 14 is attached to the upstream face of a dam body detachably from the dam body to absorb impulse energy of large gravels in a flood. That is, the buffer means is detachably attached to the front face of a column member 6A through brackets 15 with bolts 16 in the upstream side of the dam body M. When a large gravel hits on the buffer means 14, the buffer means 14 is dented and deformed and hence, the impulse which the dam body has suffered because of collision of a large gravel in a flood is absorbed by the buffer means 14 to mitigate the external force which the dam body will suffer. Accordingly, an economical design of the dam body can be realized and the damaged buffer means can be easily exchanged.

Abstract: PROBLEM TO BE SOLVED: To obtain portable radio terminal equipment by which the voice of the opposite party is heard even when an ear is separated from an ear speaker by transmitting received call voice from a loudspeaker when the loudspeaker is drawn-out from the case of the terminal equipment. SOLUTION: When a user judges necessity to make a call while viewing a screen, the loudspeaker 14 at the rear side of the ear speaker 11 is turned and taken out to the left side of the case. When the loudspeaker 14 is taken-out, a control part 8 detects that the speaker 14 is taken-out by the output of a draw-out detector 17 and connects a change-over switch 16 to the loudspeaker 14. Thus, the voice of the opposite party is taken-out from the loudspeaker 14 in a large volume by way of the change-over switch 16 and an amplifier 15 from a voice part 7. Then the user can hear the call of the opposite party without putting his or her ear on the ear speaker 13.
