Title: Recording medium of optical disk
Inventor: HARA SHINJI
IPC: G11B7/24097
Filed: 1989-10-30
Abstract: PURPOSE:To improve portability and to enhance a memory capacity, access speed and transfer speed by embedding a ferromagnetic material into the slope of the through-hole of a case and forming a part of a hub of a soft magnetic material. CONSTITUTION:The optical disk 1 is housed into a disk-housing recess 21 of the case 2. The ring of the ferromagnetic material or magnetic powder is embedded near the circumference of the through-hole 23 of the case 2 and a part of the hub 12 is constituted of the soft magnetic material. The optical disk 1 is, therefore, attracted to the case 2 by magnetic force and is integrally fixed to the case 2 while the optical disk 1 is held housed in the case 2. The dislodgment of the disk from the case 2 is thus prevented. Since the case is opened on one side, the thickness of the case may be as small about 50% up the thickness of the disk. This recording medium is as thick as a card calculator and is convenient to carry.

IPC: H05K3/24
Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To supply an equal amount of solder to each pad without bridging, when forming spare solder on the narrow-pitch pad of a printed wiring board. SOLUTION: A protection sheet layer 3 is formed on the entire surface of a printed wiring board 1 having a narrow-pitch pad 2, the protective sheet layer 3 only on the pad 2 is removed, and the pad 2 is exposed. After a solder powder 4 coated with flux content has been coated thereon, an excess solder powder 4 adhered to a clearance of the pad 2 is removed, while the protective sheet layer 3 is peeled off. The coated solder powder 4 supplied on the pad 2 is heated and melted so as to form a solder layer 5. Thus, a desired equal amount of solder can be supplied without bridging.

IPC: G07F13/00
Filed: 1989-10-30
Abstract: PURPOSE:To always supply water cooled sufficiently as the dilution water of a drink in sale by circulating and sending the water with a pump between a water supply pipeline and a water reservoir via a water supply switching valve and a water circulating pipeline at the standby of sale. CONSTITUTION:The water supply switching valve 12 is formed, for example, in a three-way electromagnetic valve, and a port communicated to the water circulating pipeline 13 is closed in an ordinary operation, and a port communicated to a cooling water nozzle 4 is closed and a port communicated to a water circulating pipeline 13 side is opened with a command. At this time, the water stagnating in a pipeline at the downstream side of a water cooler 8 in a water supply pipeline 9 is returned to the water reservoir 1 via the water circulating pipeline 13 by operating a water supply pump 5 simultaneously, and the water cooled via the water cooler 8 is sent to the terminal of the water supply pipeline 9 instead of the water. Therefore, no water used as the dilution water stagnates in the pipeline for a long time by supplying the command to the three-way electromagnetic valve and the water supply pump at every cycle of constant time at the standby of sale. In such a way, the water sufficiently cooled can be always supplied from a cooling water nozzle as the dilution water in sale.
