Title: Optical disk and manufacture of the same
Inventor: YAMATSU HISAYUKI
IPC: G11B7/24085
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To provide the optical disk with high recording density including shorter pits then 0.40 μm in length and having a ratio of the shortest pit width to the logest pit width to be >=0.8 and to provide the method for manufacturing the optical disk. SOLUTION: By utilizing such a fact that a pit width A as seen from the side of reflection film 20 of the optical disk is decreased narrower than a pit width B as seen from the side of a disk substrate 10 when the reflection film is formed on the side of the reflection film 20 by this film thickness, amt., a generally wider pit train than the optimum pit width as seen from the side of the disk substrate 10 is formed on a master disk by aligning with a laser having a wavelength of >=350 nm. The reflection film 20 is formed on the pit train transferred from this master disk onto the disk substrate 10, so as to make the pit width capable of minimizing interference between pits and a jitter of a regenerative RF signal. The signal is read out not from the side of the disk substrate 10 but from the side of the reflection film 20 (i.e., on the side of a light transmission layer 30).

Title: Radiant tube
Inventor: KOIDE KAZUNARI
IPC: F23D14/12
Filed: 1985-05-28
Abstract: PURPOSE:To prevent the cracking of the tip part of an outer tube by hot air from a burner, by providing a ceramic cap so as to face the tip of an inner tube in the tip part of a single-end type outer tube. CONSTITUTION:A ceramic cap 6 is provided in a closed tip part 2a of an outer tube 2 as required through an inorganic bonding agent. The cap 6 is made of ceramics such as a refractory material of, e.g., silicon carbide, whose thermal shock resistance is excellent. Hot air yielded in a burner 4 flows in an inner tube 3 and goes out of a tip 3a of the inner tube 3. At this time, the temperature in the vicinity of the tip 3a becomes very high. Since a closed tip part 2a of an outer tube 2 is protected from the hot air by the cap 6, the temperature rise can be suppressed to the maximum extent, and cracks are not yielded in the closed tip part 2a.

Title: Data transfer circuit
Inventor: TANAKA HISAYOSHI
IPC: G06F9/30
Filed: 1990-04-27
Abstract: PURPOSE:To transfer data between a RAM and a register in one machine cycle by constituting the register with a register for upper-bit data and a register for lower-bit register and simultaneously selecting two RAMs of plural divided RAMs and transferring data through two data busses independent of each other. CONSTITUTION:A register 100 consists of a register 101 for upper 8 bits and a register 102 for lower 8 bits. In the cycle of data transfer from the register 100 to RAMs 301 and 302, a control signal CONT1 is set to the high level. Consequently, a multiplexer 202 selects data on a base bus DB2 and outputs it to the RAM 302. The register 101 puts upper-bit data on a bus DB1 to write it in the RAM 301. Since NOR circuits 401 and 402 mask an address A0, RAMs 301 and 302 are simultaneously selected, and the same addresses A1 to AX are designated. Thus, data transfer is completed in one machine cycle.

Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To suppress smaller the loss of the oxide magnetic material used mainly for the transformer core of a switching power source, when it is used at high frequencies above 100 kHz. SOLUTION: To MnZn ferrite consisting principally of 50 to 56 mol% Fe2O3, 3 to 25 mol% ZnO, and MnO as the remainder, 0.02 to 0.1 wt.% CaO, 0.002 to 0.05 wt.% SiO2, 0.005 to 0.1 wt.% ZrO2, and 0.005 to 0.05 wt.% NaO are added as accessory ingredients. Consequently, while Zr ions distribute a glassy phase narrowly with thigh density nearby grain boundaries, Na ions are made to diffuse the glassy phase uniformly by lowering the fusion point of the glassy phase. Then the core loss is greatly decreased by the composite effect of the both.

Filed: 1990-04-27
Abstract: PURPOSE:To prevent the contamination of a periphery by toner by providing an exhaust part for making compressed air generated inside a toner supply device at the time of loading a toner cartridge escape on either of the toner cartridge and the toner supply device. CONSTITUTION:When the cartridge 1 is loaded in the toner supply device 2, the seal 8 of the aperture 7 of the cartridge 1 is peeled off by a projection 22 and pushed into a 2nd chamber 10 positioned outside a side wall 3.
