Title: Bidirectional optical transmitter
Inventor: TABUCHI HARUHIKO
IPC: H04B10/2507
Filed: 1991-03-19
Abstract: PURPOSE:To provide an optical transmitter capable of the high-speed transmission of an optical signal in bidirection without switching transmission/reception as well as modulation/demodulation means. CONSTITUTION:The connection is performed by an optical semiconductor 12 divided into a laser area 12A and a photoelectric conversion area 12B, an optical semiconductor 32 divided into a laser area 32A and a photoelectric conversion area 32B, and an optical fiber 52. In the case of transmitting the optical signal from the optical semiconductor 12 to the optical semiconductor 32, the laser beam is emitted in the laser area 12A in the optical semiconductor 12 and the voltage application by a voltage means 20 makes 0 to ensure that laser beam is not absorbed from the photoelectric conversion area 12B. In the optical semiconductor 32, the inverse bias voltage is not applied by the voltage means 40 and the optical signal is not received from the photoelectric conversion area 32B, and laser oscillation in the laser area 32A is stopped.

CONSTITUTION:On a semiconductor substrate 11 on which a lower layer wiring 12 is formed, an interlayer insulating film is formed so as to constitute a plasma silicon oxide film as a lower layer and a polyimide resin film 14 as an upper layer. Photo resist 15 is spread as a flattening sacrificial film. At a through-hole forming position, an aperture 16 is formed in the photo resist 15. The whole surface of the photo resist 15 and the polyimide resin film 14 is etched back. The polyimide resin film 14 is used as a mask, and the silicon oxide film is etched, thereby completing a through-hole 17. An upper layer wiring 18 to be connected with the lower layer wiring 12 via the through-hole 17 is formed on the interlayer insulating film. By this constitution, the step-cut of the upper layer wiring can be prevented, and working precision and yield can be improved.

Title: Control method for water heater
Inventor: KATO SHOZO
IPC: F24H9/20
Filed: 1985-03-19
Abstract: PURPOSE:To improve the safety by controlling the hot water temperature on the outlet side of the heat exchanger in a certain range close to the set temperature by controlling the selectible calorific value and the flow rate which is adjustable in a certain range. CONSTITUTION:The water which is adjusted in its flow rate by a flow rate adjusting means in the water circuit is supplied to and heated in the water heater 4.

If the water flow rate in the water circuit becomes lower than the first set flow rate (minimum flow rate, for example), and the hot water temperature becomes lower than the set temperature by a certain degree in spite of the afore-said flow rate control, the heating capacity of the heating device 1 is increased. On the other hand, if the flow rate in the water circuit becomes higher than the second flow rate setting (maximum flow rate, for example) which is higher than the first flow rate setting, and the hot water temperature becomes higher than the set temperature by a certain degree, the heating capacity of the heating device 1 is reduced.

Title: Magnetic recording medium
Inventor: WAKAI KUNIO
IPC: G11B5/706
Filed: 1985-03-19
Abstract: PURPOSE:To improve the traveling property and abrasion resistance of the titled medium by providing a ferromagnetic metallic thin film layer whose atomic ratios of cobalt to iron and iron to oxygen are regulated in the specified ratio on a substrate, respectively. CONSTITUTION:A ferromagnetic metallic thin film is formed on a substrate. In the composition of the thin film layer, the atomic ratio of iron to cobalt (Fe/Co) is regulated to 0.1-1 and the atomic ratio of oxygen to iron plus cobalt [O/(Fe+Co)] is controlled to 0.05-0.5. When the amt. of iron atoms is too small, the aging change in the friction coefficient is not sufficiently reduced and the traveling property is not satisfactorily improved. Conversely, when the amt. of cobalt atoms is too small, the excellent magnetic anisotropy of the crystal is not obtained, a stable and high-coercive force ferromagnetic metallic thin film layer is not obtained and the abrasion resistance is not sufficiently improved. When the content of oxygen atoms in the ferromagnetic metallic thin film layer is too small, the abrasion resistance is not improved enough and conversely the oxide film is hardened, when the content is too large. Consequently, the ferromagnetic metallic thin film layer is made brittle and the abrasion resistance is deteriorated.

IPC: G11B7/24
Filed: 1988-03-11
Abstract: PURPOSE:To perform the writing and reading of data by a compact recording apparatus unnecessary to take a hollow structure, by containing a photosensitive silver salt, a reducing agent and a heat converting material in a recording medium. CONSTITUTION:An optical recording medium may contain a photosensitive silver salt, a reducing agent and a heat converting material in the same layer or in different layers. Especially, in an aspect of regeneration and durability, since the dry silver salt is unstable to heat, for example, a layer (HDS layer) having the thermally developable dry silver salt and a heat converting material layer (HM layer) may be provided in an adjacent state or through an intermediate layer. The HM layer is necessary not only for playing a role converting light to heat energy but also for performing reading and tracking control by the reflection of light. As a material for satisfying these demands, there is an inorg. metal or org. dye already used in a DRAW medium and a material absorbing and reflecting laser beam corresponding to reading light may be used.
