Title: Optical head
Inventor: ANDO HIDEO
IPC: G11B11/10
Filed: 1989-12-22
Abstract: PURPOSE:To improve the reliability of a regeneration signal by setting the vibration direction of the light beam from a light source at a specific angle to the optical axis of a prism made of an anisotropic medium. CONSTITUTION:The slope of the vibration direction of the light beam that is emitted to a non-polarization beam splitting film 10 from the light source 2 is at almost 45 deg. to the optical axis of the anisotropic medium forming a prism member 4. Consequently, when a no-signal area on an information storage medium 12 is retrieved with the light beam, an ordinary and an extraordinary light beam become nearly equal in light intensity level on the photodetector 24. The reliability of the regenerative signal is therefore improved and the constitution of a signal processing circuit is simplified.

Title: Tacky adhesive sheet for body warmer, its housing bag and throw-away body warmer
Inventor: YAMANAKA EIJI
IPC: C09J7/02
Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To develop a tacky adhesive sheet for body warmers which allows dealing with differences in material, knitting, or the like, with one kind of the body warmers, exhibits good adhesive force even in readhesion by resticking, does not therefore require the assortment of a wide variety and diversified kinds of the body warmers corresponding to the differences in material, knitting, or the like, and allows the formation of the throw-away body warmers not requiring the selective use by each of the body warmers. SOLUTION: This tacky adhesive sheet for body warmers is a tacky adhesive sheet used for formation of the throw-away body warmers and is formed by having >=2 layers of tacky adhesive layers (21, 22 and 23) laminated in a thickness direction on one surface of a sheet base material (1) and separating these tacky adhesive layer via separators (31 and 32). A housing bag is formed by adhering the tacky adhesive sheet for body warmers temporally covered with the tacky adhesive layers by the separators and the air permeable base material to a bag form. This throw-away body warmer is formed by housing an air permeable exothermic composition within such housing bag. Accordingly, many stages of the tacky adhesive layers may be made to share their roles by the selective use of the respective tacky adhesive layers and the selection of the tacky adhesive surfaces by a block calender system via the separators is made possible.

Title: Controller for hot water supply apparatus
Inventor: YUNO HIDEYO
IPC: F24H1/00
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To prevent the set hot water temperature from fluctuating in apart ment house by providing a switch for setting/limiting the self control rate of gas consumption for the entire building and performing an arbitrary self control operation when the switch is turned on thereby controlling total gas consumption of an apparatus. SOLUTION: When hot water supply apparatus are installed entirely in an apartment house where the gas piping is thin and gas supply to gas apparatus is insufficient, the quantity of gas suppliable to each house is determined from gas supply to the apartment house. A self control rate is set by a total gas consumption limit switch 1 such that the hot water temperature does not fluctuate even when all houses are operating simultaneously. When the switch 1 is turned on, the control section of an apparatus receiving an on signal limits gas consumption of a hot water supply apparatus while monitoring a preprogrammed arbitrary self control operation not to exceed a set self control rate thus preventing fluctuation of set hot water temperature and eliminating inconvenience in use.

IPC: H04M3/00
Filed: 1990-11-29
Abstract: PURPOSE:To enhance the transmission quality of a voice signal by sending an analog signal through the same transmission capacity as that of two channels used by a digital subscriber circuit. CONSTITUTION:A voice band of a 13-bit CODEC (CODEC) C1 of an analog subscriber circuit is selected to be 3.4kHz, which is the same as that of a conventional 8-bit CODEC, and a dynamic range in the band is enhanced by using 16-bits per sample with respect to 8kHz sampling. Moreover, the 16-bit CODEC C1 requires a transmission capacity of 16-bit X 8kHz and divided into two of 8-bit X 8kHz per one channel and outputted to a data highway (DHW). That is, the 16-bit CODEC C1 uses a 8kHz clock signal to sample a voice band signal and uses a highway clock signal to use two channels of an 8-bit X 8kHz band. Thus, the quality of the analog subscriber circuit is improved.
