摘要:
The watch design creating system according to the present invention utilizes, for example, the internet as an information communication network. For example, a consumer (1) in subscribers (1 to N) which are customers, requests design information to a host computer (H) of the watch maker which is a watch supplier, through the internet, the watch maker provides, for example, a CD-ROM stored design software and data used for original design to the consumer. The consumer creates the original design watch in accordance with steps stored in the CD-ROM, records it into a FD (floppy disk) and sends it to the watch maker. The watch maker produces the original watch and delivers the completed watch to the consumer (FIG. 1).

In a method of manufacturing a semiconductor optical waveguide array in an ultra-high integration, the device yield per wafer is considerably increased and uniform and improved characteristics are obtained. In this method, there is manufactured a semiconductor optical waveguide array including a plurality of optical waveguides in an array structure in stripe-shaped growth regions enclosed by dielectric thin films on a substrate. The waveguides are fabricated through a selective crystal growth process and include a semiconductor multilayer structure including a quantum well layer or a semiconductor multilayer structure including a bulk layer. Namely, there is formed a plurality of stripe-shaped growth regions elongated parallel to each other, the regions being enclosed with a dielectric thin film. In each growth region, a semiconductor multilayer structure is selectively grown by metallo-organic vapor phase epitaxy (MOVPE). In the selective growth, the growth regions are parallel to each other with an interval therebetween, the interval being less than a diffusion length of a source material in a reactive tube during the crystal growth. Assuming that the dielectric thin film arranged between the respective growth regions has a width Wa and a first outer-most dielectric thin film and a second outer-most dielectric thin film arranged respectively outside of outer-most ones of the growth regions respectively have widths Wm1 and Wm2, there is satisfied a relationship of Wm1>Wa and Wm2>Wa.

A chip packaging casing for packing chips and also serving as a chip supply source comprises a substantially plate-like body having a spiral passageway formed in its interior, and a plurality of chips received in a row in the spiral passageway of the body. The plate-like body further has a chip-outlet formed therein as a continuation of the spiral passageway to communicate with the exterior of the body and at least one air-intake formed therein to communicate between the passageway and the exterior of the body. The air-intake is adapted to be connected to an air supply source and serves to facilitate the forwarding of the chips along the passageway toward the outlet to discharge the chips form the outlet. A chip supply mechanism is provided for supplying chips to a mounting head of an automatic chip mounting apparatus by using the chip packaging casing.

A television camera capable of correcting shadings caused by digital registration faculty employed in a multi-tube type color television camera. The television camera comprises differentiating circuits for generating differentiated waves of correction waveforms used for adjusting registration, and non-linear circuits for processing the differentiated waves. Outputs of the non-linear circuits control the gain of a video signal circuit so that components responsible for the generation of shadings can be removed from a video signal.

摘要:
In a solid state imaging device in which two signals on two horizontal scanning lines are read out simultaneously for easy image enhancement, the two signals read from the two horizontal scanning lines are subtracted from each other while they are added together, and the difference signal is added to the sum signal so as to produce a video signal subject to the image enhancement. As a solid state image sensor, a MOS type image sensor as well as a CCD, CID or CC type image sensor may be used.

A secondary battery has a progressively degrading SOC that is an SOC at which the battery performance degrades during storage, and is charged and discharged by a controller. An information processor holds a first threshold value set in advance and lower than the progressively degrading SOC of the secondary battery, and a second threshold value set in advance and higher than the progressively degrading SOC, makes the controller continue an operation to charge the secondary battery from the first threshold value to the second threshold value at the time of charging the secondary battery based on the value of the SOC of the secondary battery detected by the controller, and makes the controller continue an operation to discharge the secondary battery from the second threshold value to the first threshold value at the time of discharging the secondary battery based on the value of the SOC of the secondary battery detected by the controller.

An electric device has an electric power measurement unit with an electric power detection element measuring consumed electric power and an information communication element transmitting the measured power. An electric power meter has an information communication element measuring and transmitting total electric power consumed indoors. An information processing unit stores the measured values in every predetermined sampling period. If a difference α of two measurement values of the electric power detection element is a finite value, the information processing unit calculates and stores both a difference β of two measurement values of the electric power meter corresponding to the two measurement values and β/α, and calibrates the amount of electric power consumed by the electric device and that is measured by the electric power detection element using a median of values of β/α obtained in a predetermined measurement period or a median of a predetermined number of values of β/α.
摘要:
A secondary battery has a progressively deteriorating SOC in which battery performance deteriorates when the secondary battery is stored, and is charged and discharged by a control device. An information processing device stores a preset first threshold smaller than the progressively deteriorating SOC of the secondary battery and a preset second threshold greater than the progressively deteriorating SOC, and separates the range from the minimum SOC to the maximum SOC of the secondary battery into, at least, two regions by setting the section from the first threshold to the second threshold as a boundary to thereby cause the control device to charge or discharge the secondary battery within any of the above regions.
