  • Patent number: 5441618
    Abstract: Arranged in a series are an electrolyte tank capable of holding one of a number of substrates, each substrate having a conducting film thereon, and a cathode so that the cathode and substrate face each other in an electrolyte, an anodizing chamber for anodizing the substrate, a pretreatment chamber for calcining a photoresist mask put on part of the conducting film, and a post-treatment chamber for washing and drying the anodized substrate. A substrate transportation mechanism is provided for serially transporting the substrates one by one from the pretreatment chamber to the post-treatment chamber via the anodizing chamber. In the anodizing chamber described above, a formation voltage is increased to a value such that an oxide film with a desired thickness is formed so that the value of a current flowing through an aluminum alloy film as the conducting film is kept constant with the current density ranging from 3.0 mA/cm.sup.2 to 15.0 mA/cm.sup.2.

  • Patent number: 5442125
    Abstract: A signal processing apparatus according to the present invention is used as a sound source, an effecting machine and/or a communication equipment, which simultaneously generates or processes a plurality of musical tones and sounds on the basis of a plurality of input data such as performance data, musical tone data and/or communication data. This signal processing apparatus stores a program prepared for controlling operation to generate or process musical tones and sounds only for one channel. The program is read out in accordance with a lower bit of a readout counter. A upper bit of the readout counter is used to designate a channel to which the generated or processed musical tones and sounds are assigned in accordance with the read out program. As a result, only a small area is required for storing the program and a simple construction may be employed in the apparatus.

  • Patent number: 5442602
    Abstract: Shock absorbing members are attached to an outer rim of a back surface of a wristwatch case body at 6- and 12-o'clock portions thereof, and they extend outward and curve downward. Each of the shock absorbing members has rising portions extending from its both side ends and which are freely swingably attached to the wristwatch case body to a circumferential surface of the wristwatch case body. In addition, a part of a front surface and the circumferential surface of the wristwatch case body are covered by a first cover member made of soft synthetic resin, and the first cover is partly covered by a metal-made second cover member. When shock is applied to the front and circumferential surfaces of the wristwatch case body, the shock is reduced or absorbed by the rising portions of the shock absorbing members. When shock is applied to the back surface of the case body, the shock is reduced or absorbed by the shock absorbing member.

  • Patent number: 5440413
    Abstract: A polarizer and an analyzer are respectively arranged on the incident and exit sides of a twisted nematic liquid crystal cell, and at least one biaxial retardation plate is arranged between the polarizer and the analyzer. The biaxial retardation plate is arranged such that its phase delay axis is parallel or perpendicular to the aligning treatment direction of an aligning film on the incident side of the liquid crystal cell. The polarizer is arranged such that its light-transmitting axis is parallel or perpendicular to the incident-side aligning treatment direction. The light-transmitting axis of the analyzer is set to be perpendicular to the light-transmitting axis of the polarizer. A liquid crystal material sealed in the twisted nematic liquid crystal cell is twisted at about 90.degree.. The biaxial retardation plate has a refractive index n.sub.X in an extending direction of the retardation plate, a refractive index n.sub.Y in a direction perpendicular to the extending direction, and a refractive index n.

  • Patent number: 5438657
    Abstract: Document data stored in a document storage area are extracted line by line to analyze the structure of the document data. The document layout information is extracted from the analysis result. The extracted layout information is stored, as learning data, in a document layout information learning area. In format conversion, the document data to be output, which is extracted in the same manner as described above, is converted on the basis of the learning data. Document data having a consistent layout is output to a CRT or a printer in accordance with the converted layout information.

  • Patent number: 5438679
    Abstract: Data input from a key switch is displayed on a liquid crystal display, and whether to store the data in a RAM or an EEPROM is selected by a selection switch. If the EEPROM is selected, a CPU turns on a power switch to apply a high voltage to the EEPROM to write the input data therein. Data stored in the RAM and the EEPROM are read out upon operation of a search switch and are sequentially displayed on the liquid crystal display. It is clearly indicated on the display whether the currently displayed data is read out from the RAM or the EEPROM. With this operation, if data which is required to be protected against disconnection of a power supply voltage or a drop in power supply voltage is stored in the RAM, the data can be stored in the EEPROM.

  • Patent number: 5424230
    Abstract: An amorphous silicon hydride thin film is deposited on an insulating body by a plasma CVD method, and is then heated for dehydrogenating the amorphous silicon thin film so that a dehydrogenated amorphous silicon thin film containing hydrogen of 3 atomic % or less is formed. The insulating body may be an insulating substrate (such as a glass substrate) alone, or a combination of an insulating substrate with an intermediate insulating base layer thereon. Impurity ions are injected into the dehydrogenated amorphous silicon hydride thin film to form source and drain regions. Excimer laser beams are applied to the dehydrogenated amorphous silicon thin film, thereby polycrystallizing the amorphous silicon thin film into a polysilicon thin film and activating the injected impurity ions.

  • Patent number: 5425138
    Abstract: An apparatus of this invention is designed to output document data including ruled line data upon proportionally arranging the data on one page to prevent the disruption of the relationship between the column and row positions of the ruled line data on the page. A document arranging section sequentially changes the character sizes stored in text and table format memories to develop document data of a designated page in a layout development memory. If the developed document data occupies 3/4 or more of a printable region, the data is printed according to the current format by a printing section. If the character size exceeds a limit value set in a format table before the area of the data becomes 3/4 or more of the printable region, the line spacing and the upper margin are sequentially changed in the same manner. If a ruled line causes overflow when the character size of ruled line data is changed, the character size is decreased by one step to prevent line feed of the ruled line.
