Abstract: An oscillation device includes a buffer device, a feedback device for feeding back an output of the buffer device to an input thereof and a charging device and a discharging device connected to the input of the buffer device. The charging device includes a first switching device that is turned on and off based on the output of the buffer device and a first current control device that controls the current flowing into the input of the buffer device through the first switching device. The discharging device includes a second switching device that is turned on or off based on the output of the buffer device and a second current control device that controls the current flowing out of the input of the buffer device through the second switching device.

Abstract: There are provided a drive unit which can be adjusted to various mounting forms and which can be reduced in power consumption and scale, and an electronic equipment containing such a drive unit. When a control signal DIR is switched from L-level to H-level, a logical operation circuit comprising a plurality of logic gates changes a READ address A which is in turn outputted toward a display memory. More particularly, an inverted signal of the READ address A is outputted as a READ address B. Thus, an image displayed on a liquid crystal display panel is vertically inverted. The drive unit can be adjusted to various mounting forms for the liquid crystal display device. Where the display memory includes a code data memory and a CG-ROM, first and second logical operation circuits are provided for each of the code data memory and CG-ROM. The output of the CG-ROM is connected to a third logical operation circuit which performs the lateral inversion for each character.

Abstract: The present invention provides a matrix type display device which simplifies the process in a display signal generating circuit while relieving the load on an external CPU, and which arranges freely character and icon display areas while preventing the quality of display from being degraded by the shadow phenomenon and others. A display code memory stores character display codes and icon display codes for one image at a desired address arrangement. A pattern generating circuit transfers image patterns for the display codes to a display signal transferring circuit through a multiplexer. A decoder selecting device is responsive to a decoder select signal to select a decoder, thereby controlling voluntarily the timing of latch signal generation. Display signal input in the time division manner is latched in first and second latch circuits through the latch signal. Thereafter, the display signal is transferred to a signal electrode driving circuit through a line memory to display an image on a matrix panel.

Abstract: An oscillation device and a display data processing device adjust variables such as the duty ratio of the oscillation frequency, and control autonomously timings between components such as memories. First and second switching devices disposed within charging and discharging devices are turned on and off by an output of a MOS buffer, enabling adjustment of the frequency and duty ratio of an oscillation signal. Equivalent circuits are provided corresponding to display data RAM, CGROM, and address decoders, data is read sequentially from the display data RAM and the CGROM when an EIRAM signal is enabled, and a DLAT signal is stored in a driver circuit. The equivalent circuits enable each of EIROM, EILAT, and RS signals at points when the read data is confirmed or thereafter. When the RS signal is enabled, EIRAM and other signals are sequentially disabled and the display data RAM and other components switch to a precharge operation.

Abstract: An objective of the present invention is to provide a power supply device, a liquid crystal display device, and a method of supplying power that can enable designs with lower power consumptions and can also enable higher display qualities. A first voltage Vx, which is a constant voltage, is generated by a first voltage generation portion in a voltage regulation portion. A second voltage Vy having a value independent of that of Vx is generated by a second voltage generation portion, and Vx and Vy are added by an adder portion to generate a regulated voltage Vreg. A control portion provides variable control of Vy within a voltage regulation range that is defined to include Vx. The regulated voltage Vreg is divided by a voltage divider portion within a multi-value voltage generation portion. The impedances of voltages V2 and V4 are converted by first impedance conversion portions (n-type OP-amps), and the impedances of voltages V1 and V3 are converted by second impedance conversion portions (p-type OP-amps).

Abstract: A substrate electrode having a plurality of substrate holders capable of causing a substrate to tilt by an arbitrary angle .theta. relative to the horizontal plane is provided. A plurality of auxiliary electrodes are arranged substantially vertically below the substrate electrode and between the substrate electrode and a target. The substrate electrode and the auxiliary electrodes are electrically insulated from the target. Bias voltage applied to the substrate electrode and the auxiliary electrodes causes the plasma boundary between the cathode dark space and the negative glow to form a cathodic plasma space having a parabolic section, thus forming a crystal-oriented thin film on the substrate surface.

Abstract: A fire-resistant, light weight construction material is prepared by subjecting fly ash and/or paper sludge incineration ash to a swelling treatment with a mineral acid to prepare a slurry; and kneading, shaping and hardening the slurry.

Abstract: There is disclosed a refrigerated display cabinet having a refrigerating chamber and a mechanical chamber, and an access opening into the refrigerating chamber that is adapted to be opened and closed by a transparent cover panel sliding longitudinally of the access opening. The cover panel is mounted on guide rail mechanisms each of which comprise a frame with wheels and rail elements. Each frame is provided with two sealing flanges which extend vertically and horizontally from one edge of the frame into sealing engagement with the rail element when the transparent cover panel is closed thereby closing or sealing the gap between the frame and the rail elements to prevent leakage of cooled air from the refrigerating chamber.

Abstract: There is disclosed a refrigerated display cabinet provided with a refrigerating chamber and a mechanical chamber in which the rear wall of the refrigerating chamber and a rear plate that closes the open end of the mechanical chamber are in a common plane spaced from the plane defined by the rear edges of the side walls of the cabinet to provide a space between the cabinet and a wall against which the cabinet is set so that air can be exhausted from the mechanical chamber through said space and directed through a duct onto the transparent panels through which goods in the cabinet are displayed to prevent condensation on said transparent panels.
