Abstract: A gaming apparatus which comprises a slot machine capable of accepting either paper currency, preprinted coupons, or cash out slips. The slot machine also includes a printer that prints and dispenses cash out slips which include a bar code representing a unique identification that provides the amount of "winnings". The cash out slips can be scanned into a separate currency dispenser at a Cashier's Station for receiving currency, either from the dispenser or from an attendant. A central processing unit (CPU) generates the unique codes for regulating the game to be played, the wager limits of the game and the validity of the free play coupons or the cash out tickets. The above gaming system avoids having to use coins or tokens in the operation of slot machines.

Abstract: A synchronous dynamic random access memory has spare columns which can be tested before shipping. In the memory, a mode set register outputs a multibank write signal in the test mode. A CBS latch circuit generates not only a signal for selecting the spare column decoders in banks and in the test mode but also signals for selecting the column decoders. Write driving circuits write the data onto the column lines selected by the column decoders and onto the spare column lines selected by the spare column decoders.
Abstract: Frequencies (f1 to f7) are selected in respective time slots (T1 to T7) according to digital data to be transmitted. Digital data to be transmitted is indicated by a combination of frequencies selected in the respective time slots. Since a single time slot can select a plurality of frequencies, e.g., f2, f4 and f5, the total number of frequency patterns which can be achieved is increased. Therefore, since the number of combined patterns of substantially available frequencies is also increased, the number of bits of digital data which can be transmitted in a single data cycle (a period related to T1 to T7) is increased, and a transmission efficiency is improved.
Abstract: A small and durable antenna for use with radio and microwave communications is formed as a helical conductor contained in a multilayered non-ferrite ceramic chip. The dielectric constant of the ceramic is selected to match the antenna to its operating frequency, which may be in the range of 0.5 to 10.0 Gigahertz. A process for making such antennas is also disclosed. The antenna may be used in portable terminals and other devices requiring small, durable and inexpensive antennae.

Abstract: An image recording machine (8) having a remaining toner detection unit arranged inside a main body of a developer (41). Toner (40) is housed in the developer main body. The image recording machine (8) also includes a scraper (57) which cleans toner (40) out of a recess (56a) of the remaining toner detection unit as it is rotated integrally with an agitator. A supply member (47) for supplying stored toner (40) to the recess (56a) of the remaining toner detection unit rotates with the scraper (57) and is arranged at a 90.degree. angle downstream from the scraper (57) relative to their direction of rotation. The supply member (47) is formed as a flexible member.
Abstract: In a sound volume setting device for a portable telephone which can exchange messages through a public base station and which can exchange messages through a home telephone as a base station, a service detector for detecting whether the portable telephone is under the service of a public base station or under the service of a base station of a home telephone is provided so as to always search the service state, and adjust the amplifications of an amplifier for a receiving speaker and an amplifier for a calling speaker automatically using an operating portion, to thereby set the volumes of a calling sound and a receiving speech sound at proper values in accordance with the service state.
Abstract: A semiconductor device includes a substrate, an insulation film formed above the substrate and containing silicon-fluorine bonds, and a titanium-based metal wiring layer formed on the insulation film, the titanium-based metal wiring layer containing fluorine which is diffused from the insulation film and has a fluorine concentration of less than 1.times.10.sup.20 atoms/cm.sup.3.
Abstract: A tape printing apparatus selects one of a plurality of kinds of print formats as a designated print format. Characters entered are arranged to form a character string. Print image data is formed by editing the character string based on the designated print format. Printing is carried out on a recording medium in the form of a tape being fed, based on the print image data.
Abstract: When different tape cartridges accommodating printing tapes having different hardness, thicknesses or widths are exchangeably mounted in the same printing apparatus, excellent printing can be obtained using the present embodiment. In a platen 12 provided in a tape cartridge 10, the harder, thicker or wider the tape T accommodated in the tape cartridge 10, the softer a platen rubber provided on a surface of the platen. The platen rubber 14 having a hardness corresponding to the properties of the tape T is used so as to obtain an ideal contact state between a printing head and the tape T regardless of the properties of the tape T when the tape cartridge 10 is mounted in a tape writer 1. Accordingly, the tape T can be properly conveyed by the platen 12 and a tape guide pin 26 regardless of its properties, and can be brought into contact with a printing head through an ink ribbon R in an ideal and consistent contact state.

Abstract: A toner image formed on the photosensitive body (21) is transferred to printing paper by applying a voltage from a transfer roller (25) in an image transfer section of an image forming device (1). The transfer roller (25) is provided with a transfer voltage generating circuit (31) connected to a control unit (30). Information about an optimum transfer voltage is gathered from a look-up table (34) provided in a memory (33), in accordance with environmental conditions such as temperature and humidity in the device (1) which are detected by a sensor (35). The voltage to be applied to the transfer roller (25) is determined by the control unit (30). The voltage applied to the transfer roller between sheets of printing paper is also changed in accordance with the detected environmental conditions.

Abstract: A high-frequency input/output terminal comprises a lower dielectric substrate in which are formed a bottom face ground layer, side ground layers, a line conductor and cofacial ground layers (formed on both sides of the line conductor on one and the same face of the lower dielectric substrate); and an upper dielectric substrate joined to the lower dielectric substrate so that portions of the line conductor and cofacial ground layers are sandwiched between the lower and upper dielectric substrate. In order to suppress return and insertion losses of signal in millimeter wave range due to a difference in transmission mode to improve transmission characteristics, the upper dielectric substrate is made thicker than the lower dielectric substrate. The width of the portion of the line conductor which is sandwiched between the lower dielectric substrate and the upper dielectric substrate is smaller than that of another portion. The cofacial ground layers are projected toward the line conductor.
