Title: Scrambling system
Inventor: SATO NOBUO
IPC: H04L9/22
Filed: 1988-04-15
Abstract: PURPOSE:To hold the privacy of communication data by preparing plural kinds of pseudo noise codes, and using the plural kinds of pseudo noise codes by switching when a specific pattern decided in advance is generated in serial data. CONSTITUTION:A data pattern detector 2, when performing the collation of the specific pattern with the pattern in input serial data and detecting the specific pattern in the input serial data, outputs a detection signal to a pseudo noise code signal generator(PNG)3. The pseudo noise code signal generator 3 is provided with plural kinds of pseudo noise code signals possible to generate, and outputs a pseudo noise code signal generated at every issuing of the detection signal from the data pattern detector 2 to a scrambling circuit 1 by switching sequentially. Thus, since the pseudo noise code used in scrambling is changed appropriately, it is possible to hold the privacy of communication even when a third party recognizes the circuit constitution of the pseudo noise code generator.

Title: Ink jet head and production thereof
Inventor: MIZUTANI HAJIME
IPC: B41J2/16
Filed: 1993-04-19
Abstract: PURPOSE:To increase the resistance value across electrodes by expanding the distance between the electrodes, to reduce the deterioration of an insulating layer to enhance the durability of a head and to ensure the correspondence of a wide ink layer by arranging ink supply part passages composed of an insulating material to an ink supply part.

Title: Oscillation integrated circuit and oscillation circuit
Inventor: HASEGAWA EIICHI
IPC: H03B5/32
Filed: 1994-04-28
Abstract: PURPOSE:To suppress the useless consumption of power in an oscillation stop mode, to easily set the duty, and also to easily charge the design according to the desired oscillation frequency such as the basic wave (primary), third and fifth overtones, etc. CONSTITUTION:The oscillation starts when the bias voltage obtained by the division of voltage carried out by the resistances RD and RU is applied to an input terminal IN1 of a CMOS inverter 1 connected to a crystal vibrator 3. As the inverse potential of the inverter 1 is decided by the bias voltage not by the resistance value of a feedback resistance 5 that is decided by the oscillation frequency, the duty can be easily set and the design is also easily changed according to the oscillation frequency. Meanwhile the oscillation is stopped when a control terminal ST is set at 'H', a MOS transistor 7N is turned on, and the terminal IN1 is connected to a power terminal VSS. The terminal IN1 is cut from an output terminal OUT1 by a capacitor 4 so that no current flows to a power supply VSS from the terminal OUT1. Thus the resistance value of the RU is satisfactorily increased and the current flowing between both power supplies VDD and VSS can be suppressed.

Inventor: SATO MICHIKO
IPC: G01S5/06
Filed: 1994-04-28
Abstract: PURPOSE:To provide a method for highly accurately detecting position of a moving station in a hyperbolic method. CONSTITUTION:Three (e.g. 53, 54 and 55) of fixed stations 52-58 are selected to receive transmission waves from a moving station 51 having few delay errors. Coordinates of initial position of the moving station 51 are obtained based on the definition of a hyperbolic method from receiving waves of the fixed stations 53-55. A moving speed and a moving direction of the moving station 51 are detected by receiving waves from the moving station 51 at the plurality of fixed stations 52-58. An estimated position 60 of the moving station 51 a predetermined time later is obtained from the data and coordinates of the initial position. Three fixed stations (e.g. 54, 56 and 58) are selected from a plurality of fixed stations 52-58 so that the positional coordinates of the moving station 51 can be obtained most properly at the estimated position 60 by the hyperbolic method. Waves of the moving station 51 moved to the estimated position 60 are received by the three fixed stations 54, 56 and 58, whereby coordinates of a true position of the moving station 51 are obtained based on the definition of the hyperbolic method.

Filed: 1984-05-07
Abstract: PURPOSE:To jet small ink drops necessary for printing each time an electrical pulse is applied for printing by setting the maximum value of a liquid pressure within a specified range when jetting is performed in a pressure chamber of a print head. CONSTITUTION:The jetting system holds a static state at the point 63 until immediately before a positive input voltage pulse 62 is applied to a pressure plate at the time t1. At the time t1, as the positive voltage is applied to deflect the pressure plate, pressure working on ink increases up to about ten times and hence, the maximum value (point 64) of the pressure working on the ink is set in the range of 1-20psi. A high pressure at the point 64 acts as driving force of the ink in the orifice.

Title: Semiconductor laser device
Inventor: KOIZUMI YOSHIHIRO
IPC: H01S5/00
Filed: 1988-04-14
Abstract: PURPOSE:To improve such characteristics as a threshold current and an external differential quantum efficiency by a method wherein a buried layer which buries a mesa type active region is formed of a high-resistance semiconductor layer. CONSTITUTION:As the whole surface, which is located on both ends of a mesa, of an n-type substrate 17 is covered with a high-resistance semiconductor layer (Fe-doped InP layer) 13, a sufficient resistivity is obtained. Moreover, a p-type impurity forming region 10 is provided in the vicinity of a part, which comes into contact to an electrode 11, of an N-type low-resistance region on the sidewall of the mesa. As this region 10 exists, a p-n junction is formed between the region 10 and the low-resistance region on a path from the electrode 11 to lead to the substrate 17 via the N-type low-resistance region. Accordingly, in order to make a leakage current flow through the path from the electrode 11 to lead to the substrate 17 via the low-resistance region, a voltage higher than the diffusion potential of the p-n junction must be applied. As the diffusion potential in an active layer 16 is lower than that in the InP layer 13, a current first flows to the side of the layer 16 if a voltage is applied to a semiconductor laser. When the laser is oscillated, the current keeps flowing.

Title: Thermal superconductive switch
Inventor: MITSUNE SUSUMU
IPC: H01L39/20
Filed: 1983-05-27
Abstract: PURPOSE:To obtain a thermal superconductive switch which has working steps entirely different from a thermal superconductive switch by forming an electrically insulating layer Nb3Sn layer on a substrate used also as a heater, winding it in a pancake shape and molding it with epoxy. CONSTITUTION:In a thermal superconductive switch necessary to perform a superconductive permanent current mode used for a magnetically levitating train or the like, a substrate 1 is formed of stainless steel and used also as a superconductive switch OFF heater. Accordingly, it has low electric conductivity and is selected to have durability against heat such as metallizing or heat treatment of Nb3Sn. An electric insulator 2 such as ceramics is coated on the substrate 1. The Nb3Sn layer 3 is metallized thereon. This tape is the heat treated in a heating furnace to form the layer 3 tape having high critical current and high critical temperature. This tapelike superconductive conductor is wound in a pancake shape through an electrically insulating tape 4, covered with resin such as epoxy as a thermally insulating layer 5. Or, the electrically insulating tape is omitted, and an electric insulator to be coated on the substrate 1 instead may be coated on both sides of the tape. In this manner, the manufacturing workability can be remarkably improved, and arbitrary normal conductive resistance value and thermal capacity thermal superconductive switch can be obtained.
