Title: Quasi-momentary companding differential pcm decoder
Inventor: OTA MASAYUKI
IPC: H03M7/50
Filed: 1989-04-21
Abstract: PURPOSE:To obtain a quasi-momentary companding differential PCM decoder with a small circuit scale by adopting a constitution such that the data of plural channels is decoded in time division by one circuit. CONSTITUTION:A data expansion section, a data interpolation section and a differential PCM decode section (including leakage arithmetic operation) are shared by plural channels and the output latch of each function block is concentrated to a RAM and sequence control is applied to signal flow. A RAM 22 stores tentatively the output data of each function block by all channels. The data interpolation section and the differential PCM decode section apply data interpolation and differential PCM decoding to the data of plural channels in time division.

Title: Method and system for transmitting data in line concentrated network
Inventor: HAMADA TAKUSHI
IPC: H04L12/56
Filed: 1992-04-22
Abstract: PURPOSE:To suppress data transmission delay time by repeating a data frame to be received to the transmitter of the destination by receiving a destination address contained in the data frame. CONSTITUTION:The data frame from a transmitter 3 having a transmission request is received by a line concentrator 1, the line concentrator 1 judges the transmitter 3 to repeat this data frame by receiving the destination address in this received data frame, and the data frame is repeated to a transmission line 2 to connect this transmitter 3. For example, a star-shaped network to exchange information one and another is constituted by respectively connecting various terminals 41-4n such as computers, work stations or personal computers distributed in various areas through transmission lines 21-2n to the line concentrator 1. In this case, the exchange operation is realized by high-speed switching preserving media access control. Thus, not only the large capacity of packet information can be transmitted but also the transmission can be easily realized at real time.

Title: Gas discharge display unit
Inventor: OTSUKA AKIRA
IPC: H01J11/10
Filed: 1985-05-16
Abstract: PURPOSE:To surely and easily cause priming discharge and enlarge the operational margin for the fluctuation in the potential of a display electrode capacitively coupled along with the priming discharge, by providing a construction to cause the priming discharge on an electrode portion having a thin insulator layer. CONSTITUTION:Electrodes 18a, 18b for priming discharge are provided at end portions and do not directly face a display electrode 2 but driving electrodes 4, 5. As a result, the priming discharge can be directly caused between the electrode 18a and the driving electrode 4 and between the electrode 18b and the driving electrode 5 through thin protective insulator layers 6, 16. For that reason, the priming discharge is greatly facilitated. Since the potential of the display electrode 2 in a capacitively-coupled state fluctuates due to discharge in multiple driving based on capacitive coupling, the priming discharge is caused by the driving electrodes 4, 5 to reduce the fluctuation so as to enlarge the operational margin for the fluctuation.

IPC: B60T13/66
Filed: 1985-05-17
Abstract: PURPOSE:To simplify the control of a parking brake, in a railway vehicle provided with a convenient driver's cab, by automatically releasing a parking brake in accordance with an output instruction signal relating to the advancing direction of a reverser during running of the vehicle controlled from the driver's cab. CONSTITUTION:In a front head vehicle 1, when a reverser 3 is manipulated in the advancing direction, an advancing direction instruction line 3F falls in a signal existing condition. At this time a reverser 3 in a vehicle 2 is selected in the reverse direction, and therefore, an EOR circuit 4 falls in its output condition unless a rearward advancing direction instruction line 3R is fed with a signal. Therefore, the coil 5a of a parking brake solenoid valve 5 is energized to change over the valve 5 to its connecting position. As a result compressed air in an air source 6 is fed into an air chamber 7 in a parking brake cylinder 7 to press a piston 7a overcoming a spring 7b to release the brake. With this arrangement either one of the reversers 3 in the vehicle 1, 2 is operated, the instruction signals are fed to the directional instruction lines 3F, 3R to automatically release the parking brake.

Title: Image forming device
Inventor: FUNATANI KAZUHIRO
IPC: G03G15/01
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To prevent the soaring up of toner during a nondeveloping operation and further, the occurrence of staining on the backside of a paper sheet by controlling the value of a bias voltage applied to developing units, during the nondeveloping operation, in accordance with magnetic or nonmagnetic toner. SOLUTION: The image forming device is provided with the developing unit 4d using the magnetic toner and the developing units 4a-4c using the nonmagnetic toner and the bias voltages are applied to the developing units 4a-4d, so that the toner soars up toward a photoreceptor 101. For preventing the soaring up of reverse toner, a DC bias of a DC bias voltage is applied onto a developing sleeve, during the nondeveloping operation as well, to make the potential difference between the surface of the photoreceptor 101 and the developing sleeve small. In such a case, an optimum DC bias value is different because of the difference between the developing characteristics of the magnetic and nonmagnetic toners so that the developing biases are set at different values in the magnetic and nonmagnetic toners.  Thus, the soaring up of the toner during the nondeveloping operation, in all colors can be prevented and a multicolor image without staining on the backside of the paper sheet can be obtained.
