Inventor: BIRMILI GERD
IPC: G01S13/93
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To provide the method and device for controlling the vertical movement of an automobile by which advantageous interval adjustment suited to traffic is enabled even in the range of a slow speed to vehicle stoppage. SOLUTION: When a stipulatable operation start condition including the presence of a preceding vehicle is present, an interval adjustment mode for automatically adjusting the interval of a vehicle and the preceding vehicle is operatable. In this case, when the operation start condition for which the traveling speed of the vehicle is below a stipulatable speed limit value is present, the interval adjustment mode 1 is not directly operated, a preparation mode 3 is operated first and the interval adjustment mode 1 is operated by signals inputted on a user side from the preparation mode 3.  Further, when a stipulatable operation stoppage condition is present, without immediately shifting from the interval adjustment mode 1 to an inoperative mode 2, it is shifted to an idle traveling mode 4, the vehicle is continuously decelerated in the idle traveling mode 4 and operation stoppage request signals are displayed. By the input of user side interval adjustment stoppage signals, the interval adjustment is completely stopped.

Since the starting materials are in the form of powder, they are liable to remain in the passage. The remaining starting materials are chipped and pushed into the furnace 1 with the acute chipping part 12 having an inclined plate 12a for thowing starting materials toward the upper part of the inside of the furnace 1. During this time, the piston 3 stops the dropping of starting materials. Clogging in the feed of starting materials can be prevented by intermittently repeating said action.

Title: Ink jet recording system
Inventor: ARAI RYUICHI
IPC: B41M5/52
Filed: 1984-11-14
Abstract: PURPOSE:To obtain picture excellent in clearness and storability of dye colors by using a recording material containing less than a specific amount of active acids to be stayed in recorded pictures for ink jet recording. CONSTITUTION:When dyes containing water-soluble or hydrophilic groups, e.g., sulfonic acid, carboxyl, amino, hydroxyl, or salts of these, which are used in ink, are used for printing on recording materials, if the recording face of the recording material contains too much acids, the water-soluble or hydrophilic groups of the dye are affected. In short, the electron density of the chromophores of dye is changed, and the color-forming property of the dye is damaged to cause discoloration or fading. In forming ink-receiving layers on plastics as base materials for this reason, neutral or basic water-soluble or hydrophilic resins containing no sulfonic acid or carboxylic acid group and used, and these are neutralized as needed to lower their acidity.

Title: Terminal equipment
Inventor: TAKANO SEIJI
IPC: H04L25/02
Filed: 1985-10-24
Abstract: PURPOSE:To shorten the rise time of a transmission line voltage by providing a transmission line with an output part periodically supplying one level in synchronization with a clock, a zero level detection part and a control part and stopping the output at one level of the output part after a preset time lapses if the output of the detection part is at one level. CONSTITUTION:Right before the level of the transmission line 2 rises, at least one transistor 32 of a transmission circuit 3 is turned on, and an equivalent load capacity 5 is discharged. When he level of a transmission signal 301 changes to turn on all of the transistors 32 in the transmission circuit 3, the output part 11 starts supplying one level to the transmission line 2. The output part 11 keeps charging the equivalent load capacity 5 at a low output impedance and prompts the rise of the voltage waveform of the transmission line 2. After a fixed time, the output level of the control part 13 changes from '1' to '0', and the output of the output part 11 stops. Accordingly, a signal transmission speed can be improved without dropping the drive ability of the transmission circuit.
