Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To provide the KARAOKE device which reproduces an optimum ICM (information advertisement) in accordance with the configuration of a store and the customers. SOLUTION: A communication distribution center classifies plural ICM data (information.advertisement data) into common data, data for KARAOKE boxes, data for night clubs and data for home use and stores these data. When a terminal device such as a communication KARAOKE device makes a request for a down loading to the center, the store configuration, in which the terminal is installed, is transmitted and only the ICM data suitable to the configuration are down loaded. When the ICM is reproduced at the terminal, an optimum ICM is retrieved based on the customers at that time and reproduced. Moreover, the ICM data down loaded from the center are reprocessed (edited) at the terminal side and reproduced. Thus, an optimum ICM is always reproduced.

Title: Ink droplet speed difference detection apparatus of charge deflection type multihead in jet printer
Inventor: KOIKE TAKANAO
IPC: B41J2/125
Filed: 1985-04-08
Abstract: PURPOSE:To make it possible to simply detect the shift of the speed difference between ink droplets, by detecting the shift of a charged droplet arrival time up to the detection electrode between heads by added output obtained by adding the detection outputs of the charged droplets of the heads. CONSTITUTION:When charge voltage is alternately applied to charge electrodes, for example, of Y and M of a recording head 4 and times Y, M reaching a detection electrode after charging coincide provisionally, the output voltage of the detection electrode comes to output almost only comprising a DC component because both outputs are alternately compensated to each other as shown by detection output 1. Detection output is cut in an implifier 23 by a condenser C and not transmitted to the side CPU. When the time reaching the detection electrode after charging becomes long as compared with M if the ink pressure of M is lowered, detection output is outputted as shown by detection output 2 and an AC component passes through the condenser C to be transmitted to CPU. By this method, the speed difference of ink droplets between two heads can be detected.
