Title: Data reproduction device
Inventor: URANO TAKAYOSHI
IPC: G10K15/04
Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To make changeable the individual reproduction speed of music data by separating music data and video data received under the synchronized condition, recording the music data temporalily, and then performing change control in the data at the rate of read-out speed of music reproducer means. SOLUTION: A pitch change command is received through a remote controlled light reception unit 5, and a control unit 10 sends out a command to change the speed of reading music data or displayed word data out of a storing unit 13 to a video reproduction and synthesizing unit 15. Based thereon, the units 14, 15 change the speed of reading the music data or displayed work data out of the unit 13. Accordingly without changing the reproduction speed of video data the regeneration speed of music data and displayed work data relating to 'karaoke' (prerecorded backing music) play can be changed to the speed a user want to have.

Title: Method for removing impurity in plating liquid and device therefor
Inventor: HIDA YUKIO
IPC: C25D21/18
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a method for purifying a plating liquid from a plating device which eliminates the cost accompanying the transfer of the plating liquid and the danger in work and a device therefor. SOLUTION: This method removes the impurities in the plating liquid by using an active carbon housing container which obviates the splashing of active carbon into the plating liquid and allows the permeation of the plating liquid. In such a case, for example, the active carbon housing container which obviates the splashing of the active carbon into the plating liquid and allows the permeation of the plating liquid is immersed into the plating liquid and the plating liquid is stirred or the plating liquid discharging from a plating cell 1 is introduced to a filter vessel 3 contg. the active carbon where the impurities in the plating liquid are removed. The plating liquid is then recirculated into the plating cell 1. For example, the work for removing the impurities in a semiconductor line is made possible and the contaminated plating liquid is recovered.  The labor for transferring the plating liquid to the plant of a plating liquid producer and the cost required for the same are reduced. Since the filtration of the plating liquid at all times is made possible, the deterioration of the plating liquid by org. matter is suppressed and the liquid life of the plating liquid is prolonged.

Title: Thermal recorder
Inventor: TAKAHASHI MASATOMO
IPC: B41J2/36
Filed: 1983-11-15
Abstract: PURPOSE:To equalize the density of recording even when strain occurs in a recording head by controlling recording energy of pulse to be applied to heating elements according to heats proportional to the amounts of strain to be generated during the driving of the recording head. CONSTITUTION:Strain characteristics for heat of a recording head 1 are measured in advance. On the basis of the strain, recording pulse widths W1-W3 for the temperatures of the recording head 1 are stored in a temperature strain vis pulse width table 7 for the blocks A-F of a recording driver 5. When recording data are received by a recording controller 6, the temperatures of the head 1, detected by a thermister 4, are input through a detector 8. On the basis of the temperatures, corresponding recording pulse widths W1-W3 are read out of the table 7 for each block. The driver 5 for each is driven, current of pulse width corresponding to each heating element of the head 1 is applied, and recording is made on the recording paper 2. Recordings of uniform density can thus be obtained even when temperature strain occurs in the recording head.
