Title: Monitor for diffusible chemical
Inventor: VON BAHR PONTUS
IPC: A61B5/157
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To analyze a probe liquid after circulating it more than one time by making a pumping system that transports the probe liquid from a proximal permeation area. SOLUTION: A catheter probe 9 is structured by arranging concentrically an inside route 13 and an outside route 14. The outside route 14 comes into contact with the blood of a patient when used and is made of a liquid tight material, with the exception of an area 15 made up of a permeable material through which a chemical concerned passes, and the inside route 13 does not permeate a chemical. Both routes 13, 14 are separated in the housing 10, the inside route 13 extends to a peristaltic pump 17, penetrating the wall of the outside route 14 and returns to the outside route 14 that ends in the housing 10, forming a closed channel of a probe fluid. The pump 17 delivers the liquid to a specimen chamber 23 through a valve 20 following a channel 22 from the inside route 13.  When a new specimen is replaced with an old one, the valves 20, 21 are closed, and sensors 18a, 18b, 18c performs another analysis.

Title: Nozzle stuffing detector of ink-jet printer
Inventor: OOTA TOMOMI
IPC: B41J2/165
Filed: 1983-03-30
Abstract: PURPOSE:To detect the clogging without trying printing by a method wherein charged in drops are spouted out and the variation of an electric field intensity between an ink-jet head, which is the 1st electrode, and the 2nd electrode of a capping member is detected. CONSTITUTION:While a nozzle part 8 is covered by a nozzle covering cavity 9 of a capping member 6, a switch 16 is closed to apply a voltage between the 1st and the 2nd electrodes 12, 10. When the printing shaft direction S1 for nozzle clogging detection is transmitted from a printing controller 15 to an ink-jet head 3, a row of ink drops 17 from, for instance, an ink nozzle 8c are spouted out from a nozzle plate 12, which is the 1st electrode, against the 2nd electrode 10. When these charged ink drops 17 reach the 2nd electrode 10, an electric field intensity between two electrodes 12, 10 is varied and this variation is detected by an electric field detector 14. If the detection signal S2 from the detector 14 is put into the controller 15, the judgement that there is no clogging is made and if the signal S2 is not put into the controller 15, the judgement that there is clogging is made. Thus, the clogging can be accurately detected without trying printing.

Title: Magnetic recording and reproducing device
Inventor: SUZUKI YUTAKA
IPC: G11B15/02
Filed: 1989-03-06
Abstract: PURPOSE:To make the best use of an unrecorded part of a tape by automatically switching the tape speed when the remaining time of the tape running the at the 2nd tape speed converted into the 1st tape speed equals to the remaining recording time required. CONSTITUTION:The remainder of the total tape recording time is measured at the 2nd tape speed and is converted into the 1st tape speed. As recording proceeds, a set recording time is subtracted until it becomes zero. Then, a stop instruction is issued to a tape traveling means 18 to terminate recording. Before the remaining recording time becomes zero, the remainder of the tape is compared to the remainder of the set recording time. If the former is shorter than the latter, recording continues at the 2nd tape speed, and if the former is equal to or exceeds the latter, the tape speed is switched to the 1st tape speed to record at a standard speed. Thus, the tape speed is automatically switched to make the best use of an unrecorded part of the tape.

Title: Roll paper feeder
Inventor: ISHIDATE YOSHIYUKI
IPC: B65H23/08
Filed: 1983-03-30
Abstract: PURPOSE:To prevent a paper from changing of its nature due to feeding by providing a shaft to feed a roll paper successively by rotation with a brake device to control the revolution for feeding the paper steadily. CONSTITUTION:When a feed roll 3 is operated by an external signal, a shaft 5 is rotated with a board member 11 pressing a bearing 6, and a roll paper 1 is successively unrolled and fed passing between rolls 3 and 4. At this stage, a brake device, a brake roll 20 is brought in contact with a board member 23. But the frictional resistance between the roll 20 and the board member 23 is not so large that the revolution of the shaft 5 is not interfered. When a conveying means, the roll 3, is stopped, the shaft 5 is further rotated by inertia force to send out the paper 1. But, such inertia energy is absorbed by the frictional resistance between a surface layer 22 of the brake roll 20 and the board member 23 to stop the shaft 5 for sure. That is, the roll 3 and the shaft 5 are stopped almost at the same time.

Abstract: PURPOSE:To attain always a stable transfer efficiency independently of the density of toner images by controlling the quantity of light of a pretransfer lamp in accordance with the detected density of a target image. CONSTITUTION:A target 3 is scanned in the preceding stage of copying, and the electrostatic latent image of the target 3 is developed by a developing machine 9 and passes a PTL 10, a chute 11, a transfer corotron 12, and a density sensor 13 successively.
