Title: Optical disk device
Inventor: ASANO TAKUYA
IPC: G11B20/10
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To precisely binarize an address signal even when upper/lower balance of the address signal is different greately by precisely detecting a threshold value slicing the upper side signal and the lower side signal of the address signal, imparting an offset to the address signal according to its difference and automatically adjusting the balance between the upper side and lower side. SOLUTION: Comparators 3, 4 binarize the address signals based on the threshold values (+), (-) of symmetric voltages to output them as upper side and lower side addresses. An OR gate 6 adds these outputs to make them binarized addresses, and monostable-multivibrators 5, 7 output upper side and lower side address detection signals. When the upper side and lower side of the address signal are unbalanced, the threshold values (+) are detected on specified two sections in a header field, and the balance of the signal before binarization is changed suitably according to the difference. Thus, by offsetting both differential address signals, and taking the difference signal of both signals, the upper/lower balance is improved, and the upper side and lower side signals are sliced precisely.

Moreover, breakage of strand is not caused due to absence of bubbles in the concentrate. Thus, a concentrate which can form strands satisfactorily is obtd.

Title: Ejector of ink jet printer equipped with single terminal heating element allowing selectable liquid drop size
Inventor: JIYON AARU ANDORIYUUSU
IPC: B41J2/05
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To jet an accurately selectable size liquid drop. SOLUTION: A thermal ink jet recording head contains an ejctor wherein a heating surface is arranged in a passage in which liquid ink is held. On the heating surface a first part 30 for radiating heat in first output density, and a second part 32 for radiating heat in second output density are specified. At a constant comparatively low voltage or pulse width, occurrence of nucleus of an ink bubble comes to be generated only in liquid ink adjacent to the first part 30 of the heating surface. At a comparatively high voltage or pulse width, occurrence of the bubble nucleus comes to be generated over the first and second parts. A size of the bubble in which the nucleus is generated influences directly the size of the liquid drop to be expelled. A discontinuous boundary between two parts of the heating surface allows a selectable spot size to be formed with the ejector.

Title: Method and device for liquid detection
Inventor: NOSE TAIJI
IPC: G01V8/12
Filed: 1984-03-01
Abstract: PURPOSE:To easily detect whether liquid is present or not by making light incident on the boundary surface on a liquid side below a critical angle, and detecting reflected light from the boundary surface by a photodetecting element. CONSTITUTION:A boundary surface 5 is formed of a solid body 3 and an air layer on the transparent solid body 3 at the side of a light emitting element 1 and the photodetecting element 2, and a boundary surface 6 is formed of the transparent solid body 3 and air on the transparent solid body 3 at the side of liquid. Part of light which is emitted by the light emitting element 1 and arrives at the boundary surface 5 is refracted and transmitted in the transparent solid body 3 to reach the other boundary surface 6, by which part of it is reflected to reach the photodetecting element 2 through the boundary surface. When the liquid which varies in amount contacts the transparent solid body 3, the quantity of reflected light on the boundary surface 6 varies and the quantity of light reaching the photodetecting element 2 varies. Consequently, it is judged easily whether the liquid is present or not from the output of the photodetecting element 2.

Appropriate contact pressure is thus caused between a running face of a rail 1 and the wheels 5, 8 which run on the face. When the crane is started, no slip occurs. Even if the rail 1 is obliquely laid, the saddles automatically swing to keep appropriate contact pressure between the running face and the wheels 5, 8.
