Title: Liquid jet recorder and recording head for said recorder
Inventor: KASHIMURA MAKOTO
IPC: B41J2/175
Filed: 1989-06-02
Abstract: PURPOSE:To accomplish various types of detection with remarkably high response and enhanced reliability to improve the recording reliability of a recording head itself by a method wherein a fine wire to be electrically heated is provided in a recording liquid supply path, and the presence or absence of the flow of a recording liquid is detected based on the change of a voltage or current applied to the fine wire. CONSTITUTION:A fine wire 110, such as a platinum wire, is provided so as to block the center of a flow path of an ink flow detection sensor 100. When an ink in an ink supply path 6 flows with a constant current supplied to the fine wire 110, the fine wire 110 is cooled and, thereby, an electric resistance is changed. Then, a voltage fluctuation generated at this time is detected, where by a flow rate fluctuation up to several kHz is detected. Whether the detected voltage fluctuation corresponds to a flow in the case of a normal ink consump tion is compared, and whether the operation of a recording head 1 is normal is judged. The exhaustion of an ink in an ink tank 5 results in the stoppage of the ink flow in the ink supply path 6, the stoppage of cooling the fine wire 110, and a voltage increase with increasing electrical resistance. Thus, an ink exhaustion is detected.

CONSTITUTION:The latent heat type heat-accumulating material, e.g., sodium acetate trihydrate and the heat-transmitting medium, e.g., flon-113 are sealed in the contianer 1, leaving a space part A at an upper part of the container 1. When accumulation of heat is completed, the interior of the container 1 is filled with a molten liquid 2 of the heat-accumulating material and a saturated vapor of the heat-transmitting medium 3, 4. When release of heat is started by passing cold water as a cooling medium 200 into the radiator 6 in the above condition, the vapor 5 of the medium present in the space part A is condensed on a pipe wall of the radiator 6, and cold water 200 is heated by the latent heat of evaporation of the vapor 5. The condensate 4 of the medium dropping is collected by the liquid receiver 100, and slidingly flows through a conduit 120. Accordingly, the convection of the condensate 4 in a heat-accumulating material packing part 13 is smoothly effected, and the latent heat of melting of the molten liquid 2 can be effectively transferred to the radiator 6.

Title: Slider for measuring variation in floating quantity
Inventor: HIRANO YOSHIYUKI
IPC: G01B7/00
Filed: 1986-06-18
Abstract: PURPOSE:To measure variation in floating quantity without causing electric discharge on a metal medium disk surface by forming a spacer film on a slider surface to constant thickness. CONSTITUTION:An electrode 2 made of stainless steel is embedded in the slider 1 made of, for example, an NiZn ferrite material and floats over the disk with aerodynamic force. The disk is formed by plating an aluminum-made substrate 3 with Ni 4 and forming a magnetic film 5 of Co-Ni thereupon. The substrate 3 is grounded through a spindle shaft. A voltage of, for example, 1MHz and 5V is applied as a carrier signal to the electrode 2. Further, a spacer film 6 of alumina is vapor-deposited on the surface of the slider 1 to about 0.3-0.5mu thickness. Thus, even when the slider 1 and disk are in contact with each other, there is a gap of about 0.3mu between the electrode 2 and metal magnetic film 5 which is a conductor, so no electric discharge is caused and variation in floating quantity is measured excellently even on a metal medium.
