IPC: G11B7/26
Filed: 1986-11-06
Abstract: PURPOSE:To permit production of an optical recording medium having high reliability with high productivity while preventing deformation of a substrate by the heat at the time of sealing and erosion of a recording layer by heating and melting only the thermoplastic sealing material by laser light and sealing the end face of the recording medium. CONSTITUTION:The laser light 3 is condensed by an objective lens 4 and is projected to the sealing material 2 imposed on the end face of the recording medium 1 formed by sticking two sheets of the substrates, on at least one sheet of which the recording layer is formed by the conventional method, while said medium is rotated. The sealing of the inside circumference of the medium 1 is executed by preliminarily forming the sealing material 2 to the shape conforming to said inside circumference and projecting the laser light 3 thereto in the same manner as for the outside circumference. Inorg. materials such as low melting glass and ultrasonic solder which can be melted by the heat of the laser light are adequate as the sealing material 2. The end face of the recording medium is sealed by condensing the laser light and locally heating only the thermoplastic sealing material and, therefore, no damages are given to the substrate and the recording layer. The sealing in the time shorter than for a thermosetting sealing material is possible as the thermoplastic material is used.

IPC: B41J2/045
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To maintain a discharge performance for ink drops stably and at the same time improve a driving frequency. SOLUTION: A first driving signal S1 rapidly changes a volume of a pressure generation chamber thereby discharging ink drops, while a second driving signal S2 changes the volume of the pressure generation chamber by a degree not to discharge ink drops.

IPC: G01P15/09
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To enable accurate direct detection of an angular acceleration in a specific direction in a relatively simple constitution using a semiconductor sensor of a single structure. SOLUTION: Components of accelerations and angular accelerations in other directions acting to four acceleration sensor elements 1-4 than in a Y-axis rotation direction are offset.

Therefore, only a Y-axis rotation component can be detected by this angular acceleration sensor. In the equation, R1-R4 are piezoelectric elements (piezoelectric resistors) of the sensor elements 1-4.

Title: Water-sealed pump
Inventor: YASUDA MOTONORI
IPC: F04C19/00
Filed: 1984-12-14
Abstract: PURPOSE:To prevent change of suction capacity even if the temperature of supply water to a water-sealed pump is changed, by a method wherein a regulating valve, regulating a mixture ratio of a reflux water amount to a new feed water amount according to the degree of vacuum on the suction side, is located in a reflux piping running from a gas moisture content separator. CONSTITUTION:A reflux piping 3 is coupled to a gas moisture content separator 2 on the discharge side of a water-sealed pump 1, and a regulating valve 6, regulating a mixture ratio of a reflux water amount to a pump to a new feed water amount through detection of a pressure on the suction side by means of a pressure switch 11, is situated in the piping. When a pressure on the suction side is decreased to lower than a specified value, the regulating valve 6 increases a ratio of reflux water, but since the temperature of the reflux water is relatively high, suction performance of the pump is automatically deteriorated. When suction performance of the pump is excessively lowered due to an excessive increase in the temperature of pump working water, an amount of new feed water fed through a line 5 is increased with the aid of a regulating valve 6 to improve suction performance of the pump.
