Title: Driving method for limit current type gas concentration sensor
Inventor: KURUMIYA YOICHI
IPC: G01N27/41
Filed: 1988-08-05
Abstract: PURPOSE:To prevent a sensor from entering a runaway state while maintaining a wide measurable range of gas concentration by stopping a rise in monitor voltage above a specific output current value and holding the voltage constant. CONSTITUTION:A reference power source E1 generates the sensor monitor voltage Vm to be applied to the sensor S and a reference power source E2 determines the maximum value of the sensor monitor voltage Vm. Further, operational amplifiers OP1 and OP2 convert the output current of the sensor S into a voltage signal. Then an amplifier OP2 feeds the voltage signals converted by the amplifiers OP1 and OP2 back through a circuit M to amplify the monitor voltage Vm. When the output of the amplifier OP3 is smaller than the voltage E2 of the reference power source, the output of an amplifier OP4 outputs a voltage as high as the output of the amplifier OP3 and when the output of the amplifier OP3 is larger than the voltage E2 of the reference voltage, the output of the amplifier OP4 is the voltage E2. Then the output of the amplifier OP2 is sent to an output amplifiers L and measured as the output current of the sensor S.

Title: Objective driving device
Inventor: HAMAOKA TAKASHI
IPC: G11B7/09
Filed: 1985-09-06
Abstract: PURPOSE:To reduce a device in size and weight on the whole by providing an objective with a piezoelectric element which is driven in a tracking direction at right angles of the optical axis of the lens. CONSTITUTION:Piezoelectric elements 41 and 41' are fitted on surfaces of leaf springs 23 and 24 for tracking. When a voltage is applied to those piezoelectric elements, the leaf springs 23 and 24 curve and a lens holding cylinder 22 moves correspondingly at right angles to the optical axis, i.e. in a direction B-B'. For the purpose, the voltage applied to the piezoelectric elements 41 and 41' is controlled to perform tracking control. Therefore, a lens supported on the two leaf springs 23 and 24 is allowed to move only in the tracking direction (Y direction) in a plane perpendicular to the optical axis, and never moves in other directions, e.g. X direction, so excellent tracking corrections are made. Further, the optical axis does not slants during tracking operation.

IPC: G11B11/105
Filed: 1986-08-21
Abstract: PURPOSE:To obtain a magneto-optical recording medium which is improved in reading out performance and adhesiveness and has excellent reliability by using a film formed by adding Ti to SiO as a dielectric film. CONSTITUTION:The dielectric film formed by adding Ti to SiO is used as the dielectric film to be laminated on a magneto-optical recording layer. The refractive index of the dielectric film can be increased to >=2.0 by adjusting the amt. of the Ti to be added thereto, by which the kerr rotating angle of the magneto- optical recording medium can be increased and the C/N improved. The coercive force of the magneto-optical recording medium formed by using such dielectric film is less varied as the amt. of the Ti to be added increases; therefore, the corrosion resistance hence the protective effect are improved. Since the dielectric film has the high adhesiveness to the substrate of magnetic recording layer, the dielectric film is highly reliable as the protective film.

Title: Production of coagulated latex
Inventor: MAEDA TETSUO
IPC: C08C1/00
Filed: 1983-10-21
Abstract: PURPOSE:To produce a coagulated latex free of impurities such as a precipitant or emulsifier-derived products, by adding a specified precipitant to an emulsion polymer latex obtained by using a carboxylate emulsifier and neutralizing it. CONSTITUTION:In the production of a coagulated latex from a polymer latex (e.g., ABS resin latex) obtained by emulsion polymerization by using an emulsifier in which the hydrophilic group is a carboxylate (e.g., potassium stearate), the polymer latex is precipitated by adding thereto a precipitant containing 0.05-50 equivalent, in relation to the carboxylate groups of the emulsifier, of an acid (e.g., hydrochloric acid) and 0.05-20 equivalent of a water-soluble salt of a bi- or trivalent metal (e.g., CaCl2 or AlCl3), and then neutralized by adding 0.5-5 equivalent, in relation to the added acid, of a base (e.g., NaOH). The polymer thus produced is freed from problems such as discoloration, corrosion of a die or the like, during molding, because the carboxylic acids which are emulsifier derivatives formed from the emulsifier and the precipitant are stabilized and the impurity content of the final polymer is reduced because of a small amount of the added polyvalent metal salt.

Title: Formation of sealing frame for printed circuit board

IPC: H05K3/28
Filed: 1986-08-25
Abstract: PURPOSE:To streamline the formation work of sealing frames by forming sealing frames with a screen process printing at prescribed places of a printed interconnection substrate. CONSTITUTION:A screen process printing form 9 is fixed to fit a sealing frame with a place to be formed. Once ink 14 of epoxy resin is placed on a substrate and is flattened with a doctor knife 15, its ink 14 is pressed in a templet opening 10 of the printing form 9. If the printing form 9 is bent and is pressed on the substrate 1 and then a squeegee 16 is moved laterally along the upper surface of the printing form 9, ink 14 adheres to the substrate 1. when the opening 10 separates to rise from the substrate surface, ink 14 is left on the substrate 1 and then the sealing frames consisting of uncured epoxy resin are formed at the prescribed places on the substrate 1. Eventually uncured epoxy resin is treated with heat curing and the substrate 1 equipped with the sealing frames 7 is formed. Thus, this approach helps streamline the formation work of the sealing frames.
