Title: W/o emulsion ink
Inventor: KOIZUMI MINORU
IPC: C09D11/023
Filed: 1992-10-16
Abstract: PURPOSE:To obtain an ink excellent in, e.g. fixability to paper by forming a WHO emulsion which consists of an oil phase and a water phase at a specified weight ratio and of which the oil phase contains a specified aluminum chelate. CONSTITUTION:A W/O emulsion is prepared which consists of about 10-50wt.% oil phase and about 90-50wt.% water phase and of which the oil phase contains at least one of aluminum chelates of formulas I, II and III (wherein R is alkyl). Necessary additives such as a pigment, a dispersant and an emulsifier are incorporated into the oil phase, while necessary additives such as an antiseptic and an antioxidant are incorporated into the water phase, thus producing the ink. Because of the incorporation of the aluminum chelate into the oil phase, the pigment dispersed in the oil phase can be kept remarkably fine. Accordingly, the pigment penetrates together with the vehicle into the minute pores of paper, and scarcely any pigment will remain on the paper and the release by rubbing can be remarkably reduced.

CONSTITUTION:As the result of the erasure of recording over three times, picking 35 is generated in the vicinity of the downstream ends of all of small regions 34c in the release direction thereof but, since the width of each of the small regions 34 is small, the pickings 35 in the respective small regions 34c overlap each other only within a small range and therefore, the damage to the paper of picking 35 is reduced. Since the recording 32 in the whole of the recording erasing region 33b corresponding to one section of printing is erased, even when paper feed accuracy is bad, a part of the recording 32 on the paper is not left. Since erasure is performed at every erasure unit consisting of a plurality of the small regions spaced apart from each other over three times, possibility such that the temp. of a heating element continuing the generation of heat reaches proper temp. or higher is eliminated and the contamination of the paper due to the melting of the ink of an ink ribbon is prevented.

Title: Electric power source breaker
Inventor: SHIBUYA JUNICHIRO
IPC: H02H3/00
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To allow an operator who recognizes the information of cutting off a load current to take a proper action to a load by starting measuring time in response to a thermal relay, stopping the operation of a buzzer after a predetermined time elapses and cutting off a breaker. SOLUTION: When a load current exceeds the predetermined value of a thermal relay TH, the thermal relay closes a contact TH-1. Therefore, a liner relay T1 is connected to electric power source lines 2, 3, and a normally-closed contact T1-1 maintains its close state during a set predetermined time and a buzzer goes on. During the operation of a buzzer BZ, namely, during a predetermined period of time of the liner relay T1, an operator cuts off a breaker B1 to disconnect a load LD1 from the electric power source lines 2, 3, thereby opening the contact TH-1 to return it to an initial normal state. The operation of disconnecting the breaker B1 is informed to the operator in advance by the operation of the buzzer BZ during the set predetermined period of time.

Title: Optical pickup
Inventor: ITO KENICHI
IPC: G11B7/09
Filed: 1988-12-06
Abstract: PURPOSE:To improve the accuracy of the tracking position control by forming a reference point which moves together with a condenser lens in a united state in a plane perpendicular to the optical axis passing through a point almost equal to the principal point of the condenser lens and providing a means which detects the position of the condenser lens to the surface of a recording medium by detecting the displacement of the reference point in the direction perpendicular to the optical axis of the condenser lens. CONSTITUTION:The height of the principal point of an object lens 1 is made coincident with the height of the center of the opening section 5a of a light shielding member 5 and centers of a light source 6 and a bisected photodetector 7 are made coincident with the center of the section 5a in Y direction. Accordingly, when a lens holder 2 makes parallel displacement in X direction, the position of the principal point of the lens 1 and sections 5a of the member 5 also make equivalent displacement in X direction and, moreover, even when the holder 2 makes rolling around Y axis, the principal point of the lens 1 and section 5a make equivalent displacement in X direction. Therefore, the accuracy of the tracking position control can be improved, since the displacement of a light spot on a recording medium can be detected accurately even when the holder 2 moves with rolling.

IPC: G01N21/27
Filed: 1993-11-15
Abstract: PURPOSE:To make it possible to evaluate the taste of rice based on the luminance and the content of amylose without relying on the feeling of human being. CONSTITUTION:The content of amylose of rice is measured and the image of cooking rice is picked up. The image is split into pixels and the luminance of each pixel is measured for three primary color lights of R, G, B. The luminance value of each pixel based on the B color light is then summed for upper twenty values to determine an accumulated luminance value of B color which is employed, along with the content of amylose, in the evaluation of taste. This method realizes highly accurate objective evaluation of the taste of rice and provides excellent voiumetric processing capacity for analytic evaluation.
