Title: Caught fish life maintaining apparatus for ship
Inventor: YOKOYAMA KAZUYA
IPC: B63B35/26
Filed: 1980-05-10
Abstract: PURPOSE: To prevent the death of the caught fish resulting from the change in temperature and enable it to be brought back being kept alive, by detecting and comparing the temperature of the water in a live well and that of the water in the water area where said fish was caught with each other, and effecting control so that said temperatures are made equal to each other.  
     CONSTITUTION: The temperature of the water in a water area is measured by means of the second sensor 8, while the temperature of the water in a live well 1 is measured by means of the first sensor 2, and both temperatures are compared with each other by means of a comparing circuit 10. The value obtained through the comparison performed by the comparing circuit 10 is amplified by means of an amplifier 11 and sent to a cooling/heating deciding circuit 12. When the temperature of the water in the live well 1 is lower than that of the water in said water area, a heating controlling circuit 14 is operated to actuate and control a heater 4. On the other hand, the temperature of the water in the live well 1 is higher than that of the water in said water area, a cooling controlling circuit 13 is operated to actuate and control a cooler 3. Thus, the temperature of the water in the live well 1 is made constantly equal to that of the water in the water area where the fish was caught, in order to prevent the death of the caught fish.

Title: Screen printing method
Inventor: YOKOYAMA YASUO
IPC: B41F15/40
Filed: 1994-03-31
Abstract: PURPOSE:To enable printing of high resolution to be carried out over a broad area of matter to be printed by a method wherein an attack angle of a squeegee at one end side of a screen on a start point side of transfer is made smaller than that at the other end side of the screen on an end point side of the transfer, and that on the other end side is made larger than that on one end side. CONSTITUTION:A squeegee 3 is transferred at an almost constant attack angle at a middle position of matter 1 to be printed. It is transferred at the attack angle drawing a curve wherein the attack angle on a start point side is smaller than that at the middle position and becomes the larger as the squeegee approaches the more near to the middle position. It is transferred on the end point side at the attack angle drawing a curve wherein the attack angle on the end point side is larger than that at the middle position and becomes larger as the squeegee approaches the end point. That is, when the attack angle of the squeegee 3 is small, a discharge amount of thick film paste 4 increases inversely proportionally to that angle. When the angle is large, since the discharge amount of the paste 4 decreases, blur in printing becomes difficult to be generated even on one end side of a screen 2 being the start point side of transfer of the squeegee 3 wherein blur in printing is easily generated.

Abstract: PURPOSE:To obtain a water-based magnetic fluid which has high saturation magnetization and stable dispersibility by coating the surface of magnetic metal particle with a 1st surfactant adsorptively and then dispersing the product in an aqueous solution containing a 2nd surfactant and a nitrogen compound. CONSTITUTION:A 1st surfactant which causes chemical or physical adsorption onto the surface of a magnetic metal particle in an aqueous solution containing magnetic metal particles such as iron particles (e.g. sodium oleate) is adsorbed onto the surface of the magnetic metal particle. After solid/liquid separation and dehydration, the magnetic metal particles are dispersed in an aqueous solution containing a 2nd surfactant (e.g. sodium dodecylbenzenesulfonate) and a nitrogen compound (e.g. tetramethylammonium). Thus, a water-based magnetic fluid containing magnetic metal particles which have adsorptively been coated with double layers each consisting of the 1st surfactant and the 2nd surfactant is obtained. The magnetic fluid is suitable used for various applications in which an organic base magnetic fluid cannot be used.

Filed: 1995-03-22
Abstract: PURPOSE: To sufficiently reduce a moving speed of a head when a light beam is moved to a required track by adding the constitution for outputting a brake signal when it is judged that the light beam is moved to the required track. CONSTITUTION: A speed detection circuit 6 detects the moving speed of the head 2 by measuring a period of a tracking error signal. Detected moving speed information is outputted to a speed control circuit 8. A counter 7 counts the number of track traverse of the light beam 3 by counting the tracking error signal. The speed control circuit 8 compares a target speed value according to the number of residual tracks sent from the counter with the detected speed value sent from the speed detection circuit 6, and outputs a drive signal to a driver 5 so that the moving speed of the head 2 becomes the target speed. When a tracking servo loop is turned on, the light beam 3 follows up the track (required track) irradiated at the time.
