Title: System for culturing aquarium fishes
Inventor: NAKAMURA TAKASHI
IPC: A01K63/04
Filed: 1993-08-31
Abstract: PURPOSE:To provide a system which can safely culture aquarium fishes without change in the optimal operation conditions which have been initially selected and set to, even when children innocently touch the keys on the operation panel because various selected and set keys are made it possible to be locked. CONSTITUTION:At first, Individual selection and setting keys such as the key for setting the water temperature or the operation-initiating and stopping key are operated to select and set the operation conditions, then these keys are locked by means of the key-locking key 16 so that the key operations thereafter may be canceled to keep the initial optimal operation conditions. Further, after the key operations are read with the arithmetic unit in the controller 2, depending on the readings, the culturing water circulation unit 3, the thermostat unit 4, the sterilization unit 5 and others are controlled to circulate the culture water in the tank 7 through the cleaning unit 8, the thermostat unit 4 and the sterilization unit 5 whereby the optimal conditions for culturing aquarium fishes are maintained.
Patent JP-H0288297-A (JP)
Title: Memory card
Inventor: SUKAI HIROSHI
IPC: B42D15/10
Filed: 1988-09-26
Abstract: PURPOSE:To reduce a force for inserting/extracting a memory card to/from a connector and make it constant by a method wherein a gold plating condition of a bonding part is made different from that of a terminal part. CONSTITUTION:The surface condition of a gold plating 1 is smoothened. Then, irregularities on the surface of the gold plating 1 is reduced and, thereby, a ratio that a nickel 3 as a primary coat may be exposed is reduced. Moreover, since a ratio that fine dust and dirt may invade into the recessed parts is reduced and, thus, the surface of a terminal can be kept clean, an insertion/ extraction force is made constant. Therefore, the more smooth surface condition of the terminal part enables the more effective action. In addition, the terminal part is hard-plated, whereby a repeated insertion/extraction to/from the connector hardly causes the gold plating to be released or deformed in the surface condition, and the insertion/extraction force becomes more constant and smaller.

SOLUTION: After cooling wind from the outside of an engine compartment is passed through a cooling wind intake, entered in the engine compartment, and passed through a heat exchanger 6, cooling wind is throttled by a guide plate 8 and entered in a cooling fan. After that, cooling wind blown off to the rear of the cooling fan cools an engine and an oil pan, and exhausted from a cooling wind exhaust opening. In this case, an approximately annular sound absorbing material 12 is arranged on the impeller 14a side inner wall surface of a guide plate 8 arranged between the heat exchanger 6 and the impeller 14a of the cooling fan.  Hereby, when generated sound 50a from the impeller 14a is reflected by the heat exchanger 6 and reflected sound 50b is reflected again by the sound absorbing material 12, a component of sound in a predetermined frequency band is absorbed by the sound absorbing material 12, so that the amplitude of re-reflected sound 50c is damped.

Abstract: PROBLEM TO BE SOLVED: To perform the effective serial communication according to the load situation, etc., by selecting a communication line in time division to communicate with a prescribed communication IC based on the contents of connection information that is set to a selection register. SOLUTION: A serial communication control part 460 transfers the data of a data register 0 contained in a communication controller 401 to a shift register 122 via a transmission buffer 121. At this time, the part 460 reads out the information on the connection state set at a selection register 462 and decides based on the read information that a communication IC 402 of address 0 is connected to a communication line 410 having a communication IC 403 of address 4 as its termination. Thus, a selector 461 selects the line 410. Then a clock (CLK) and the data (DATA) are outputted to the line 410. The communication is performed with the IC 402 synchronously with the CLK and accordingly the DATA are sent to the IC 402.
