Abstract: PURPOSE:To enable 2 terminals to be connected satisfactorily with small heat capacity, by making extended section of an element electrode an electrode terminal and connecting this terminal directly to a mold type or a metal can type preamplifier's terminal. CONSTITUTION:Electrodes 2 and 2' are soldered onto both sides of a high molecular pyroelectric and piezoelectric element 1 and electrodes 3 and 4 are soldered onto extended sections of the electrodes 2 and 2'. The element 1 is provided on a substrate 5, the substrate 5 is provided on a mold type or metal can type FET6, and the FET6 is provided on a stem 7. By using this structure, a gate terminal 8 of the FET6 is directly bent and connected to the terminal 3 using electroconductive paint 9, and a grounding terminal 10 of the FET6 is also connected to the terminal 4 in the same manner. In this case, of an amount of the heat applied to the element 1, rate of escape through the electrode terminal is very small even through the electrode terminal's width is large since the film thickness is small, and even if the preamplifier terminal's diameter were to be large, the rate of escape of the heat is also small.

Title: Water treatment apparatus by aquatic plant
Inventor: SUZUKI TOKUO
IPC: C02F3/32
Filed: 1988-03-08
Abstract: PURPOSE:To enhance the activity of rooting zone bacteria by effectively bonding nutriments in inflow raw water to the water roots of an aquatic plant by a method wherein a plurality of reticulated containers having the aquatic plate taking root thereinto are provided in a water flow passage so as to be set to one flow wall of said flow passage in a freely detachable manner and a main flow passage is formed between the flow walls on the opposite side of said flow passage to generate turblent flow between the containers. CONSTITUTION:When raw water is allowed to flow in a water flow passage 11, the flow of raw water viewed from the upper part of the water flow passage 11 passes through the main flow passage 41 formed between flow walls of the water flow passage opposed to the reticulated containers 15 of an aquatic plant 15 mounted to one flow wall 40 of the water flow passage and a part of the flow enters between the containers 15 to generate a vortex stream 27. Since this vortex stream falls gently, the colony of rooting zone bacteria already formed to the aquatic plant 16 is not released and nutriments in raw water are properly bonded to the water roots 17 of the aquatic plant 15 over the whole thereof. As a result, the activity of rooting zone bacteria is enhanced and the absorption of the nutriments in raw water is effectively promoted and water having transparency enough to permit the growth of fish can be obtained.

Title: Checking method for thin film magnetic head
Inventor: MIYAMOTO NORIFUMI
IPC: G11B5/455
Filed: 1988-03-09
Abstract: PURPOSE:To simplify the check of a defective head that produces the wiggles by applying an energizing magnetic field to the reproduction signal received from a disk from the outside and observing the level of the wiggle as the swell of a reproduced waveform. CONSTITUTION:The signals produced from a signal recorder 6 are recorded on a disk 4 and a read/write changeover switch 5 is set at the read side for execution of a reproducing job. The signals recorded on the disk 4 are converted into electric signals by a magnetic head 1 and sent to a signal reproducing device 7. The device 7 amplifies the received delicate electric signals and shows them on a waveform display device like an oscilloscope, etc. Then the wiggle level is specified by observing a fact that the wiggle component contained the reproduction signal of the head 1 produced from an external energizing signal of a 1st high frequency having a fixed amplitude runs up the slope of the reproduction signal by an external energizing signal of a 2nd low frequency and changes the envelope of a reproduced waveform. Thus it is possible to specify the wiggle component produced from a defective head and to check the quality of a thin film magnetic head.

Filed: 1980-04-24
Abstract: PURPOSE:To hold stability by changing the speed of an actuator properly with the sum signal of a manual speed control signal and arithmetic speed control signal when correcting track control manually in automatic operation. CONSTITUTION:When switch 6' is closed on arrival of interruption signal (t) at switch 6' in automatic operation to connect adders 5 and 14 together, operating input equipment 2 generates interruption signal S to open switch 13. Input signal (w) to adder 5 is therefore cut off and output v'=k1v of input signal (v) to operator 15 is supplied to adder 14. Manual speed control signal (x) outputted from input equipment 2 is supplied to operator 16 to obtain x'=k2x, which is inputted to the other terminal of adder 14. Consequently, output (u) of adder 14 is the sum signal of signals v' and x' and the flow rate that corresponds to output (u) is outputted from flow-rate control mechanism 10 to hold a stable state.

Filed: 1979-05-01
Abstract: PURPOSE:To laminate smoothly without flaw, not causing scratch flaw and other defects on the billets, by letting off billets onto biling device to laminate while forming water film between biler unit and billet or between billets. CONSTITUTION:A billet 1 stopped in the let-off position of a conveying table 2 is pushed out by an advance command signal from a pusher unit 3. In cooperation with the advance command signal of the unit 3, an electric water valve 10 linked to an electric circuit is opened by a slight extent by means of a first valve control device 11. That is, by opening this valve 10, water is sprinkled in parabolic form onto a biling device 5 when letting off the billet 1 of the initial loading, and onto the billet 1 when the billet of the previous loading is positioned on the device 5. Several seconds later, the value 10 is fully opened by a second valve control device 12, and the water is violently injected into the lower surface of the moving billet 1 by means of the unit 3. Thus, the billet 1 is allowed to slide smoothly while perfect water film is being formed on the sliding surface, and is pushed onto the device 5, and the valve 10 is closed at the same time to return the unit 3 to the waiting position.
