Title: Piezoelectric high-molecular compound material
Inventor: KADOOKA TSUTOMU
IPC: H01L41/18
Filed: 1979-02-20
Abstract: PURPOSE: To heighten ferroelectric and piezoelectric properties, by performing prescribed treatment to set the grain size of ferroelectric porcelain powder and blending the powder with a high-molecular substance.  
     CONSTITUTION: Raw material powder is prepared according to a desired ferroelectric porcelain composition. The powder is synthesized by heated solid reaction or sintering treatment. The synthesized material is pulverized to a desired grain size. The pulverized material is annealed under an atmosphere of higher oxygen concentration the air and then chemically etched. Innumerable domains and asymmetric phases caused by the pulverization are improved by the annealing. Single domain fine round crystal of arranged grain size is obtained by the etching. The effect of the etching can be heightened by adding mechanical dissolution such as in-liquid stirring. The single domain fine crystal is blended with a prescribed quantity of a high-molecular substance. The mixture is polarized, thereby attaining high ferroelectric and piezoelectric properties which are easily arranged in the direction of electric field because the grain size of the mixture is uniform.

Title: Controller
Inventor: NAGAO TOSHIAKI
IPC: G05B11/00
Filed: 1986-01-30
Abstract: PURPOSE:To set a complicated function by means of a small number of keys on the panel surface at the time of input operation, by switching functions based on the pushing time of keys. CONSTITUTION:A timer of a RAM 7 is started when a function key FUN is pushed. This timer is set for full 3sec for example, and the time-up state of the timer is checked. When the timer is not set under a time-up state, the special manual output is displayed in a character display area of a display part 5. Thus the output of a contact level is secured to set an operating amount regardless of the control contents. If the key FUN is pushed for 3sec or longer, the special limiter display is given to the character display area of the part 5 and the upper limit of the manipulated variable that changes by the control state is set previously.

IPC: H05B33/14
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide an organic light emitting diode having a transparent cathode structure. SOLUTION: This structure has a metal thin film 64 having a low work function, and this metal thin film 64 is brought into direct contact with an electron transport layer 62 and is covered with a layer 66 of a broad band gap semiconductor. Since calcium has relatively high optical energy transmittance, and has the ability to form an electron injection contact having excellent properties for an organic substance, the metal forming the metal thin film 64 is preferably made of calcium. In addition, ZnSe, ZnS or their alloys exhibit excellent conductivity in a direction parallel to emission light, and has the ability to protect a low work function metal and an organic film in a lower layer, and is transparent for the emission light. Therefore, a semiconductor forming the semiconductor layer 66 is preferably selected from a group consisting of ZnSe, ZnS or their alloys.

Title: Waste water treatment by activated sludge method
Inventor: NAGASAKI YOSHIMI
IPC: C02F3/00
Filed: 1988-02-01
Abstract: PURPOSE:To decrease aeration rates and to stably clean waste water over a long period of time by dividing an aeration tank to 3 tanks and specifying the aeration rates with respect to the liquid volumes in the respective tanks. CONSTITUTION:The aeration tank is divided to the 3 tanks in an activated sludge treatment of industrial waste water, living waste water, etc. Sludge bacteria absorb the org. matter in the waste water and partly oxidize and decompose the org. matter in the front tank. The sludge bacteria decompose and metabolize the adsorbed org. matter in the middle tank and the sludge bacteria are activated in the rear tank. The aeration rates are, thereupon, adjusted to 0.5-0.8 in the front tank, 0.1-0.4 in the middle tank and 0.1-0.3 in the rear tank per minute in volume ratio with respect to the liquid volumes in the tanks. The pH of the liquids in the tanks is adjusted to >=6.0 and <=7.0. The pH in the front tank is adjusted to the lowest value, i.e., about 6.0-6.5, the pH in the middle tank to about 6.0-6.7, and the pH in the rear tank to about 6.3-7.0. The aeration rates are thus lowered, by which the cost is reduced and the cleaning of the waste water is stably executed over a long period of time.

Title: Measurement system for emerging frequency of instruction
Inventor: CHINJU MASAAKI
IPC: G06F11/34
Filed: 1987-01-31
Abstract: PURPOSE:To facilitate the measurement of the emerging frequency of instructions by providing a means to a CPU to apply an interruption to a service processor every time an instruction is carried out together with a means which stops the CPU via the service processor, and a means which reads out the inside range of the CPU. CONSTITUTION:When an interruption signal 100 received from a CPU 1 is detected, an interruption detecting circuit 20 starts a state control circuit 21 and a read control circuit 22 and stops the operation of the CPU 1 for each execution of an instruction. When the operation of the CPU 1 is stopped, the circuit 22 reads an instruction code out of an executing instruction storing circuit 14 via a data line 103 and transfers it to a counter circuit 23. Thus the circuit 21 starts the CPU 1 again. The circuit 23 discriminates the instruction code of the received data and counts up the emerging frequency of each instruction to hold this count value. Thus the emerging frequency of instructions can be measured.

Title: Dual port memory control circuit
Inventor: YAMAZAKI YOSHIKAZU
IPC: G06F12/00
Filed: 1983-02-10
Abstract: PURPOSE:To fetch transfer requests for writing and reading which are generates asynchronously at the limit speed of circuit elements by controlling transfer requests for writing and reading by combinations of gates without using any clock pulses. CONSTITUTION:A read request pulse RP12 is inputted lagging behind a write request pulse WP11. A delay FF13 is set by the WP11 to generate an output (a) of ''1'', and a bistable FF14 is stored with the output (c) of the 2nd pulse generator 17 at the same time. Consequently, while outputs (a) and (b) satisfy the AND condition, the 1st pulse generator 19 outputs a memory write pulse MWP16. On the other hand, the pulse generator 17 is triggered by the RP12 to generate the pulse (c), and a memory read pulse MRP18 is outputted from a gate G2. Thus, a latch 14 performs switching between the MWP and MRP and the pulse (c) is twice as wide as the pulse 16, so even when the WP11 and RP12 are inputted at the same time and the latch 14 gives the write request priority, a normal time is secured without any overlap between the MWP and MRP.
