Title: Frequency discriminating circuit
Inventor: TAKEMOTO SATORU
IPC: G01R23/14
Filed: 1985-01-31
Abstract: PURPOSE:To identify many frequencies and to prevent the transient response by a tone burst wave by multiplying a reference signal and input signal by a multiplier and detecting the frequency desired to be identified. CONSTITUTION:The input voltage of an unknown frequency fx is normalized by an AGC circuit 1 and the reference voltage of the frequency fk is generated from a reference frequency generator 7. Both voltages are multiplied by the multiplier 4 and are integrated by an integrator 5. The signal V1 outputted from the integrator is ¦V1¦>1/2 if fx=fk. The output signal of an absolute value circuit 6 is inputted to a comparator 8 from which the signal is outputted when a certain value or above is attained. The identification of the many frequencies with the simple constitution is thus made possible. LSI is made easy and the need for using and active filter as in the conventional practice is eliminated.

Title: Herbicide composition
Inventor: SUZUKI KOICHI
IPC: A01N37/22
Filed: 1991-02-08
Abstract: PURPOSE:To provide a herbicide composition containing two kinds of known herbicidal components, having synergistically improved herbicidal effect of each component, effective at a low rate of application and capable of completely controlling annual and perennial weeds at a low rate of application without causing phytotoxicity to corn. CONSTITUTION:The objective composition contains (A) the compound of formula I and (B) one or more kinds of compounds selected from alachlor, metolachlor and acetochlor of formula II to formula IV. The amount of the component A is 0.001-10 pts.wt., preferably 0.01-1 pt.wt. per 1 pt.wt. of the component B. The herbicidal activity of the composition is not a simple addition but a synergism of the activities of the components. The composition is effective at a low rate of application, i.e., 1g to 1kg/ha of A and 10g to 5kg/ha of B, preferably 10g to 5kg/ha of A and 50g to 3kg/ha of B. Although the composition is effective by the foliar treatment after germination, it is preferable to use the composition by soil treatment before germination. It can be applied to various crops other than corn and other agricultural and horticultural fields and uncultivated field to develop remarkable economic effect.

Title: Movable-blade compressor
Inventor: HAYASE ISAO
IPC: F04C18/00
Filed: 1982-02-08
Abstract: PURPOSE:To reduce the resistance to the intake flow, by forming an intake passage to extend helically in the direction of rotation of a rotor. CONSTITUTION:A movable-blade compressor of this invention comprises a rotor, vanes fixed to the rotor, a cylinder surrounding the rotor, side plates disposed on both sides of the cylinder for defining a compression chamber, and an intake passage 30 formed at least in one of the side plates for introducing a suction gas. Since the spiral intake passage 30 extended from an intake port 32 is shaped such that its sectional area is not increased drastically, the energy loss is reduced. Further, since the intake passage 30 is wound in the direction of rotation of the rotor, a coolant gas introduced into the passage 30 from the intake port 30 is formed into a swirl flowing in the direction of rotation of the rotor and introduced smoothly into a compression chamber via suction ports 34  formed in the side plate, without changing the direction of the swirl flow. Therefore, it is enabled to reduce the resistance acted to the fluid flow before the coolant gas is introduced into the compression chamber.

Title: Semiconductor device
Inventor: NISHIMURA EITETSU
IPC: H01L21/3205
Filed: 1984-02-03
Abstract: PURPOSE:To offer the structure of preventing the corrosion of an internal integrated circuit even when water penetrates through a passivation film window of positioning pattern, by surrounding the positioning pattern with a metal layer in a semiconductor integrated circuit sealed with plastic. CONSTITUTION:It is the same way as conventional that the positioning pattern 5 is formed in the passivation film 1, but the metal layer 6 encircling this positioning pattern is formed between the passivation film 1 and an interlayer insulation film 3. Thereby, water penetrating through this pattern 5 flows along the interface between the films 1 and 3 to the metal layer 6 before reaching an Al wiring 2, then corroding this layer. Therefore, effects of outer water are not exerted on the Al wiring 2 of the internal integrated circuit.

Filed: 1988-01-28
Abstract: PURPOSE:To improve operability by providing a means which simultaneously controls the sources of two equipments by means of the operation of the power switch of one of the devices and a means which independently controls one of the equipments. CONSTITUTION:When the power switch 2 of a micro computer 1 in an equipment A is depressed, a terminal X comes to a high level, and it is added to the base of a transistor Q2.

Namely, the power of the device B can be on/off-controlled by operating the power switch 2 of the device A only if the common terminal (1) of the switch 5 is set in a position (3). When the common terminal (1) of the switch 5 is set in a position (2), a +B2 voltage is added to the common terminal (1) through a resistance R9, and a transistor Q3 is conducted, whereby the power of the micro computer 4 comes to an on-state. Thus, operability as a single type is given while the titled circuit is a composite type and the powers can individually be controlled.
