Title: Method of preventing red tide
Inventor: KIMOTO KOUTAROU
IPC: C02F1/50
Filed: 1979-10-31
Abstract: PURPOSE: To prevent red tide due to dinoflugellate or the like by using sodium percarbonate without damaging fishes and shellfishes.  
     CONSTITUTION: To the water area where red tide has generated or is anticipated to generate, sodium percarbonate is scattered to prevent the red tide. Althrough, the amount of sodium percarbonate used is different according to the state of red tide generation, weather condition or the like and is not especially limited, a concentration of 10W100ppm suffices four the perishment of dinoflugellate and does not adversely affect fishes and shell fishes. Because sodium precarbonate is decomposed to sodium carbonate which is a component of sea water and water, and change in water quality after use is not induced.

Title: Speed controller for elevator
Inventor: MASASHIRO TAKANOBU
IPC: H02P27/06
Filed: 1988-06-08
Abstract: PURPOSE:To prevent an overcurrent from flowing to a thyristor at the time of its regenerative operation by interrupting an input to a phase control circuit in response to the phase angle of a firing pulse to be applied to a converter and a charging voltage of a smoothing capacitor. CONSTITUTION:If an arrival of the phase angle of a firing pulse at an end stop is judged by monitoring it with a phase monitor 30, a monitor signal 30a is input to a switch 32. If the output command 12a of a speed control calculator 12 becomes a value larger than the voltage signal 13a of a smoothing capacitor 3, the switch 32 prevents the output of a voltage control calculator 14 from increasing. Thus, even if a converter 2 or a phase control circuit 15 is turned OFF to be defective so that a single phase operation occurs, it can prevent an overcurrent from flowing to a thyristor bank at the time of regeneration for forming the converter.

Title: Lead frame
Inventor: ARAI HITOSHI
IPC: H01L23/50
Filed: 1990-05-30
Abstract: PURPOSE:To obtain a lead frame wherein leads are not scattered even if the leads are cut from a frame and a dam bar by providing an insulating frame which is formed on the side inner than a surrounding outer frame and links the leads. CONSTITUTION:A lead frame is constituted in such a way that an outer lead zone 2a of each lead 2 is linked to a frame 1 and an insulating frame 3 which links the outer lead zones 2a on the side inner than the frame 1 is formed. The insulating frame 3 is formed by linking the leads 2 on the inner side of the frame 1 which is the outer frame of the lead frame. Therefore, even if the lead is cut in a position M of the lead 2, the leads 2 are not scattered. The leads 2 are electrically independent after the cutting because of the formation of the linked unitary body at the insulating frame comprising insulating material. Thus, the contact state with another substrate and the like in an inner lead zone 2b of each lead 2 can electrically be tested.

Title: Exhaust cooling system
Inventor: HARADA KENICHI
IPC: F01N3/32
Filed: 1991-06-13
Abstract: PURPOSE:To prevent at least a catalyst out of an oxygen sensor and the catalyst from increasing in temperature so as to keep it in an optimum activating temperature region. CONSTITUTION:There are provided exhaust temperature sensors 24, 25 immediately upstream from an oxygen sensor 23 disposed on an exhaust passage 3 and in an inlet of a catalyst converter 7. Air pipelines 12, 13 for supplying secondary air are opened upstream from the exhaust temperature sensor 24 and upstream from the catalyst converter 7. Communication of the air pipelines 12, 13 with an air pump 15 is changed over by a VSV 14 so that a secondary air supplying position on the exhaust passage 3 can be changed. When an ECU 31 judges that secondary air should be supplied, the opening/closing of the VSV 14 is switched, thus driving the air pump 15. According to a difference between detection temperatures of the exhaust temperature sensors 24, 25 and a target temperature, a discharge air quantity of the air pump 15 is controlled in such a manner that an exhaust temperature is converged to the target temperature, thereby adjusting a secondary air supply quantity. Consequently, the sensor 23 and the converter 7 can be cooled at the target exhaust temperature.

Title: Scrape filter
Inventor: KUROSAWA TADASHI
IPC: G11B15/46
Filed: 1978-11-20
Abstract: PURPOSE: To prevent the production of modulation noise, by fitting wings to the end surface.  
     CONSTITUTION: A plurality of windmill wings 7 are fitted to the end surface of the scrape filter absorbing the vibration of tape 6, located between the erase head 2 and the recording head 4, in contact with the capstans 1. Thus, when the scrape filter 3  turns with the running of the tape 6, the wings 7 turn in air to cause the attenuation force for viscosity resistance to the scrape filter 3. This attenuating force attenuates the vibration of the tape 6 to make smooth modulation characteristics of  the tape recorder. The tape running of tape recorder is kept stable and the production of modulation noise can be avoided.

Title: Brake fluid pressure controller for vehicle
Inventor: WATANABE HIROYUKI
IPC: B60T8/40
Filed: 1990-05-31
Abstract: PURPOSE:To perform a braking operation without entailing any drop in hydraulic rigidity by making an accumulator independent separating it from a piping system connecting a master cylinder and a wheel cylinder together by means of selector operation of a hydraulic source selecting means at the time of normal braking. CONSTITUTION:In slip control at time of starting acceleration, an accumulator F is connected to the inlet side of a transfer control means G by means of selector operation of a hydraulic source changeover means H, and simultaneously connected to the outlet side of a pressure means 1. In addition, the inlet side of this pressure means 1 is connected to a reservoir B of a master cylinder A. Accordingly, the slip control of acceleration takes place after feeding a wheel cylinder D with pressure out of the accumulator F and the pressure means 1. On the other hand, at time of normal braking, the accumulator F is made into a state of being independent by way of separating it from a piping system K connecting the master cylinder A and the wheel cylinder D by means of selector operation of the hydraulic source changeover means H. Then fluid pressure out of the master cylinder A is exerted at once on the wheel cylinder D, through which any drop in hydraulic rigidity is kept back.

Title: Time division multiplex communication system
Inventor: IGARASHI HIRONOBU
IPC: H04J3/00
Filed: 1987-06-08
Abstract: PURPOSE:To prevent an error from being caused in data by generating a switching control signal in synchronism with a frame timing FT or a burst timing BT and generating a fault signal attended with the generation of the switching control signal for a blank bit period. CONSTITUTION:A signal obtained by the operation of a switch 3 is fed to a timing adjusting device 7 to form a signal synchronized with the timing of the frame timing FT and the result is fed to a counter 9 as a switching control signal via an AND gate 8. Since the switching control signal is generated in synchronism with the frame timing FT without fail, chattering attended with the generation of the control signal or voltage fluctuation is generated without fail at a blank bit DC in a frame format even if the switch operation is applied at any point of time. Thus, noise or voltage fluctuation is caused only for the blank bit period as a signal sent from the date transmission circuit 10 and neither noise nor voltage fluctuation is caused in the data transmission period.

Title: Position detector
Inventor: MURAKAMI AZUMA
IPC: G06F3/046
Filed: 1989-06-05
Abstract: PURPOSE:To increase the position detection speed by using a reception circuit holding the value of the induced voltage when the prescribed time shorter than the signal delay time caused by a BPF lapsed after a loop coil is switched. CONSTITUTION:The signal produced by the voltage induced at a tuning circuit 41 of a position pointing device 4 is delayed by a reception circuit 6 by a signal delay time set by a BPF. Then the circuit 6 holds the value of the induced voltage when the prescribed time shorter than the delay time lapsed after the loop coils (11-1)-(11-48) are switched. Thus each loop coil can obtain the induced voltage which is gradually reduced as the distance increases from the position designated by the device 4 with the induced voltage of the loop coil set nearest the designated position. The value of each induced voltage is computed by a processor 7 and the coordinate value is obtained for the position designated by the device 4. Consequently, the position detecting speed is increased even with the use of a BPF having the small width of its frequency band.
