Title: Current output device
Inventor: NOZAKI KIYOTAKA
IPC: G11B5/027
Filed: 1989-04-24
Abstract: PURPOSE:To maintain the intensity of magnetization of a recording medium within a prescribed value by providing a resistor and a variable amplifier converting an amplitude of the current supplied from a current output device to coil in response to an input signal into a voltage amplitude. CONSTITUTION:A resistor 6 is connected in series with a coil 4, and an amplitude of a current supplied from a current output device 3 into the coil 4 is converted into a voltage amplitude by the resistor 6. The voltage is inputted to a current output amplitude detector 7, in which the voltage is compared with a reference voltage of a reference power supply 8, and an error signal is outputted from the detector 7 to a variable amplifier 9. The amplifier 9 varies the amplification factor in response to the error signal to maintain the amplitude of the input signal inputted from an input terminal 1 within a prescribed value and the result is outputted to the output device 3. Since the input signal within a prescribed amplitude is always inputted to the output device 3, even when the amplitude of the input signal inputted to the terminal 1 is changed or the inductance of the coil 4 is changed, the current output amplitude supplied to the coil 4 is kept within a prescribed value. Thus, the intensity of the magnetization of a recording medium is kept within a prescribed value.

Filed: 1994-05-19
Abstract: PURPOSE:To attain the increasing of recording density by forming marks while changing widths and dimensions of marks according to recording states of adjacent track parts formed adjacently and canceling the crosstalk at the time of a reproducing. CONSTITUTION:When the recording is started, channel bits are successively transferred from a shift register (an SR) 1 to an FIFO memory 4, an SR 2, an FIFO memory 5 and an SR 3 according to an external clock. Then, effective lengths of memories 4, 5 are set so that bits (m+1)th, mth, (m-1)th on respective tracks (n+1)th, nth, (n-1)th on a recording medium 9 are respectively held in respective registers a, b, c of SRs 1 to 3, Thus, the circumferential information of bits to be recorded held in the register 2b are formed in a register group other than the register 2b. A PWM modulator 6 adds channel bit values held by registers 1a to 1c, 2a, 2c, 3a to 3c while giving weights to them so as to cancel the crosstalk to modulate the pulse width of the light beam of an optical system and the recording is performed on a medium 9.

Title: Method for controlling plowing depth
Inventor: TAMAI SEISHIN
IPC: A01B63/00
Filed: 1987-04-28
Abstract: PURPOSE:To prevent deep plowing in starting tillage by decreasing the set plowing depth in starting the tillage in plowing depth control. CONSTITUTION:Plowing depth control is carried out from a higher position of a tiller in starting tillage by a CPU 15 based on detection with a plowing depth sensor 2 using a shallower plowing depth than a given plowing depth set by a position setter 27 as the target by hydraulic operation. When the plowing depth attains a shallow value, plowing depth control is performed by the given plowing depth. When a car body is advanced, control for keeping the given plowing depth is carried out. As a result, since the position of expanded and softened after the tiller can be detected in starting the forward tillage, a greater plowing depth than that required is not provided.

Title: Compile method for c++ program and compiler
Inventor: NACKMAN LEE RICHARD
IPC: G06F9/45
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To dispense without the other sequencing of a forward declaration or a defining declaration by executing the initial sweeping of a source code for each declaration at a time to obtain a declaration. SOLUTION: A source code is syntax-analyzed for each declaration at a time. A declaration which can not syntax-analyzed is left in a following path. Each path stores information related with a type name, variable, and function in program. This information includes subordinativeness, that is, a name declared by a certain declaration is used by another declaration. Only a class T is syntax-analyzed in the initial path of this program. The types of the function and the variable are syntax-analyzed in the second path. A variable initializer and the function body are syntax-analyzed in the third path. Thus, the program can be syntax-analyzed without any manually type declaration or sequence in a plurality of paths.

Title: Data transmitting system
Inventor: OGAWA KENJI
IPC: H04L25/02
Filed: 1981-07-06
Abstract: PURPOSE:To reduce the number of using timers in a transmitting device on the data sending side ina data transmitting method between two transmitting devices by setting the timing for reading data in the data receiving side to the decay time of a reading command. CONSTITUTION:A transmitting device 1 sends out data and a reducing command to a transmitting device 2 simultaneously from a time t0. The reading command is outputted until a time t1 by the control of a timer. Since detecting the decay of the reading command at the time t1, the transmitting device 2 reads data and sends a response at a time t3. The transmitting device 1 receives the response after the response time t3 and sends data at a time t4, so that the sequency of data transmission is completed. Since the transmitting device 1 starts the sending of the reading command at the same time as the sending of data, only the timer regulating the time t2 is utilized.

Abstract: PURPOSE: In the treatment of grains or oil cakes with aluminum phosphide, the reagent is forced circulation with the air that is controlled in the temperature and humidity, thus killing insects effeciently.  
     CONSTITUTION: Grains or oil cakes or the like are put into tightly sealed vessels, a prescribed amount of an aluminum phosphide preparation is charged in the vessel, then the air that is controlled in the temperature and humidity is forced circulation to kill insects in them. The temperature of the air is 15W30°C and relative humidity is over 30%.
