Filed: 1992-06-02
Abstract: PURPOSE:To improve the efficiency of a soldering operation by extremely easily putting sprayers into a clean state without spending much labor and time. CONSTITUTION:A flux supply piping 21 for feeding a flux into a flux tank 7 is provided. A diluent supply piping 23 for feeding a diluent to the flux tank 7 is provided. A selector valve 22 for selectively switching the respective flow passages of the flux supply piping 21 and the diluent supply piping 23 to the flux tank 7 is provided.

Abstract: PURPOSE:To prevent the dissolution of a seed crystal in a process for growing a diamond crystal in a reactor having a temperature gradient under high temperature and pressure taking advantage of the solubility difference of carbon to the solvent metal, by separating the solvent metal from the seed crystal with a covering layer composed of a specific metal compound.

Title: Semiconductor memory device
Inventor: NAKADA YOSHIRO
IPC: G11C17/00
Filed: 1986-06-18
Abstract: PURPOSE:To obtain a large capacity high density memory device in which the recording quantity of information per element is plural bits or above by providing a circuit to control an injecting charge and set the threshold voltage of a memory element to an optional value and a circuit to read the threshold voltage or the changing quantity. CONSTITUTION:A drain voltage capable of injection of a hot electron through a transfer gate switch 9 is applied to an element 10 for injecting a hot carrier. In such condition, to the floating gate of a floating gate type MOSFET 10, a drain electric current conducted at a channel is accelerated at the high electric field area near the drain junction, comes to be the hot electron and is injected through a gate oxidization film. Thus, the I-V characteristic of a floating gate type MOSFET for memory, in which two floating gates are electrically connected, is shifted in parallel in the gate voltage shaft direction. By continuing the hot electron injection until the gate voltage of a gate terminal 15 comes to be the voltage equivalent to the information to be stored, the MOSFET having the threshold voltage equivalent to the information to be stored can be obtained.

Title: Image reader
Inventor: YOKOBORI JUN
IPC: H04N1/04
Filed: 1987-06-05
Abstract: PURPOSE:To decrease the quantity of data to supply a speed pattern and to reduce the size of the capacity of a memory by storing the basic pattern of a pulse string to be impressed to a pulse-controlled motor, and using the constant-speed pulse string of the basic pattern by charging its number of pulses in the case of executing a scanning whose scanning length is different from the basic pattern. CONSTITUTION:The speed data of a basic pattern to give a maximum scanning length is stored as a value in terms of pulse cycle. A CPU 32, when a stepping motor 10 enters the drive mode, resets an internal memory and an address counter, and reads a rise-end pulse PA and a maximum scanning length PM from the memory 33. The CPU 32 also obtains a scanning length PL in order to execute the read in according with original-size data and variable power data. In this case, the pulse counting is increased by D=PM-PL after the execution of a rise pulse part PA, hence the length of an equi-speed pulse part PB is decreased by D, thus the PB reduces to PB'. This PB' varies depending on the scanning length PL, therefore it can be easily obtained out of the basic pattern.

Title: Thin-film magnetic head
Inventor: MATSUURA TSUKASA
IPC: G11B5/31
Filed: 1992-06-03
Abstract: PURPOSE:To suppress the floating of a magnetic medium and to attain the good contact of magnetic cores and the magnetic medium by providing grooves for generating a negative pressure to at least one of the front, rear, left and right of the thin-film magnetic cores along the sliding direction of the magnetic medium. CONSTITUTION:The negative pressure grooves 8 are formed on the front and rear of the thin-film magnetic cores 2. The magnetic medium is floated by a dynamic pressure when the thin-film magnetic cores 2 move in a progressing direction A but the isothermal expansion of an air film arises in the parts of the negative pressure grooves 8 and, therefore, the pressure drops. The magnetic medium is attracted toward substrates 1 in the parts of the grooves 8 and the cores 2 and the magnetic medium come into contact in the nearly zero state of spacing. Then, the magnetic medium comes stably into contact with the cores 2. The high-density recording and high-output reproducing are thus executed.

Filed: 1989-06-05
Abstract: PURPOSE:To improve the control response and to ensure the stable and safe control for a controller applied to an instrumentation system by changing forcibly the integration control arithmetic output in accordance with the degree where a control signal exceeds the signal control value. CONSTITUTION:A difference signal MVn - 1 between the preceding input signal and the preceding output signal applied to a changing rate control means 21 is obtained by a difference signal acquiring means 22 and sent to an addition means 23. At the same time, an addition signal (P + D)n of the proportion control arithmetic output Pn and the differentiation control arithmetic output Dn is supplied to a changing component arithmetic means 20. The changing component DELTA(P + D)n between the preceding value and the current value of the means 20 is obtained and added to the signal DELTAMVn - 1. This addition signal is compared with the changing rate limit value which is previously judged by a changing rate variance judging means 24. If it is judged that the addition signal is kept out of the limit value of the changing rate, a switching means 16 is set in an inconductive state to stop the integration control arithmetic output and to hold the preceding integration control component. Thus store effect of the integration control component is eliminated and the overshoot can be prevented.
