Title: Control circuit of mass flow controller
Inventor: SHIMOE OSAMU
IPC: C23C16/455
Filed: 1990-01-08
Abstract: PURPOSE:To exactly measure the mass flow rate of gas by constituting the circuit so that a correcting circuit added to a sensor circuit converts a detecting signal from the sensor circuit to an exact mass flow rate corresponding value, based on a signal from a temperature sensor for detecting a gas temperature. CONSTITUTION:A correcting circuit 4 is constituted so that since specific heat is varied by the kind of gas allowed to flow to a gas supply conduit 1, a detection value from a sensor circuit 2 can be converted and set so as to show an exact mass flow rate in accordance with specific heat of every kind of gas. That is, in accordance with the kind of gas, the correcting circuit 4 is set in advance, and when gas is allowed to flow to the gas supply conduit 1, a temperature sensor detects a gas temperature and inputs it to the correcting circuit 4. Based on the gas temperature, the correcting circuit 4 converts the detection value from the sensor circuit 2 to a detection value corresponding to a correct mass flow rate by specific heat corresponding thereto. In such a way, even in the case a temperature of gas allowed to flow to the gas supply conduit is different, and even if the kind of gas is varied, the mass flow rate of gas is detected exactly and the control valve can be controlled with high accuracy.

Filed: 1988-01-08
Abstract: PURPOSE:To adjust the retreat position of a magnetic head at the optimum position by providing a means adjustable for the stroke of a power transmission member from a driving source for head elevation to a magnetic head table. CONSTITUTION:By energizing a spindle motor for rotating a magnetic disk and monitoring the load current of the motor as turning a retreat quantity adjusting screw 29 gradually, at the beginning, a large load current flows because the magnetic head 7 is pressurized contact with the magnetic disk, however, the load current due to the contact of the magnetic head 7 with a sheet goes to zero at a position where the adjusting screw 29 is located at a certain position. At this time, it can be assumed that the retreat position of the magnetic head 7 decided by the position of the adjusting screw 29 is the most ideal retreat position nearest to the magnetic disk. In such a way, it is possible to adjust the retreat position of the magnetic head 7 at the optimum position.

Title: Water measuring instrument
Inventor: ADACHI TORU
IPC: G01N1/00
Filed: 1993-01-08
Abstract: PURPOSE:To prevent contaminate deposited inside a water-supply pipe from flowing to a water measuring instrument by providing a switching valve for switching the flow of a sample water to a water-sampling path and to a branched forced drain path. CONSTITUTION:When a sample water is measured. a first electric valve 7 is opened by a control device 6 and a second electric valve 10 is closed. In this state, the sample water flowing through a main pipe 2 flows to a detection part 4 via a water-supply pipe 3, a water-sampling path 5, and the valve 7 and then is delivered from a drain pipe 8 after the water is measured. In this manner, contaminate stays at the water-supply pipe 3 after measurement for a long time. At the time of washing, the valves 7 and 10 are closed by the control device 6 and supply of water to the detection part 4 is broken. After that, the valve 10 is opened while the valve is closed and then the sample water is supplied to a forced drain path 9. The flow rate of the path 9 is much larger than that of the path 5. Therefore, the flow rate of the sample water flowing; through the water-supply ductwork 3 increases and the deposited contaminate is pushed away through the path 9 due to the force of the sample water.

Title: Laser light absorbing device
Inventor: YAMADA KIMIO
IPC: G02B5/00
Filed: 1984-01-11
Abstract: PURPOSE:To prevent a local temperature rise, and to prevent a damage of an absorbing plate by constituting the titled device so that a coefficient of linear absorption of the absorbing plate increases toward an emitting side from an incident side, and an energy absorption rate in the absorbing plate becomes uniform. CONSTITUTION:This device is constituted of a laser light 1 polarized in parallel to an incident surface, an auxiliary absorbing plate 6 consisting of a color glass filter whose transmittivity is <=1/10<6>%, and an absorbing plate 7. Until the incident light is attenuated to 1%, a coefficient of linear absorption is increased in accordance with lambda=lambda0/(1- lambda0X) (in the expression, lambda, lambda0 and X denote a coefficient of linear absorption, a coefficient of linear absorption of an incident end, and a distance separated from the incident end, respectively), and thereafter, it is kept constant. In case when an incident energy of the laser light is 10J, when a path length in the absorbing plate is 0.99/lambda0, its energy is attenuated to 0.1J. A range for increasing the coefficient of linear absorption is changed by an intensity of the incident light. As for the laser light which has been made incident at a Brewster's angle with a normal of the plate 7, the whole energy is absorbed in the plate 7. The reflected light generated by a fact that the laser light is not a complete parallel is absorbed by the auxiliary absorbing plate 6.
