IPC: C02F1/40
Filed: 1996-08-13
Abstract: PROBLEM TO BE SOLVED: To provide an oil/water separating system in which there is no oil leakage and discharge to the outside even if one oil/water separator fails. SOLUTION: To an oil/water separator 1 on the outlet side, a second oil/ water separator 2 is connected.

Title: Gas laser
Inventor: MURATA TAKAAKI
IPC: H01S3/03
Filed: 1988-09-19
Abstract: PURPOSE:To obtain a gas laser apparatus having a high efficiency and high reliability by a method wherein the surface of a metallic vessel in which laser medium gas is enclosed is tightly cladded with a metallic layer which is made of metal having a higher conductivity than the material of the vessel and has a thickness equivalent to a skin depth corresponding to the frequency of a high frequency source. CONSTITUTION:A metallic vessel 7 is made of material such as stainless steel which maintains mechanical strength even if it is applied to a welded structure. On the other hand, the surface of the metallic vessel 7 is tightly cladded with a cladding layer 13 made of metal such as copper or aluminum which has a higher conductivity than the material of the metallic vessel 7 by a means such as plating or flame-coating. That is, by selecting the metal which can maintain sufficient mechanical strength even if the welded structure is employed, the metallic vessel can withstand an external force produced by a large pressure difference between enclosed internal gas and the external air. As a high frequency current can be made to flow only in the skin depth part of the surface of the metal layer by a skin effect, if the high conductivity metal cladding layer having the thickness equivalent to the skin depth is applied to the surface of the metallic vessel, the high frequency current is made to flow in the high conductivity metal cladding layer, so that the loss of the high frequency current can be avoided.

Title: Constant-voltage circuit
Inventor: FUKUZAWA FUMIHARU
IPC: G05F3/26
Filed: 1984-11-05
Abstract: PURPOSE:To obtain a constant voltage which is not related to a threshold voltage and not affected by manufacturing variation, by forming a constant- voltage circuit by using two p channel FETs, three n channel FETs, and two resistances. CONSTITUTION:The constant-voltage circuit shown in the figure is constituted by using p channel and n channel insulating gate type FETsQ2 and Q3 and Q1, Q4, and Q5 and resistances R1 and R2. The output voltage of the constant- voltage circuit can be obtained from Formula I. The m1-m5 of the formula are constants expressed in the channel dimension ratio between the FETsQ1 and Q2, q is the charge quantity of electron, K is Boltzman's constant, and T is absolute temperature. That is to say, the output voltage depends on the relative ratio of the resistances and that of the channel dimension ratios of the FETs. Since the manufacturing accuracy of the m1-m6 can be maintained relatively easily and the relative ratio of the resistances can be maintained highly accurately, the output voltage becomes a constant voltage which is not related to a threshold voltage and not affected by the manufacturing variation.

Title: Electronic numbering apparatus
Inventor: SAKAKIBARA KAORU
IPC: B41K3/10
Filed: 1992-09-01
Abstract: PURPOSE:To achieve the stabilization of character selection regardless of the decrease in power supply voltage and the increase in load torque by providing a voltage detecting circuit; which monitors the voltage of a power supply circuit for supplying electricity all the time, and providing a speed control means for stepping motors based on the voltage fluctuation signal from the detecting circuit. CONSTITUTION:In a resetting step, the spring pressure of a type spring 11 for all digits is applied on a stepping motor 25 for directly driving a type wheel shaft 7. Load torque becomes twice the torque digit number at the ordinary character selecting operation. Therefore, the required driving torque is secured by decreasing the speed of the motor 25 from the normal speed with a reset-operation controlling means. The control is performed so that the secure operation is performed even in the resetting step. The torque is largely decreased at the constant speed by the decrease in voltage. Therefore, the voltages of a plurality of batteries 32 are monitored with a voltage detecting circuit 50 and a speed control means. When the voltages are decreased, the fact is transmitted into a CPU 38. The speed, at which the required torque is obtained, is judged with the CPU 38. The stepping motors 25 and 26 are controlled through drivers 40 and 41.

Monitor current detected when the mask 11 is put on the flag 7 forms pulses 13 corresponding to the slits 12. Since the pulses 13 have the respective heights proportional to ion density at the position of the slits 12, the heights is proportional to ion implantation density at the projection position of the slits 12 on a board S when the mask 11 is parallel to the board S, to show Y-direction distribution of the ion implantation density on the board S.
