Filed: 1996-03-13
Abstract: PURPOSE: To improve the work efficiency at the time of being judged that processing liquid will run out, and prevent the occurrence of defective lot. CONSTITUTION: Residual quantity sensors 115a-115c detect the residual quantity of the processing liquid from the weight of a processing liquid reservoir, and this outputs an on signal when it comes to a specified value or under, and outputs an off signal in case that it does not fall under a specified value or under. The specified value of the residual quantity of processing liquid is made the sufficient quantity capable of processing all the substrates being sent already from a substrate transfer unit 2 to the heat processors 33-35, etc., of a process treatment unit 3. The main controller issues an alarm when an on signal is detected from the residual quantity sensor, but at that time, it stops the sending out of the substrate transfer unit, and it continues the operation of the heat treatment equipment as it is.  At the point of time when all the processing of the substrate being already sent to the heat treatment equipment is finished, the device is stopped. Therefore, there never occurs such trouble that a substrate during treatment is produced.

Title: Seam detecting device for magnetic material belt bar
Inventor: UEHARA TSUKASA
IPC: G01B7/00
Filed: 1988-04-07
Abstract: PURPOSE:To prevent a seam from being misdetected owing to whether the width of a lead frame is wide or narrow by inputting the difference voltage between the output of an oscillator and a reference voltage to a differential amplifier and making a self-adjustment of the effective area value of said amplifier by utilizing the level of the output of a detector based upon whether the lead frame width is wide or narrow. CONSTITUTION:The output of the oscillator 10 is inputted to the amplifier 21 through a differentiating circuit 18, so its output E2 is 0 in a stationary state. When A1 and A2 are constants, an output E0 is E0=(E2-E1)A2=-E1A2 and E1=(VREF-VS)A1. Therefore, EOSA=-(VREF-VSA)A1A2 EOSB =-(VREF-VSA)A1A2, where EOSB and EOSA are the outputs of the differential amplifier 16 corresponding to a wide and a narrow lead frame. When the effective area value voltage of the differential amplifier 22 is denoted as VTHe, VTHeA (VTHeB)=VTH-EOSA(EOSB), so the self-adjustment of the area value is made according to whether the width of the lead frame is wide or narrow. Here, when the seam passes an oscillation coil 11, that is detected by the circuit 18 and a switching element 23 operates.

Abstract: PURPOSE:To accurately measure a wt. by perfectly preventing the invasion of a liquid into a housing by hermetically sealing the gap between the hole of the housing and a sensing part by an expansible body and providing a vent hole to the housing at a part other than the hole of the housing. CONSTITUTION:The gap between the hole 70c of a housing and a sensing part is hermetically sealed with an expansible body and a vent hole 13 allowing air to flow so as not to eliminate the pressure difference between the open air and the interior of the housing due to the expansion and contraction of the expansible body 84 is provided to the housing at a part other than the hole 70c of the housing. That is, since the gap between the hole 70c provided to the upper part of the housing and each of supports 80 - 83 is hermetically sealed by the expansible body 84, no liquid penetrates into the housing from the gap. The air in the housing expands and contracts by the temp. change in the housing but, since the housing communicates with the outside by the vent hole 13, internal pressure does not change. Since the expansible body 84 does not expand and contract by the change of the internal temp. of the housing, no effect is exerted on the sensing part to which the expansible body 84 is fixed and, as a result, no effect is exerted on a weighed value. By this constitution, the invation of a liquid into the housing is perfectly prevented and an accurate wt. can be measured.
