Abstract: PURPOSE:To set a passing band gain and a cutoff frequency easily by using an inverting amplifier circuit including an operational amplifier, and a variable differentiating  circuit including an operational amplifier and a variable gain amplifier. CONSTITUTION:The inverting amplifier circuit 40 consists of the operational amplifier  27 and resistances 29 and 30, one terminal of the resisitance 29 is used as an input  signal terminal while the connection point between the output terminal of the operational amplifier 27 and the resistance 30 is used as an output signal terminal; and the  gain depends upon the ratio of the value of the resistance 30 and the value of the resistance 29. The variable differentiating circuit 41 consists of a varaible gain amplifier VCA 32, operational amplifier 37, and capacitor 31 and resistance 35 (which are a resistance and a capacitor reversely in a figure); the side of the capacitor 35 where the  1st output terminal 28 is connected is used as an input signal terminal and the connection point between the output terminal of the operational amplifier 37 and the resistance 35 is used as an output signal terminal. An input current is supplied to one of the 1st to the 3rd input terminals 25, 34, and 39 and an output voltage is led out to the 1st or the 2nd output terminal 28 or 36, thus obtaining various transfer characteristics.

Abstract: PURPOSE:To uniformize the thickness of a resist coated film by providing a coating liquid temp. controller and a detecting means for temp. to be control led and controlling the temp. so as to maintain a specified temp. difference. CONSTITUTION:Application of a resist on a semiconductor water 1 is executed by rotating a spin chuck 10 at a prescribed revolving speed. The resist liquid supplied by a resist piping 12 in this state is dropped from nearly the central position of the wafer 1 via a coating nozzle 14 and is uniformly applied over the entire surface of the wafer 1 by the centrifugal force generated as the chuck 10 rotates. The temp. controller 20 controls the heating temp. of a thermomodule 30 at one end of a temp. control water circulator 24 and supplies the water via the circulator 24 to a heat exchanger 22. A heat exchange is executed between this temp. control water and the resist liquid in the piping 12, by which the temp. of the resist liquid is controlled. The evaporation rate is kept constant in this way and the thickness of the coated film is uniformized.

Title: Setting releasing system of access time
Inventor: JIHIKI MASAYUKI
IPC: H04Q3/58
Filed: 1981-01-30
Abstract: PURPOSE:To simplify the releasing operation as well as to reduce the load of an extension subscriber, by carrying out a calling detection within a prescribed time before a morning call and releasing the setting of an access time. CONSTITUTION:In case an access time is set to an address within a memory MCM corresponding to an extension subscriber SUB, a central controller CC compares a timepiece device with each time in the memory MCM. When a coincidence is obtained between them, a calling trunk RGT is connected to the subscriber SUB by a link LK of a switch frame SW via a switch controller SWC to call out the subscriber SUB. If the controller CC detects the calling of the SUB prior to the above-mentioned connection, the access time in the MCM and corresponding to theSUB is read. The corrsponding contents of the MCM are erased when the difference between the access time and the device TM, and thus the  set call of the access time is automatically released.
