Patent JP-S58105628-A (JP)
Title: Interface circuit
Inventor: MAMETA JIYUNICHI
IPC: H03K19/018
Filed: 1981-12-18
Abstract: PURPOSE:To precisely execute switching operation by a transistor (TR) independently of the existence of leak current by composing a switching means of a current mirror circuit. CONSTITUTION:If leak current (ie) does not flow in an interface circuit IC, a transistor (TR) Q1 is turned on/off in accordance with the pulse signal level of a pulse signal generator 2. If a pulse signal is in a low level when current (ie) flows, the current (ie) flows into a current mirror circuit consisting of the TRQ1 and a diode D3. Current flowing between the collector and emitter of the TRQ1 is almost the same capacity as the current (ie). Therefore voltage drop due to a resistor R1 is sufficiently low and the TRQ1 is regarded to be in an off status.  When the input signal is turned to the H level, current I0+ie (where I0 is the  current flowing into a constant current circuit 1) flows into the current mirror  circuit. However the current I0 is set up sufficiently larger than the current (ie),  so that the malfunction of the TRQ1 is prevented independently of the existence  of the current (ie) and breaking strength also is not reduced.

Abstract: PURPOSE: To separate a coal tar distillate into various fractions by increasing the polarity of a developer.  
     CONSTITUTION: A coal tar distillate (e.g. esp. a distillate fractionated at 260°C contains various nitron-contg. heterocyclic compds.) is mixed with 10-50 vol.% (based on the distillate) nonpolar solvent (e.g. cyclohexane), then developed with a separation column with a stationary phase formed thereon (e.g. silica gel or neutral alumina having a particle size of 60-200 μm), and is developed with the nonpolar solvent to elute nonpolar arom. hydrocarbons from the fraction. A polar solvent remains at an adsorption phase. Then, the fraction is eluted with a single, more polar developer or with a plurality of developers with polarities gradually increased. Pref. examples of a polar solvent used together with the nonpolar developer are propyl acetate and ethyl acetate. The mixing ratio of the nonpolar solvent to the polar solvent is (9:1)-(0:1). The elution is conducted at 20-50°C.

Abstract: PURPOSE:To prevent a card from being stolen during use by emitting an alarm such as flickering of a lamp or the sounding of a buzzer when the pulling-out of an inserted card is detected. CONSTITUTION:When a memory card 3 is inserted in the card slot 4 of a laser printer main body 1, a card connector 16 is connected to the male connector of the memory card 3. As a result, a DET terminal being a card detection terminal is earthed to become a low level and a high level DET signal (showing the presence of the card) inverted by a NOT circuit 15 is transmitted to I/O 14. When the memory card 3 is pulled out, since the DET terminal of the card connector 16 is opened, the input of the NOT circuit 15 becomes a high level and a low level DET signal (showing the absence of the card) obtained by the inversion of the high level is transmitted to the I/O 14. This signal showing the pulling-out of the memory card is read by a CPU 10 to achieve the functions of the detection of the pulling-out of the card and the alarm of the pulling-out thereof.
