Title: Developing method
Inventor: SUMI KAZUHIKO
IPC: G03F7/30
Filed: 1990-03-13
Abstract: PURPOSE:To make improvement in the uniformity of the temp. within a substrate to be processed and the removability of the foreign matter on the substrate prior to development processing by exposing the substrate to an org. solvent of low developability while rotating the substrate to be processed as a preprocessing stage for a developing stage. CONSTITUTION:Before the substrate is exposed to a developing soln., the substrate is kept rotated and is exposed to the soln. of the low developability. The nonuniformity of the developability by the temp. difference between the center and periphery of the substrate during the development generated when the substrate is exposed to the developing soln. is, therefore, uniformized by utilizing the evaporation heat by the org. solvent having the small developability. As to the removal of the foreign matter, the foreign matter is removed by the centrifugal force generated when the substrate is rotated and the force generated when the soln. comes into contact with the foreign matter. The improvement in the uniformity of the temp. within the substrate to be processed and the removability of the foreign matter on the substrate prior to the development processing is made in this way.

Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To perform a reliable stopper operation by disposing a stopper section of a installation member on the opposite side across a shaft section from a part of a knob projecting from a case and constructing a rotation stopper for the knob with an engagement section and the stopper section. SOLUTION: A knob 6 is installed so that a part of it may be projecting from a case 9. A stopper section 1b of an installation member 1 is disposed on the opposite side across a shaft section 1a from a part of the knob 6 which is projecting from the case 9. An engagement section 6c and the stopper section 1b constitute a rotation stopper for the knob 6. When the knob 6 is rotated to adjust the resistance, the handle is rotated with the force applied in the direction shown by an arrow A and therefore the handle 6 bends in the direction A with the shaft section 1a as a fulcrum. Even in this case, the rotation stopper constituted of the engagement section 6c and the stopper section 1b works with reliability. The thickness of the knob 6 is set between about 0.5 mm and about 2.0 mm. Due to this structure, the knob can have enough strength and a reliable stopper operation can be achieved.

Title: Break-in circuit for telegraph
Inventor: HIROHATA ATSUSHI
IPC: H04L15/04
Filed: 1995-03-20
Abstract: PURPOSE: To provide a break-in circuit for telepgraph which is capable of automatically changing the setting of the time constant of the switch from a transmission state to a reception state according to the transmission rate of a telegraph code. CONSTITUTION: An electrolytic capacitor C2 and resistor R3 and R4 generates the first signal obtained by detecting the signal of the telegraph code by a keying and discharging electricity by a prescribed time constant. A one-shot multivibrator 10 responds to the signal of the telegraph code and generates a signal. The integration by the electrolytic capacitor C3 is performed for the signal and the second signal corresponding to the transmission speed of the telegraph code of the keying is generated. A comapator 12 switches a radio equipment to its transmission state when the level of a first signal is more than the level of a second signal and switches the radio equipment to its reception state when the level of the first signal is less than the level of the second level.  Thus, the time constant of the switch from the transmission state of the radio equipment to the reception state is automatically set to be shorter as transmission speed is increased.

Title: Complementary output logical circuit
Inventor: HAGA MITSURU
IPC: H03K19/082
Filed: 1983-04-08
Abstract: PURPOSE:To attain simplification in terms of circuit by deciding on the base current of a PNP output transistor (TR) without using any resistance element. CONSTITUTION:When an input terminal 33 is at the GND level, a TRQ31 is off and no base current, therefore, flows through a TRQ34, which turns off. A TRQ 32 turns off because its base is connected to the TRQ31 and turns on since the amount I3 of the current of a current source 36 corresponds to the base power source of a TRQ33. Assuming that the hfe of the TRQ33 is betaN3, the TRQ33 is saturated and the amplitude level is sufficient when a load current is much smaller than I3XbetaN3. When an input terminal 33 is in an open state, the TRQ34 is held at the saturation potential and a sufficient-amplitude voltage is obtained as far as I2XbetaP> load current, where betaP is the hfe of the TRQ34.
