Filed: 1990-05-18
Abstract: PURPOSE:To make it possible to detect the position of a mark with high accuracy by installing at least two types of signal detectors and adopting two different processing methods and selecting either of them as required. CONSTITUTION:Signal detection and signal processing methods are not confined to one type only when used. At least two types are provided. For example, as for a mark signal which reflects the geometrical offset of a substrate 105, at least two detectors 103 and 104 are provided.

Title: Zero detection circuit for frequency divider
Inventor: KAWAHARA HISASHI
IPC: G04G3/02
Filed: 1983-07-12
Abstract: PURPOSE:To improve the compactibility and designing property of an IC chip by taking out zero state as level signal with a simple circuit in a desired divider composed of a binary counter. CONSTITUTION:When 60sec detection signal PR is outputted, FFs 8a-8f are reset while being fed to the setting side input of a zero detection circuit 9 to turn a zero detection signal PZ to the ''H'' level. An FF7b lof a zero-returning switch circuit 7 is reset and a control signal PC of the ''H'' level is outputted from an inversion output terminal. A switching circuit 3 selects a 1Hz signal of a frequency dividing circuit 2 again and starts it by switching. The rising of the 1Hz signal is fed to a waveform shaping circuit 4 so that the zero detection signal PZ from the zero detection circuit 9 maintains the ''H'' level thereof until a motor driving signal PD is outputted. In other words, the zero detection signal PZ is outputted only while the contents of FFs 8a-8f of a detection circuit 8 change from ''0'' to ''1'' as the second hand moves to the position of 1sec from the zero position. Thus, the zero state of a divider can be taken out as a level signal with a simple circuit.

IPC: F16K13/10
Filed: 1989-05-20
Abstract: PURPOSE:To allow correct operation when a device is adapted to the low fluid pressure by inserting a pressure guide pipe downward into a liquid container storing a preset quantity of a liquid, and immersing it to the preset depth in the liquid. CONSTITUTION:When an air stream W generated by a fan 4 passes a fluid passage 1, a pressure difference is generated between the front and the rear of a heat exchanger T. This pressure difference is detected by a pressure difference meter 3 provided on a bypass passage 2. When the pressure difference between the front and the rear of the heat exchanger T is increased and nears the limit pressure of the pressure difference meter 3 due to the abnormal rotating speed of the fan 4, the pressure guided into the pressure guide pipe 7 of a pressure relief device A from the inlet side 2a of the passage 2 exceeds the head value of the liquid immersion section of the guide pipe 7, the water in the guide pipe 7 is discharged, and the guided pressure is released to the gas phase section of a liquid container 6 as bubbles B and guided to the outlet side 2b of the passage 2. The pressure exceeding the limit pressure is not applied to the pressure difference meter 3, and the device A functions satisfactorily as a safety device.

Inventor: MUROFUSHI TATSUYA
IPC: H03K17/10
Filed: 1995-04-27
Abstract: PURPOSE: To prevent unbalance of voltage to be applied to each transistor by saturating all of a plurality of transistors connected inseries when an excessive current flows due to the short circuit of a load. CONSTITUTION: A couple of IGBT 10, 14 of which current paths of the emitter and collector are connected in series is inserted into a current path of a load 20.
