Title: Image formation device
Inventor: NIKI YUJI
IPC: G03G21/00
Filed: 1991-04-11
Abstract: PURPOSE:To avoid the deterioration and useless consumption of toner, provide image stable even with the elapse of time, and reduce running cost by separating a belt photo-sensitive body from a development means, when image is not formed. CONSTITUTION:A photo-sensitive belt 2 is provided with a separation member 48. A pressure roller 50 is made of such material as not adversely influences the belt 2, even when in contact therewith. The pressure roller 50 is laid at the downstream side of a development position where a development roller 18 is in contact with the belt 3 in the travel direction thereof. Furthermore, a separation mechanism presses and deforms the belt 2 in an F direction, thereby separating the belt 2 from the development roller 18. Namely, the separation member 48 oscillates in a G direction at an ordinary development process. As a result, the member 48 is separated from the belt 2, and consequently the belt 2 is reset to be in slidable contact with the development roller 18 for performing a development process. As aforementioned, the separation member 48 oscillates about an oscillation support point, and presses and deforms the pressure roller 50 pivotally supported on an arm 54, thereby separating the belt 2, when no development process takes place.

Title: Heat-conductive radiation pixel detector
Inventor: NAKAGAWA HIROSHI
IPC: G01T1/24
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To detect high-energy radiation without changing characteristics for a long time by reading a signal using a superconductive quantum interference element being provided on the same substrate. SOLUTION: A block A is a room-temperature-system high-voltage power supply with a power supply +HV, an internal resistor R, and an internal capacitor C and supplies a high-voltage bias to a semiconductor substrate with an internal resistor Rs and an internal capacitor Cs of a block to be installed in an extremely low-temperature environment. Also, a block C indicates a superconductive quantum interference device(SQUID) and an ion current pulse is transferred to input coils L1 and L1' that are magnetically coupled to superconductive loops L2 and L2' of the SQUID. An AC bias current required for operating the SQUID is injected from the indoor-temperature-system power supply to the connection point between the superconductive inductors L2 and L2'.  When a current pulse is generated from a block B in this state, a current pulse is injected to a quantum interference loop including L2, L2', J1, and J2 via L1 and L1' to switch J1 and J2, thus generating an output current in an output resistor Rload and increasing the input sensitivity of the SQUID.

Abstract: PURPOSE:To obtain a measured value of high accuracy even in the case a fluctuation is large due to individual difference of photoelectric pulse wave amplitude and a state of the body by approximating a photoelectric pulse wave by a tertiary correlation curve, and setting an average value of the photoelectric pulse wave at the maximum point derived from this correlation curve as a control target value. CONSTITUTION:In a pressure ascending process of a cuff 1, a photoelectric pulse wave signal for showing a capacity fluctuation which follows a blood pressure pulsative variation of a finger of a person to be examined is detected by a pressure sensor 7, and an amplitude value of every prescribed time or every one pulse and an average value of that time are stored in a memory of a control CPU circuit 15 through an A/D converter 13. After these data are taken completely, pressure is reduced gradually by operating a pressure supply means 5 and a solenoid valve 3. Thereafter, based on a data group stored in the memory of the control CPU circuit 15, a tertiary correlation curve being approximate to a photoelectric pulse wave is calculated, an average value of the photoelectric pulse wave is derived from the maximum point of this correlation curve, and this value is set as a control target value. Subsequently, pressure applied to a finger is controlled by the pressure supply means 5 and the solenoid valve 3 so that an output signal of a photodetecting means 21 becomes this control target value, and a pressure waveform of this time is read as a blood pressure waveform of a person to be examined.

Abstract: PURPOSE:To remove dangerous possibilities to start feeding of a paper while it is set abnormally by providing a sensor for detecting switching of a clutch means, and rotating a feed motor in a forward and a reverse directions when said sensor detects switching. CONSTITUTION:When a lever 20 is driven in a direction of an arrow B, a slide gear 15 is detached from a tractor gear 14 by the resilient force of a coil string 19. At this time, a switch 21 is changed from the disconnecting state to the connecting state, and a detecting means detects this change. Accordingly, a feed motor 7 is rotated 30 steps alternately in a forward and a reverse directions before printing is started again. Therefore, even if the slide gear 15 is not able to slide due to some reason, e.g. friction force, and coupled both to a friction gear 12 and to the tractor gear 14, it is allowed to slide during the forward-and-reverse rotation of the feed motor, and accordingly turned into the normal state detached from the tractor gear 14. A continuous paper 2 is never fed during the subsequent transfer.

Filed: 1988-04-01
Abstract: PURPOSE:To implement low noises, to facilitate forming a telemetry system and to obtain a body embedded type pressure sensor, by forming a unitary body of a signal processing circuit and the pressure sensor, and employing a two-wire output system. CONSTITUTION:A diaphragm 2 is formed in a silicon substrate 1 by a micromachining process. A signal processing circuit 3 is integrated on the substrate 1. Then an electrode pattern is formed on a glass substrate 4. Position alignment is performed, and the substrate 4 is bonded to the silicon substrate 1 by an anode bonding method. Thus, the electrode pattern of the glass substrate 4 is bonded to an N<+> layer which is diffused on the silicon substrate and connected to the circuit 3. Then, two-wire type output lines 5 which are commonly used for power supply and signal lines are connected to the circuit 3. The output lines 5 are fixed with a bonding agent 6. In this constitution, a capacitance sensor and a detecting circuit are arranged in the close proximity. Therefore, mixing of noises from the outside is less. A compact pressure sensor which can be embedded in a body and which is characterized by small power consumption is obtained.
