Title: Temperature sensor
Inventor: KITSUKAWA KANEHISA
IPC: G01K7/20
Filed: 1992-07-13
Abstract: PURPOSE:To prevent deterioration due to migration and at the same time obtain a temperature sensor with a high detection accuracy inexpensively by using a CR oscillation circuit as a detection circuit and then using a temperature- measuring resistor for one part of the feedback resistor at the feedback part of the circuit. CONSTITUTION:A temperature-measuring resistor 4 is applied as a feedback resistor of a Wien bridge type oscillation circuit. A Wien bridge is constituted by the resistor 4 with feedback resistors R0-R3 and a resistance Rs, the output is connected to an amplifier 10, and further the output is positively fed back to the Wien bridge. Since an oscillation frequency fluctuates due to the change in the resistance Rs of the resistor 4, temperature can be detected by detecting the frequency. Since the resistor 4 is used as a feedback resistor for the oscillation circuit, AC is applied, thus preventing deterioration due to migration even in a temperature-sensitive element which is constituted of a ceramic substrate and the resistor 4.

Abstract: PURPOSE: To attain efficient new broadcast station followup (NF) processing by applying the NF processing only to stations whose reception time is new in a reception history list. CONSTITUTION: A system controller 10 provides a command to a PLL circuit 2b so as to allow the circuit 2b to receive a station frequency signal fj depending on frequency data in an i-th (i:1 is set at first) address in a memory area for reception history corresponding to a network in a memory 11 corresponding to the channel selection by an operation section 12. When it is discriminated that a reception electric field strength obtained from a level detector 7 exceeds a setting level in the reception state of the station frequency fj, because it means successful reception, the reception of the received frequency signal in this case is continued. Then the memory content is shifted one by one address to store a newest reception frequency fj and a time series reception history list is formed for each network.  When the received electric field strength is less than the setting level, a current variable (i) is incremented by one and then the processing is repeated.

IPC: E21D11/08
Filed: 1993-08-25
Abstract: PURPOSE:To correct an irregularity on a connecting face, bring it into face contact, and disperse stress by applying a hardening inhibitor or a foaming agent to a formwork facing the connection face of a large segment, and forming a low-compressive strength thin layer on the surface of a product. CONSTITUTION:When a concrete segment used for a large-cross section shield tunnel or the like is to be manufactured, a concrete hardening inhibitor or a concrete foaming agent is applied in a liquid form to a formwork forming the connecting face of the segment. Concrete is filled and hardened in the formwork. The progress of hardening is delayed or foaming is applied on only the connecting face to form a low-compressive strength concrete thin film. Even when an irregularity is generated on the connecting face by the manufacturing error of the segment or a temperature change, the low-compressive strength concrete thin layer is collapsed by stress concentration to correct the irregularity, and the whole connecting face is brought into face contact. The size error is absorbed, and a water leak can be prevented.

Filed: 1988-08-24
Abstract: PURPOSE:To make possible the recording of data at high speed and density by employing exposure devices with exposure points staggered in a main scan and subscan directions and performing an exposure at each recording position at different timing within a single scanning operation. CONSTITUTION:An LED array 1 consists of four light-emitting diodes (LED) 3 arranged, as a recording light source, at an interval S in the main scan direction of the photosensitive surface. The length of each main scan direction equals the interval S. The LEDs 3 constitutes an exposure device with a slit or a lens which condenses the light to the photosensitive surface 2. The photosensitive surface 2 is realized as a photosensitive element drum which rotates in the main scan direction. To record a single image, the photosensitive surface 2 is scanned only once, and its main scanning operation is performed by moving the photosensitive surface 2 in the main scan direction. The subscanning operation is achieved by moving the LED array 1 in the subscan direction. The condensing point of the light from each LED 3, that is, the exposure point of each exposure device is located at a position deviated by an interval A on the same main scanning line. This interval S corresponds to an image interval (interval between recording positions) on each scanning line.
