Title: Pyroelectric detector
Inventor: FUKUDA KATSUYOSHI
IPC: G01J5/02
Filed: 1979-07-27
Abstract: PURPOSE:To improve S/N by making it easy to handle a pyroelectric detector by making its constitution miniature and lightweight, by forming an electrooptical element, used as the method of varying periodically a dose of radiation rays such as infrared rays, in the same body with a pyroelectric element. CONSTITUTION:An electrooptical element, constituted by sandwiching liquid- crystal plate 18, whose light polarization surface turns when an electric field is applied, between polarizing plates 191 and 192 crossing at righ angles, is formed in the same body with pyroelectric element 11. In this constitution, applying a repetitive pulse voltage between pins 163 and 164 incident radiation rays are interupted by polarizing plates 191 and 192 while liquid-crystal plate 18 is not applied with any electric field and rotates the polarization surface while the electric field is applied to liquid-crystal plate 18, so that at least some of incident radiation rays will strike pyroelectric element 11 by penetrating polarizing plates 191 and 192. Namely, radiation rays incident to pyroelectric element 11 are periodically intermitted, and consequently a pyroelectric output can be obtained between pins 161 and 162, so that the incident radiation rays can be detected. Thus, the unit is made miniature and lightweight and its handling can be facilitated.

Title: Thermal recording paper
Inventor: SENBA KATSUMI

Filed: 1988-04-18
Abstract: PURPOSE:To enable detection of a paper other than a designated one and prevent paper jamming or breakage of a thermal head from occurring, by providing a color forming layer of a thermal recording paper with a specified printing part and an effective printing part which are capable of forming different colors. CONSTITUTION:A thermal recording paper comprises an upper layer of a surface coating material 1, a color forming layer 2 as a black color forming intermediate layer, a lower layer of a base material and coating material 3, and a color forming layer 4 capable of forming a color (e.g., green) different form that of the color forming layer 2, the layer 4 being provided at the leading end of the recording paper and having a length of about 5cm. When heat is supplied from a thermal head to the thermal recording paper, for example, the green color forming layer 4 is caused to exude through the surface coating material 1 to form the green color. This color is detected by a reflection-type photosensor having a sensitivity varied depending on wavelength or other similar means, thereby checking whether the recording paper is a designated one. When the recording paper is not the designated one, energization of the thermal head is so controlled as to inhibit the subsequent printing. When the recording paper is the designated one, the thermal head is so controlled that the subsequent black color forming layer 2 will be effective for printing.

Title: Temperature compensation circuit for magnetic encoder
Inventor: SEKIGUCHI TOKIO
IPC: G01D5/18
Filed: 1988-04-21
Abstract: PURPOSE:To always obtain output voltages of a constant amplitude even when the temperature changes by providing an adder, square root extracting operator, comparator, etc. CONSTITUTION:The output voltages of sensors 4-A and 4-B at temperature t1 are respectively set at Ea1 and Eb1 and, when the temperature rises, a resistance R increases since the resistance temperature coefficient is positive and, when the output voltages drop, outputs of operational amplifiers 11 and 12 decline. In addition, outputs of adders 25 and 26 also decline and the output voltage of a square root extracting operator 27 drops. Therefore, the output of a comparator 28 increases and the input of a current controller 30 increases. As a result, currents of the sensors 4-A and 4-B are increased and, accordingly, the output voltages of the sensors are increased. Thus the input voltage of the comparator 28 is controlled so that the input voltage can be balanced with a reference voltage. Moreover, the output voltages of the sensors 4-A and 4-B are controlled so that the output voltages appearing at terminals 13 and 14 can have a constant amplitude irrespectively of temperature. When the temperature drops, rises in the output voltages are suppressed so that the output voltages can have the constant amplitude.

Abstract: PURPOSE:To make a refreshing terminal unnecessary and to package a dynamic RAM on a 24-pin package by activating an oscillator circuit by the combination of specific signals. CONSTITUTION:When an I/O5 is controlled by a control signal generator circuit 10 and an output enable signal is supplied to a terminal D, an output of a sensor amplifier 4 is outputted through a terminal F.

On the other hand, a chip enable signal, the output enable signal and the write enable signal are supplied to a terminal C, the terminal D and the terminal F, respectively, which causes the I/O5 to be unactivated. Simultaneously a refreshing clock oscillator circuit 9 is activated due to a high level output from an AND gate 12, and a memory cell array 1 of dynamic RAMs is refreshed. Thus a refreshing terminal for activating the circuit 9 is made unnecessary, and the dynamic RAM can be packaged on a 24-pin package accordingly.

Abstract: PURPOSE: To reduce the production cost of a graded function material by rotating a heat resistant vessel under control of its rotating speed and forcibly cooling its outer periphery and both end faces to solidify a content material while allowing its compsn. to change in a radial direction. CONSTITUTION: A coil 9 is placed between a rotary drum 1 and the heat resistant vessel and AC electric power is supplied thereto. Iron cores 91, 92, 93 are formed by superposing magnetically permeable steel sheets on each other in order to adequately guide the magnetic fluxes generated by this coil 9. While the iron cores 91, 92 are formed to a simple doughnut shape, the iron core 93 has holes to allow the passage of cooling liquid and steam so that eddy currents are uniformly generated in the material to be heated. The cooling liquid is injected from an injecting path 6 to immerse the lower half of the heat resistant vessel 1 for the purpose of cooling the molten material.  The cooling liquid existing in the lower half of the rotary drum is sprinkled to the heat resistant vessel 1 from the space of the upper half by a pumping up water spraying wheel 71, 72 in contact with the bottom side and cap side of the heat resistant vessel 1 to forcibly cool the vessel. As a result, the graded function material continuously changed in the compsn. in the radial direction is produced.
