Title: Paper sheet feeder
Inventor: IWASHITA YOSHIHARU
IPC: G06Q50/10
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To facilitate maintenance and inspection work, etc., by constructing a feed frame cover from a lower cover secured to the lower portion of a feed frame, an upper cover freely attached to and removed from the end of the upper wall of the feed frame via an engaging part, and an opening member allowing the upper cover to be freely opened and closed. SOLUTION: A feed frame cover 3 comprises a lower cover 30 secured to the lower portion of a feed frame 2, an upper cover 33 freely attached to and removed from the end of the upper wall 2a of the feed frame 2 via an engaging part 32 that utilizes elasticity, and an opening member 34 allowing the upper cover 33 to be freely opened and closed. A lower guide member 8a fabricated separately is provided on the interior wall of the lower cover 30. Thus even if a bill S is jammed, for example, it can be prevented from springing out and dropping even with the upper cover 33 open since it is guided by the lower guide member 8a and a guide member 7. Maintenance and inspection work, adjustments, etc., are therefore made very easy, resulting in enhanced operability.

IPC: H01L21/324
Filed: 1985-08-30
Abstract: PURPOSE:To prevent a coarse substrate surface and outward diffusion of impurities, and to suppress occurrence of lamination defects, by forming an oxide film for preventing the coarse substrate surface on it, at a wafer temperature in an oxidizing atmosphere with little growth of lamination defects, and then by switching the process atmosphere into nonoxidizing atmosphere and further raising the temperature. CONSTITUTION:After a wafer is introduced into a heat treatment furnace, the furnace temperature is raised from 850 deg.C at a rate of 10 deg.C/min. For about 15min till the wafer temperature reaches an intermediate temperature 1,000 deg.C lower than a predetermined temperature 1,200 deg.C, the wafer is heat-treated in oxidizing atmosphere (dry oxygen). Next, at the same time when the wafer temperature reaches the intermediate temperature 1,000 deg.C, the heat treatment atmosphere is switched from the oxidizing atmosphere into nonoxidizing atmosphere (nitrogen). Next, the wafer temperature is raised and is kept at the predetermined temperature 1,200 deg.C for 15hr after reaching the predetermined temperature. Thereafter, it is lowered to 850 deg.C and then the wafer is taken out of the furnace.

Title: Pressure detecting device
Inventor: MIYATA TOSHIMASA
IPC: G01L1/22
Filed: 1985-08-30
Abstract: PURPOSE:To vary a reference voltage supplied to an A/D converter at the same ratio with the voltage of a power supply which is supplied to a pressure sensor and to eliminate errors in detection due to variance among parts by connecting a circuit for reference voltage generation to the power source which applies the voltage to the pressure sensor. CONSTITUTION:The output of a pressure detection part 1 which is affected directly by variation in source voltage has its amplification factor determined 5 and is amplified 3 and inputted to an A/D converter 12. The source voltage of the reference voltage generating circuit 8 to the A/D converter 12 is the same with a pressure detecting and amplifying part 10, so it is affected directly by the variation in source voltage as well. Consequently, the output of the A/D converter 12 is held constant regardless of the variation in source voltage. Its output is passed through a microcomputer 9 to supply various control signals to a load side. This constitution reduces errors due to variance among parts to obtain such a detecting device that the input of a pressure detection block corresponds to the A/D conversion output, one to one, at any time.

IPC: H05B33/12
Filed: 1993-07-30
Abstract: PURPOSE:To stabilize the light emitting properties in a short time without raising light emitting threshold voltage, and besides, improve the mass production and long-term reliability by setting the order of performing oxidation treatment and heat treatment, the condition, etc., optimally. CONSTITUTION:For the light emitting layer made in a substrate, the surface is oxidized in oxygen atmosphere or atmoshere including oxygen, and then heat treatment is performed for the light emitting layer in substrate temperature range of 400-500 deg.C. Moreover, in oxidation processing, in case that, for example, Zns is used as the light emitting layer, the composition rate of the light emitting layer is corrected by O atoms filling up the S defect on the surface of the light emitting layer, so the time required for the stabilization of light emitting properties is shortened. That is, the light emitting threshold voltage is lowered without marring the shortening effect of the initial aging time by oxidizing by setting the substrate temperature in heat treatment in the range of 400-500 deg.C, as result the mass producibility of a film EL element and the long-term reliability can be improved, and also the drive voltage can be reduced.

Abstract: PROBLEM TO BE SOLVED: To shorten image output time by electron emission of a cathode ray tube by enhancing absorption of heat from a heater in a cathode structure which is of a type where a cathode substrate metal is fitted against the inner surface of a cathode sleeve, and by preventing heat loss by radiation. SOLUTION: This cathode ray tube has a vacuum envelope composed of a panel having a fluorescent screen, a neck storing an electron gun, and a funnel connecting the panel and the neck. The electron gun has a cathode 40 with a structure where a cathode substrate metal 41 is fitted with and held at one end of a cylindrical cathode sleeve 43 and where a heater insertion opening is formed at the other end. In this case, in the cathode 40, the diameter of the cylindrical cathode sleeve 43 is smaller at a part or all part of one end than at the other end and, in a heater 31, the diameter of a heating part wound in a coil form is smaller than that of a leg part and, when inserting the heater 31 into the cylindrical cathode sleeve 43, thermal efficiency is enhanced by tightly contacting a small diameter part of the cylindrical cathode sleeve 43 with the coil part of the heater 31.  Heat loss by heat radiation is reduced by reducing the diameter of the cylindrical cathode sleeve 43 near an electron emissive material layer.

IPC: H04L25/40
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To attain data communication at an optimum transfer speed for a transmission line even when a capacitive load of the transmission line is fluctuated by using a timer counting a rising of a serial clock so as to sample serial data at a receiver side with a prescribed time of delay from the serial clock. SOLUTION: A time from the rising of a serial clock till a sampling point of serial data is registered in advance in a register 2. A counter 1 counted by a high speed clock is reset at a rising of a serial clock and the count is proceeded while the serial clock is at a high level. A comparator 3 outputs a latch signal when a value of the counter 1 reaches a setting value of the register 2 and a data latch 4 stores serial data at that point of time. The characteristic of the transmission line is discriminated by deciding a setting value so that the sampling clock 5 is at a high level when the sampling clock 5 is confirmed after the clock is arisen.
