Title: Method for measuring transmittance of original of diazo copying machine
Inventor: SHIMIZU HIROSHI
IPC: G03B27/72
Filed: 1990-09-20
Abstract: PURPOSE:To more exactly measure the transmittance of an original by measuring the transmittance of the inserted original by the light source light quantity detected when a 1st original detecting means detects the original and the transmitted light quantity detected when a 2nd original detecting means detects the original. CONSTITUTION:A light quantity detecting section 10 is held always in an operating state to store the light quantity detected when the 1st original detecting means 20 detects the original P as the light source light quantity I0, to store the light quantity detected when the 2nd original detecting means 30 detects the original P as the transmitted light quantity I and to measure the transmittance of the inserted original P by the stored light source light quantity I0 and the transmitted light quantity I. Then, the time after the light source light quantity I0 is stored before the transmitted light quantity I is stored is the short time by the operation that an operator inserts the original into the device and the light quantity just before the original is inserted is stored as the light source light quantity I0. The transmittance of the original is more exactly measured in this way.

Title: Friction lining material for automatic transmission
Inventor: KANI HARUNOBU
IPC: F16D69/00
Filed: 1987-10-01
Abstract: PURPOSE:To effectively prevent the scattering of automatic transmission oil and to improve the durability of the transmission by dividing the friction lining material into parts having a large and a small porosity respectively in a ring- shape, and forming them so as to have the porosities continuously increased and decreased. CONSTITUTION:A ring-shaped friction lining material 1 is adhered to a core plate 4, and a part 2 having a large porosity (for example 40%) is provided on the side of an inner periphery, and a part 3 having a small porosity (for example 20%) on the side of an outer periphery. When an engine is in rotation, automatic transmission oil flows from the center of the ring-shaped friction lining material 1 outward through its inside, but since the part 3 having the small porosity is provided outside, the oil is restricted in its circulation for preventing scattering, and the part 2 having the large porosity reserves a large quantity of the oil. In addition to that, continuous increase and decrease in the porosity from the inner periphery toward the outer one can produce more effective result. Thus reliable seizure preventing effect can be obtained independently of the number of engine revolutions to improve the durability of a transmission.

Title: Card-type automatic vending machine
Inventor: WATANABE KIYOSHI
IPC: G07F7/08
Filed: 1994-10-14
Abstract: PURPOSE: To eliminate the need of switching an automatic vending machine to be in sales stop state even if an operation abnormality occurs by storing card information identifying a use card detecting that a sales operation has not normally terminated, detecting it and compensating for sales. CONSTITUTION: A sales processor 3 reads the ID code of an IC card 1 inserted into a card processor 2, instructs a ticket issuing device 6 to issue ticket, and instructs the card processor 2 to update the prepaid amount of the IC card 1 to an amount obtained by subtracting the sales amount at that time. Then, it is judged whether the normal ticket-issuing processing has been completed or not. When it is judged to be abnormal, the read ID code is written into the failure area of a control data memory 4, and a processing is shifted to a next user without switching the vending machine to be in the sales stop state. When the IC card 1 by which the sales operation has not been normally terminated, is inserted into the card processor 2 of the same ticket issuing machine, the ID code concerned is judged to exist and the compensation by free sales is executed.

Title: Method and device for detecting center position of welding groove or bead
Inventor: KUSUNOKI MITSUHIRO
IPC: B23K9/095
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To accurately detect a groove shoulder or a bead edge from a one- dimensional cross-sectional form by applying straight lines or N-dimensional polynomial curves one by one along the cross-sectional form of a subject for measurement, and judging the difference between them. SOLUTION: A straight-line application circuit 50 in groove shoulder/bead edge detecting device 40 applies straight lines or N-dimensional polynomial curves one by one along a cross-sectional form detected by an image acquisition system, in such a way that either of them is minimized. A square remainder calculating circuit 52 calculates a square remainder which shows the difference between the applied straight line and the cross-sectional form. A groove shoulder/bead edge judging circuit 54 judges the cross-sectional form to be that of a groove shoulder or a bead edge when the square remainder becomes equal to or greater than a predetermined value. Based on the judgment result, a bevel center serving as the center of the groove shoulder or a bead center serving as the center of the bead edge is recognized, and a groove center/bead center signal is output from a groove center/bead center recognition circuit 56.

Abstract: PURPOSE:To decrease a heating temp. without reducing the accumulative quantity of heat and pressure given to a toner image and to protect a photosensitive drum being weak in the heat by adding the heat and pressure for fixing a toner image transferred on a recording sheet from an image carrier in two operations. CONSTITUTION:A cartridge 1 and a fixing unit 10 are moved in a state where they are lowered downward, when printing is carried out, and the photosensitive drum 2 and a fixing roller 9 are rotated while being in contact with a printing sheet 14. The cartridge 1 is moved to the upper position by the action of a first vertical moving mechanism 23 when a returning operation is carried out, and only the fixing roller 9 is in contact with the printing sheet 14. When the heat and pressure are given to the toner image transferred on the recording sheet 14 from the image carrier 2 to carry out thermal fixing, the heat and pressure are added dividedly in 2 operations. At this time, the fixing properties of the toner image transferred on the recording sheet 14 is in proportion to the accumulative quantity of the heat and pressure given to the toner image. Thus, the fixing properties of the toner image are not impaired, and the thermal fixing can be carried out with a suppressed heating quantity.
