Patent JP-H03186717-A (JP)
Title: Cryogenic flowmeter
Inventor: WACHI YOSHIHIRO
IPC: G01F1/68
Filed: 1989-12-18
Abstract: PURPOSE:To decrease the thermal disturbance or the flow resistance to a fluid, and also, to decrease the measurement error simply and at low cost by measuring a time difference by which the temperature variation or the pressure variation of the fluid heated by a heating means passes through two points of the downstream side. CONSTITUTION:When a current is allowed to flow to an induction heat coil 2 by pulse discharge from a pulse power source, part of a piping 1 is heated, and the temperature of a fluid flowing through the inside of the piping 1 rises. Also, propagation speed of a temperature variation of a liquid can be put so as to be equal to a flow velocity by taking a distance L between two points A, B to a value which can disregard a temperature rise in the longitudinal direction caused by thermal conduction of the piping. As a result, a flow velocity (v) can be given by v=L/t2-t1=L/DELTAt by putting as t2-t1=DELTAt. In this regard, t1 and t2 denote the time when a temperature variation of the fluid is generated. Subsequently, when the flow velocity (v) is measured, temperature and pressure of the fluid can be measured by a thermometer 5 installed between A and B and a pressure sensor attached to the tip of a connecting tube 6, and a material value in its state can be known.

Title: Copying machine
Inventor: ARAKI KAZUHIRO
IPC: G03G15/00
Filed: 1987-12-23
Abstract: PURPOSE:To prevent a shadow part from being developed and to prevent a black stripe from occurring in an image by providing a control means for stopping the toner supply of a developing device to a photosensitive body for a specified time in the middle of developing when information that it is a mask mode is given. CONSTITUTION:A signal from the mode indication switch (information offering means) 203 of an operation panel 202 is inputted in the input port of a CPU 200. The mode indication switch 203 is turned on when a user requires that the shadow part occurring in the center should be deleted from the image in case of copying an object like a book and it transmits the information that the mode is a mask mode to the CPU 200 based on the requirement. When the mode indication switch 203 is off, the information that the mode is a normal mode is transmitted to the CPU 300. Thus, the black stripe caused by the shadow part can be prevented from being reproduced on the image on copying paper.

CONSTITUTION:A core member for a platen roller to be mounted on, for example, a dot matrix printer comprises a shaft part 10 and a cylinder part 20 which are connected to each other by a predetermined number of ribs, preferably, five ribs 31-35. The core member is obtained by integral extrusion from, for example, a light aluminum alloy. The ribs 31-35 are extended radially, with respect to the axis of the core member, between the shaft part 10 and the cylinder part 20 disposed concentrically with the shaft part 10. The inner and outer ends of each of the ribs are connected respectively to the shaft part 10 and the cylinder part 20, thereby defining cavity parts 40 between the ribs and both the shaft part 10 and the cylinder part 20. The ribs 31-35 are disposed at irregular angular intervals. Therefore, the requirements for generation of at least a portion of lower to quite higher order vibrations, in a radial nodal mode and an annular vibrational mode, are not satisfied.
