IPC: H01J9/22
Filed: 1987-06-26
Abstract: PURPOSE:To prevent the deformation of a glass tube by holding the straight tube type glass tube with jigs having glass tube mounting sections made of quartz or ceramic with the heat resistance and nearly the same thermal conductivity as the glass tube and heating it in a baking furnace. CONSTITUTION:A jig 3 has the heat resistance and is not deformed at the baking temperature in a baking furnace 2 and made of a circular pipe of quartz or ceramic with nearly the same thermal conductivity as a glass tube 1. The glass tube 1 is stably held in line contact with glass tube mounting sections m1, m1 with linear outer peripheries of two adjacent jigs 3, 3, when they are heated at the baking temperature in the baking furnace 2, the glass tube 1 and jig 3 have little temperature difference because both of them have nearly the same thermal conductivity, the jig 3 is not deformed by heat, and the glass tube 1 is linearly held in line contact with this jig 3. The warping of the glass tube 1 is thereby prevented, and the fluorescent film inside the glass tube is baked satisfactorily.

IPC: G06Q50/16
Filed: 1993-06-30
Abstract: PURPOSE:To dispense with the change of visitor information and to prevent illegal entrance/exit from occurring by discriminating whether or not the visitor information is valid only for a time from the start of visit to the end of it instructed by a commander. CONSTITUTION:When a visit schedule to a specific area is planned, commander information such as commander ID information, etc., a visit schedule date zone, and the visitor information are inputted from an input part 16, and they are registered on a RAM. In such a case, the visit schedule date zone is set at a wide time zone so as to include an actual visit time zone. In this way, it is not required to change a registered time even when actual time to start and end the visit is shifted before or behind scheduled time. When the visitor information is inputted by inserting a visitor card to an insertion port 13 or operating an ID number on a ten key part 12, it is discriminated whether or not a visit start instruction is issued by operating a start switch 14 after inserting a commander card by the commander. In such a case, when it is discriminated that no instruction is issued, no unlock signal is outputted from a control part 11, which enables a door to be locked.

Title: Defective or nondefective decision of constant velocity coupling
Inventor: KIKUCHI TOKIO
IPC: G01M13/02
Filed: 1989-06-26
Abstract: PURPOSE:To improve efficiency in judging whether a constant velocity coupling is acceptable or not by calculating the value of a rotating torque at the given inclination of an inner member from the curves representing a relationship between the maximum and minimum torque values and the inclination of the inner member and comparing the rotating torque values with a predetermined reference value to judge whether the constant velocity coupling is acceptable or not. CONSTITUTION:The inner member (b) of a constant velocity coupling A is continuously inclined to its maximum inclination while being rotated. The curves of the maximum and minimum torque values with respect to inclinations are calculated from the data of the rotating torque values and the inclinations measured at every given rotational angle when the inner member (b) of the constant velocity coupling A is inclined. Then, the maximum and minimum values of the rotating torque at the given inclination are calculated from the curves thus obtained. Whether the constant velocity coupling A is acceptable or not is judged by comparing the maximum and minimum values with reference values. Thus, whether the constant velocity coupling A is acceptable or not can be efficiently judged by a calculation from the measured data when the inner member (b) is inclined.

Title: Corrector for calorific value of fuel
Inventor: TAKATSUKA YOSHIHISA
IPC: F23N5/00
Filed: 1981-10-09
Abstract: PURPOSE:To optimize the operation corresponding to load regardless of the calorie of fuel by automtically correcting steam pressure, etc. even when fuel changes. CONSTITUTION:When the kinds of fuel change, stationary deviation resulting from the variation calorific value is formed as the output of a comparison computing element 3 in steam pressure. Deviation signals from a regulator 4 are added to a fuel command by means of an adder 6, and flow rate is altered by means of a comparison computing element 10, a regulator 11 and a fuel flow- rate control valve 12. Consequently, since the fuel flow-rate command of a calorie base transmitted from a function generator 5 and the measuring value of a flow-rate base from a fuel flow-rate detector 7 differ, deviation is outputted from a comparison computing element 13, integrated by means of an integrator 8, transmitted to a multiplier 9 as a coefficient correcting flow rate, multiplied by fuel flow-rate measuring value from the fuel flow-rate detector 7, and transmitted to the comparison computing element 10. Accordingly, flow-rate control signals are transmitted to the control valve 12, and the opening of the valve is controlled until deviation reaches zero.
