Title: Control method of oxygen concentration sensor
Inventor: MIENO TOSHIYUKI
IPC: G01N27/406
Filed: 1986-03-04
Abstract: PURPOSE:To reduce thermal shock in controlling an oxygen concentration sensor of an oxygen concentration proportional output type by supplying a less current to a heater element during a time period from turning an ignition key on till a specified time elapses than after the specified time period has elapsed. CONSTITUTION:When an ignition switch 37 is turned on, a timer counter in a CPU 47 stats counting from zero and issues a 1st heater current supply command to a heater current supply circuit 51. This energizes a heater element 20 attached to a detection part 1 of an oxygen concentration sensor and the heater element 20 is heated. And when the count of the timer counter reaches a specified time T, a 2nd heater current supply command is issued to increase the calorific value of the heater element 20. And when the count T reaches a 2nd specified time T, a drive command is issued to a dive circuit 46b to supply a pump current to an oxygen pump element 18. This makes detection of oxygen concentration possible.

Title: Emergency braking device for passenger-conveyor
Inventor: KITAMURA SHIGEJI
IPC: B66B29/00
Filed: 1978-04-21
Abstract: PURPOSE: To enable to increase braking force gradually after braking by pressing an elastic body and braking driving rotor by friction therethrough.  
     CONSTITUTION: When a drive chain 3 is broken during descending motion of a passenger-conveyor, a chute 4, contacting with the drive chain 3 and being maintained at a predetermined postion, swings down and thereby a working piece 5 moves and engages with a ratchet wheel 6, and hence the ratchet wheel 6 is stopped. According to this operation, frictional force is generated between the ratchet wheel 6 and an elastic body 10 and braking force is exerted against a driving rotor 7. Simultaneously, the ratchet wheel 6 is shifted toward a direction to press the elastic body 10 through a screw thread 2b, because the driving rotor 7 continues to ratate without stopping immediately by inertia force, and thereby, the elastic body 19 is pressed step by step and the braking force is increased gradually. When the friction between the elastic body 10 and the ratchet wheel6 is balanced with the friction between the screw thread 2b and the ratchet wheel 6, the driving rotor 7 will be stopped by the ratchet wheel 6.

The phase matching conditions are severe with the existing org. crystals including MNA(2-methyl-4-trianiline) and the hardness of their crystals are low and, therefore, crystal processing and grinding are extremely severe. On the other hand, this wavelength conversion element attains noncritical phase matching at the (010) cleavage plane of the crystal and, therefore, the optically good phase matching plane is obtd. without grinding of the crystal which is most important in the element production stages. The shape of the beam is good as well.

Abstract: PURPOSE:To make it possible to measure the flow rate of fluid, whose viscosity and density are changed in a broad range, such as crude oil with high accuracy by using the K factor and the Reynolds number, which are the intrinsic factors of a turbine meter. CONSTITUTION:A turbine meter 4 as the primary instrument for measuring a volume flow rate is provided on an input side 1a of a tube body 1, through which fluid 2 such as crude oil is supplied.

As the proving data, the summarized combination of the Reynolds number (flow speed x tube diameter/kinematic viscosity) and the K factor is stored in a memory. Then, the approximate expression of the relation between the Reynolds number and the K factor is obtained and stored in the memory based on the data. The Reynolds number is computed based on the frequency and the kinematic viscosity from the meter 4. The K factor is obtained by the approximate expression. Thus, the volume flow rate is computed.
