IPC: F01L13/00
Filed: 1992-12-22
Abstract: PURPOSE:To prevent a locker arm from falling off to the side of a low speed cam by providing a tapered member on a cam so that width of the cam in the axial direction is expanded toward the head end of a projection part of the cam. CONSTITUTION:A tapered member 21 is provided on a high speed cam 20 so that the width of the high speed cam 20 in the axial direction is expanded toward the head end of a projection part 20b of the high speed cam 20. In the case when an engagement part 16a of a locker arm 16 runs on the high speed cam 20 roughly in the neighbourhood of a boundary of a base circle 20a and the projection part 20b, an engagement area of the engagement part 16a with the high speed cam 20 increases in accordance with rotation of a camshaft 18. Consequently, the balance of the engagement part 16a on the way of running on is maintained, and possibility of the engagement part 16a of the locker arm 16 falling off to a low speed cam 19 is lowered. When the engagement part 16a reaches the head end of the projection part 20b of the high speed cam 20, the engagement part 16a comes to be in the state where it runs on the high speed cam 20 by specified width. Accordingly, possibility of the locker arm falling off to the low speed cam is lowered.

Title: Temperature measuring device
Inventor: ANDO MIGIWA
IPC: G01K11/12
Filed: 1993-12-14
Abstract: PURPOSE:To provide a temperature measuring device not affected by electromagnetic induction disturbance. CONSTITUTION:After pealing coating material 13 and clad material 12 at the tip of a photofiber P1, a reflection mirror 14 is provided at the tip of a core 11. The exposured core part is claded with a copper pipe 15 sealed at the tip end and charged inside with oleic acid 16 to form a temperature and light characteristics converter part 10. When the temperature around the converter part 10 rises, the refractivity of oleic acid lowers. If light is introduced from the light source into the photofiber, the light intensity transmitting into oleic acid from the core reduces and light intensity transmitting in the core increases. This light intensity is measured with a light power meter 23. Since the light intensity and the surrounding temperature are proportional, temperature measurement with a high sensitivity and high accuracy is possible by measuring the light intensity. Thus, by measuring temperature by means of light, reliable temperature measurement without being affected by electromagnetic induction disturbance is possible.

IPC: H04B7/26
Filed: 1989-12-29
Abstract: PURPOSE:To attain communication in an emergency not through a base station by using an emergency switch so as to select simplex and duplex talking. CONSTITUTION:A slave set is in talking with other slave set via a base station normally at a frequency in the duplex mode, and when the base station is faulty, a slave set operates an emergency switch 38 to throw forcibly a simplex/duplex transmission reception changeover device 33 to the position of the simplex SMP thereby receiving a frequency f1. When the user of the slave set depresses a talk switch 37, a transmission reception antenna changeover switch 26 is thrown to the position of a receiver RX the same as the case with the duplex mode and a CS reception section 31 receives the same frequency f1 as the transmission frequency. Thus, the simplex talking with reception priority is started when a reception carrier is not sensed. Thus, the slave set makes simplex talking with other slave set not through the base station by the operation of the emergency switch 38.

IPC: F24H1/00
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To accurately detect a circulation flow rate of a heat medium in a non-hot water supply side circulation path such as reheating circulation path. SOLUTION: When temperature detected by a temperature sensor 33 for hot water to be supplied by heat exchange exceeds OFF temperature, combustion with a burner is stopped by a single reheating operation combustion control section 45, and the combustion with the burner is restarted when it falls below ON temperature. The circulation flow rate of hot water of a reheating circulation path is detected by a reheating circulation flow rate detecting means 48, based on the temperature detected by the temperature sensor 33 for hot water to be supplied by heat exchange as varying with the burner combustion, a flow rate detection data previously applied and the temperature detected by a bath temperature sensor 37. The presence of supplied hot water leaked during the single reheating operation is judged by a leaked hot water supplied detecting section 49.  When any leak of the supplied hot water is detected, the flow rate detected by the reheating circulation flow rate detecting means 48 during the single reheating operation before the detection of the leaked hot water supplied is decided as circulation flow rate of hot water in the reheating circulation path, by a reheating circulation flow rate deciding means 46.
