Title: Vacuum cleaner
Inventor: TAKAHAGI FUMIO
IPC: H02P3/02
Filed: 1992-02-17
Abstract: PURPOSE:To prevent abnormal temperature rise accurately by arranging a temperature sensor in a space which creates temperature characteristic proportional directly to the maximum temperature within an electric cleaner formed by arranging the cooling plate and a temperature protector on a housing surface on the side of the cooling plate at a part of an exhaust passage of an electric blower. CONSTITUTION:Cooling air sucked with a fan 14 at an air suction port of an electric blower 8 of am a vaccum cleaner is exhausted at exhaust ports being shunted as indicated by the arrow. A cooling plate 36 is arranged at a part of a cooling air path 34 made up of a stator core 29 and a housing 20 covering about a half of the path 34 to form a space where no cooling air flows. A temperature protector mounted on the housing 20 is actuated by an output of a temperature sensor arranged in the space. Thus, an output of the temperature sensor becomes proportional directly to the maximum temperature in the cleaner thereby preventing abnormal rise in the temperature with the accuracy of temperature control improved at a low cost.

Patent JP-S57144647-A (JP)
Title: Feed speed control unit for cutting machine
Inventor: INABA HAJIME
IPC: B23Q15/12
Filed: 1981-03-03
Abstract: PURPOSE:To make it possible to detect cutting failure in any early stage by comparing the output of threshold value of load change rate setting member with the output of load change rate detecting member and hence judging whether a large load fluctuation is caused either by the failure of tool or the failure of feed speed control. CONSTITUTION:When a load signal S1 is (markedly) deviated from a target load signal S2 at time t2, a difference signal S3 is deviated from an allowable range  R. A feed speed setting circuit 24 transmits an override signal S4 to a cutting  tool 1 as a directive to reduce the feed speed and also outputs a drive signal  S4' to a failure detecting member 3. If the load signal S1 fails to fall quickly  even when the feed speed is reduced, the value of a load change rate signal S5  will exceed a threshold value S6' thereby allowing a comparison circuit 33 to  transmitt a failure detection signal S7. When load fluctuation are caused by  feed speed control, the value of the S5 is smaller than the value of S6' and  hence the failure detection signal S7 is not transmitted. With this construction,  the failure of tool can be detected.

Title: Fm detecting circuit
Inventor: IENAKA MASANORI
IPC: H04B1/10
Filed: 1979-03-16
Abstract: PURPOSE:To simplify an FM detection circuit, using a multiplying circuit, by making use of the switching circuit of the detecting circuit for muting operation. CONSTITUTION:An FM detecting circuit using a multiplying circuit is composed of differential amplifying transistors TRQ1 and TRQ2, differential switching TR's Q3 and Q4, and Q5 and Q6, capacitors C1 and C2, and a phase shifting circuit of coil L, etc. Then, decision circuit 2 detects the signal level of IF amplifying circuit 1 to generate a muting signal, by which TRQ7 is controlled. Therefore, when TRQ7 conducts through decision circuit 2, the phase shifting circuit drops down to the earth potential via switch SW and bases of TR's Q3 and Q6 are both held at the earth potential, so that switching TR's Q3 and Q6 will be OFF without reference to the muting signal. As a result, the multiplying circuit serves as a mere amplifying circuit, providing muting operation. Thus, the detecting circuit can be simplified.

Title: Control clock/frame pulse selector
Inventor: SUZUKI YOSHIYA
IPC: H04L1/22
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a control clock/frame pulse selector for supplying a high- reliability control clock or frame pulse with the cascade connection of plural selectors. SOLUTION: A selection switching signal SEL 2 for preceding selectors 1 and 2 is inputted to a quality managing part 5 for monitoring control clocks C and D to be inputted to a following selector 3. When the preceding selector 1 detects the fault of a control clock A and starts outputting the selection of a control clock B, the quality managing part 5 is controlled by the selection switching signal SEL 2, and monitoring is started synchronously with the new control clock or frame pulse. Thus, when the selection of the preceding selector 1 or 2 is switched even in the case of the number of protective steps for the preceding selector 1 or 2 less than the number of protective steps for the following selector 3, the quality managing part 5 for the following selector 3 immediately starts monitoring synchronously with the inputted control clock or frame pulse.  Therefore, non-monitoring time can be minimized.
