Title: Prevention against tampering of elevator door unlocking fitting
Inventor: GOTO TAKAHIRO
IPC: B66B13/16
Filed: 1994-03-17
Abstract: PURPOSE:To secure the safety of an elevator by setting up a cover, capable of being opened or closed by a hinge, on top of an emergency unlocking device for door opening at an elevator doorway, and installing each stopper, having such a construction as coming off by means of key-insertion, at both sides of the upper part of this cover. CONSTITUTION:A stopper 2, whose one part is inserted into a key guide, and a spring 5 both are installed at both sides of this key guide 4, and a cover 3 capable of being opened or closed by a hinge is installed in the upper part of a key hole. With this constitution, when a key is not yet inserted, the cover 3 is locked by the stopper 2. In the case where a wire 8 is inserted into the key hole, the partial stopper 2 is removable by the inserting position, but all the stopper 2 cannot be removed unless it is regular key form. Accordingly, the cover 3 is in a state of being locked intact, so unlocking by means of tampering cannot be done, and thus door open by tampering is preventable.

Title: Detector for frame synchronization
Inventor: HARADA NAGAYASU
IPC: H04L7/06
Filed: 1985-03-08
Abstract: PURPOSE:To decrease misdetecting times of a frame synchronizing signal by actuating a frame synchronization detecting circuit for a 1-bit period out of a 2-bit period after the bit synchronization is over. CONSTITUTION:A timing circuit 2 contains a signal input terminal D, a clock input terminal T, a signal output terminal Q and a reverse signal output terminal Q' of a D type flip-flop. The signal logic of the terminal Q is inverted for each input of a sampling pulse 12 since the output of the terminal Q' is supplied to the terminal D. However the circuit 2 works only when the bit synchronization detecting signal 13 supplied to a terminal R is equal to logic '1' (showing the end of the bit synchronization). Then the signal of logic '0' is always delivered from the terminal Q to control a frame synchronization detecting circuit 4 under an inactive state in case the signal 13 has logic '0' with the logic of the signal 17 set at '1' respectively (in a bit step-out mode).

Filed: 1983-03-23
Abstract: PURPOSE:To permit stable operation of a wind mill which is always directed to the wind, by controlling and adjusting the deflection phenomenon of being inclined with respect to the wind direction which is generated by the reaction generated through bevel-gear transmission, by a steering vane. CONSTITUTION:When the power supplied from a propeller wind mill 3 is applied onto a generator 12 through a bevel gear, the loading torque increases, and the reaction of the gear torque acts as turning force onto a swivel revolution board 2, and the wind mill 3 tends to operate, titled with respect to the direction of the wind. The loading torque is transmitted to a deflection steering vane 9 through a differential shaft 7 and a gear 8, and acts in the direction for turning- back the propeller wind mill 3. The wind mill 3 is further deflected and increases the retaining force, receiving the reaction of the wind, and thus the wind mill is operated stably, always oppositely directed to the wind direction.

Filed: 1989-02-27
Abstract: PURPOSE:To exclude the effect on circuit operation due to load fluctuation and to eliminate noise of an input signal by mapping a load current of a differential amplifier circuit having an independent reference voltage and varying the reference voltage at the transition. CONSTITUTION:Reference voltage sources 13, 14 outputting 1st and 2nd reference voltages are provided independently. A signal from an input terminal 11 is given to bases of transistors(TRs) QN11, QP15 of 1st and 2nd differential amplifier circuits, and a reference voltage of the voltage sources 13, 14 is given to bases of TRs QN12, QP16 forming a pair of the differential amplifier circuits. Then a current mirror circuit maps a load current at the transition of the amplifier circuit to vary the reference voltage and to give a different threshold level. Thus, the circuit operation having a different threshold level at the leading and trailing of the signal is applied. Thus, the effect on the circuit operation due to load fluctuation is avoided and noise in the input signal is eliminated.

Abstract: PURPOSE:To prevent a connecting tool from getting into a circuit component side and avoid the damage on circuit components by forming partition plates with flange portions which overlap a circuit board and sandwiching the flange portions between a spacer and the circuit board to integrally fixing them. CONSTITUTION:Circuit components 27 and partition plates 45 and 46 which are made of plate metals and get into between circuit components 27 and first- third terminal blocks 31-33, respectively, are mounted to a lower side circuit board 14. The projection heights L of the partition plates 45 and 46 projected from the circuit board 14 are formed larger than those of the first-third terminal blocks 31-33, respectively, and the circuit components 27 on an upper side circuit board 15. Therefore, even if a force applied to a connecting tool drives the tool out of a terminal metal 36 and the connecting tool is about to get into a portion wherein the circuit component 27 is mounted when a variety of wirings are connected to the terminal metals of the terminal blocks 31-33, the tool bits the partition plate 45 or 46 and the further motion of the connecting tool is obstructed.

Abstract: PURPOSE:To indicate that detection is in failure unless a sufficient quantity of photodetection is obtained by making the output of a circuit which calculates a distance constant when a photocurrent discrimination means which discriminates whether a photocurrent is large or small judges that the photocurrent is smaller than a specific value. CONSTITUTION:When the quantity of reflected light beams from an object body 3 is sufficient, the output voltage V1+V2 of an adding circuit 11 becomes higher than the reference voltage of a comparator 12, so the output of the comparator is OV, no current flows to a diode 14, and the output of an arithme tic circuit 8 is sent out by an output circuit 9 as usual. When the quantity of the reflected light beams is small and the output voltage V1+V2 of the adding circuit 11 is lower than the reference value of the comparator 12, the output of the comparator 12 rises and is inputted to the output circuit 9 through the diode 14, so the output of the output circuit 9 is nearly constant.
