Title: Print head for wire dot printer
Inventor: SAITOU MASAHARU
IPC: B41J2/28
Filed: 1984-04-13
Abstract: PURPOSE:To eliminate wear or noise by interposing polyether ketone film between members which generate mechanical contacting stress and heat repeatedly between the members for driving the wire of a print head. CONSTITUTION:When an armature 26 is returned from the released state to attracted state in a spring charge type print head 18, it is vigorously collided with the attracting surface of a core 24 to wear the attracting surface to cause a noise. Accordingly, a polyether ketone film 32 is interposed between the attracting surfaces of the armature 26 and the core 24. In this case, the portion that mechanical contacting stress is applied is limited to the attracting surfaces of the armature 26 and the core 24. Thus, the film 32 may be interposed sufficiently on the portion. Here, the armature 25 is attracted and held by the core 24, and the first and second yokes 19, 20 and spacer 28 are formed on the annular outer wall 22. Therefore, the film 32 may not be necessarily bonded with an adhesive.

Filed: 1992-03-30
Abstract: PURPOSE:To perform easy and rapid mounting or an air bag on a retainer by inserting the pin of a press ring in the pin insertion holes of the retainer and the air bag and fixing a press ring to the retainer through locking of an expansion part at the tip of the pin to the retainer. CONSTITUTION:A pin 50 is protruded from a press ring 20 and the pin 50 is inserted through the pin insertion holes 56, 58, and 60 of an air bag 16, a retainer 10, and the flange part 14. The tip part of the pin 50 forms an expansion part 52 and a slot 54 is formed in the tip thereof. The diameter of the expansion part 52 is larger than those of the pin insertion holes 56, 58, and 60 but the expansion part 52 can pass through the insertion holes 56, 58, and 60 because of the slot 54. The expansion part 52 passing through the pin insertion holes 56, 58, and 60 is expanded through its resiliency, and the expansion part 52 is locked to the edge part of the pin insertion hole 60. Since the press ring 20 can be mounted on the retainer 10 through one action, this constitution causes execution of an easy and rapid mounting work.

Title: Signal transmitting device of pulse width output detector
Inventor: GOTOU YUUICHI
IPC: G08C19/22
Filed: 1984-04-13
Abstract: PURPOSE:To commonly use wiring for connecting a detector and a control device and to reduce the quantity of wiring, by transmitting detected information through a pulse width signal and indicating a device number through the number of pulses. CONSTITUTION:A pulse width signal outputting circuit 1 always converts information detected by a detector 2 into pulse width signals and outputs the pulse width signals to one input terminal of an AND gate 3. Upon receiving a transmission starting signal at a terminal 4a from a device in the upstream side, a flip flop circuit 4 is set and the gate 3 is opened. As a result, the pulse width signals are sent out to a transmission line. When it is detected that the number of sent-out pulses coincides with a device number, a number of pulses deciding circuit 5 resets the flip flop circuit 4 and stops the sending out operation of the pulse width signals. At the same time, the circuit 5 controls a starting signal outputting circuit 7 to send the transmission starting signal to a device at the downstream side.

Title: Air conditioner for vehicle
Inventor: NIIMI YASUHIKO
IPC: B60H1/32
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a hybrid-type air conditioner for a vehicle, in which an engine as well as an electric motor are used as the driving source for a compres sor, which can maintain both good air conditioning performance and accelerating performance, which can cleanse the exhaust gas at the time of both quick and gentle acceleration which can save the electric power, and which can restrict an increase of the size of a car-mounted battery. SOLUTION: Whne a vehicle-state judging means 10 judges that a load exceeding the slow acceleration is being given to an engine 2, a driving selecting part 11 turns a clutch 4 off in order to perform 'acceleration-cut', in which a compressor 1 is driven by an electric motor 3. In this case, the smaller the engine-load, or the larger the cooling load, the shorter the time for the 'acceleration-cut' is set. Thus, the electric power consumption can be reduced, while an increase of the size of a battery can be restricted, compared with the case in which the electric motor 3 is operated simply up to the gentle acceleration.
