Abstract: 1275241 Spot-type disc brakes; hydraulic slack adjusting; self-servoaction; manual and hydraulic TOYOTA JIDOSHA KOGYO KK 6 Jan 1970 639/70 Headings F2E and F2F In a spot-type disc brake for vehicles the carrier plate of a friction member urged by a piston in an hydraulic cylinder is slidable relative to the piston in the direction of rotary movement of the disc and perpendicular to the direction of piston force; an L-shaped lever pivotable about an axis stationary with respect to the cylinder has arms extending respectively to a side surface of the carrier plate and the end of the piston remote from the carrier plate so as to transfer the "sideways" force from the carrier plate to the piston to increase the discengaging force and thus provide a servo action. In operation, hydraulic fluid admitted at 64 moves ball 60 off its seat against the force of spring 62 and enters chamber b, imparting pressure to the main piston 34, which forces friction member 12 against disc 10, the disc moving in direction C. The frictional engagement of the friction member 12 with the side of the disc causes the friction member to move laterally with the aid of roller bearings 32 in direction D, whereupon the end of plate 24 in contact with the end 74 of an arm 70 of a lever 66 forces the lever 66 to pivot clockwise about its pivotal connection 68 with yoke 16. In consequence, end 76 of the other arm 72 of the lever presses the end of an auxiliary piston 40, against the force of a spring 78, thereby intensifying the pressure on the main piston 34 and consequently on the friction member. Where, as shown, a second friction member 14 is provided, it is caused to exert braking pressure first by reaction through cylinder 36 and the yoke 16 to which the cylinder is secured, and is further acted upon by the yoke directly when lever 66 is moved because the forces acting on the pivot 68 of the lever cause the yoke to be pivoted clockwise about its pivotal connection 20 with the stationary bracket 18. The brake may be maintained in engaged or parked condition manually and mechanically by pulling on a headed wire 82 engaging an extension 80 of lever 66. A second lever 84, similar to lever 66 but not provided with a wire connection, is provided for the self-servo action when the disc 10 is rotating in the reverse direction. The same spring 78 acts on this lever. Spring 78 acts as the brake-release spring. A one-way valve 60 feeding a space b between pistons 34 and 40 causes progressive separation of the pistons for wear compensation.

Patent HK-17786-A (HK)
Title: Very low current pierce oscillator
Inventor: LEWYN LANNY L
IPC: H03B5/36
Filed: 1986-03-13
Abstract: A very low current Pierce oscillator has two pairs of complementary field-effect transistors (FET's) and a two-terminal quartz crystal. The gates of the first complementary FET pair are coupled through individual capacitors to one terminal of the quartz crystal, their drains being connected together and to the other quartz crystal terminal. Current flow through the crystal oscillator is minimized by a novel oscillator bias loop connected between the gates of the first FET pair. Amplification is provided by the second FET pair which have a commonly connected drain comprising the oscillator output node. The gates of the second FET pair are each connected to a respective one of the gates of the first FET pair. The oscillator bias loop minimizes the source-to-drain current through the first FET pair by reducing the P-channel FET gate voltage in response to the source-to-drain current. The oscillator bias loop assures reliable start-up by permitting the oscillation of the source-to-drain current to increase freely to some large magnitude and then operates to reduce the amplitude of the oscillation and also the dc bias level of the current to an equilibrium condition. Means are provided for preventing elements within the oscillator bias loop from overloading the oscillator or otherwise preventing the initiation of oscillation at start-up.

Title: Data transfer system
Inventor: KAMIYAMA TOSHIHIRO
IPC: H04L7/04
Filed: 1984-01-04
Abstract: PURPOSE:To decrease sampling mistakes even in a data transfer at high speed for a comparatively long range by providing a delay means for giving a delay to a reception timing signal inputted from a pulse generating means at predetermined finess. CONSTITUTION:A pulse generator PG generates a transmission timing signal ST 2' and a reception timing signal RT' in phase at first. Reception data SD is delayed by a time DELTAT from a transmission timing signal ST2 and reaches a receiver as reception data RD. On the other hand, the reception timing signal RT' is inputted to delay time setting circuits DT1, DT2 via a delay circuit DL1 while being delayed in predetermined finess (e.g., in the unit of 10+1sec). The delay time setting circuits DT1, DT2 select the input from the delay circuits DL1, DL2 so that the final reception timing signal RT is delayed by the time DELTAT from the transmission timing signal ST2.

Title: Detecting method for completion of washing of material to be washed
Inventor: IKEDA SHIGERU
IPC: H01L21/304
Filed: 1985-01-08
Abstract: PURPOSE:To wash a material to be washed positively by a minimum quantity of pure water by completing washing when the resistivity value of pure water before washing the material to be washed and pure water after washing reaches a set value. CONSTITUTION:A carrier 3 holding masks 2 is housed into a washing tank 1, and pure water is fed into the tank 1 from a supply pipe 4, and discharged to a discharge pipe 5. Since a difference is formed between the resistivity values of resistance meters 6 and 7 at a point of time when the washing of the masks 2 is started, a solenoid valve 9 is opened, and pure water continues to be fed. Since an electrolyte is removed from the masks 2 in a short time, the resistivity values of the resistance meters 6, 7 gradually reduce or do not change. The time displays the completion or limit of washing, and the solenoid valve 9 is closed and washing is completed when the resistivity values reach a set value set to a controller 8. Accordingly, a material to be washed is washed positively while the consumption of pure water more than required can be prevented.
