Title: Supply device of cooling water in multistage mechanical seal
Inventor: UEDA MASAYUKI
IPC: F16J15/34
Filed: 1984-05-21
Abstract: PURPOSE:To maintain a quantity of cooling water to a fixed level even if a pump causes a change of its suction pressure, by independently arranging a pressure reducing device in supply inlets of cooling water to a multistage mechanical seal and providing a channeling system which bypasses the mechanical seal from its cooling water outlet in a low pressure side to the cooling water inlet in a high pressure side. CONSTITUTION:A supply device of cooling water provides pressure reducing devices 8-11 in a cooling waterway system to mechanical seals 4, 5, provided in a rotary shaft 3, while a passage, which bypasses the mechanical seal through a check valve 12 and the pressure reducing device 11, between an inlet of the mechanical seal 4 and an outlet of the mechanical seal 5. Accordingly, a chamber pressure of the mechanical seals 4, 5 comes to be almost in a fixed level by opening the check valve 12 if the suction pressure of a pump decreases. As a result, the supply device can hold the cooling water to a fixed quantity even if the pump causes a change in its suction pressure.

Inventor: KUSUNOKI MICHIHIKO
IPC: H04Q3/00
Filed: 1980-07-24
Abstract: PURPOSE:To realize a core contrast of a subscriber telephone circuit and ensure a highly efficient maintenance and inspection for the subscriber telephone circuit, by detecting both the call and noncall states of the subscriber telephone circuit and then forcibly turning an unbalanced telephone circuit to a balanced one. CONSTITUTION:The subscriber telephone circuits led from an exchange system are connected to terminals 7 and 8 of a main distributing frame MDF. A comparator 11 and a detector 12 connected to a reference power source 10 are connected to the terminal 7, and the voltage of the source 10 is set lower and higher than the voltage of the terminal 7 in the noncall and call states respectively. At the same time, a series circuit of a resistance R1 and a contact 9 of a relay RL3 is connected between the terminals 7 and 8, and the terminal 8 is connected to the circuit 12. Thus the circuit 12 controls the operation of the RL3. Then the output of the comparator 11 drives a relay RL via an FF13 in the noncall state under which the voltage of the terminal 7 is higher than the reference voltage of the source 10. And a balanced circuit is forcibly formed between the terminals 7 and 8 by the resistance R1 connected through the contact 9. In such way, both the maintenance and inspection can be facilitated between the circuits L1 and L2.

Title: Optical disk apparatus
Inventor: MIYAGAWA NAOYASU
IPC: G11B7/00
Filed: 1993-04-27
Abstract: PURPOSE:To obtain an optical disk apparatus wherein a tracking operation can be controlled stably even on an optical disk on which a signal can be recorded both in a recessed part and a protruding part on a track. CONSTITUTION:An offset judgment means 55 judges that a signal has been recorded in only one out of two recording regions which are adjacent in a direction perpendicular to the direction of a track. On the basis of a control signal L3 which is output according to a judged result, an offset application circuit 56 applies an offset voltage to an error signal E1. Thereby, the offset of a tracking error signal generated when a recording pit exists only in an adjacent recording track on the inner circumferential side or the outer circumferential side is offset. Thereby, a tracking operation can be controlled stably. When an address in a recorded region is stored in a recorded address control memory 51, it is possible to detect, by a simple constitution, that a signal has been recorded in one out of the two adjacent recording regions.
