Title: Water cooled thyristor valve
Inventor: FUJIMOTO TAKAFUMI
IPC: H01L23/473
Filed: 1993-03-04
Abstract: PURPOSE:To supply cooling water whose amount is suitable to a load and save electric power of auxiliary equipments wherein a cooling equipment is main, by controlling the amount of cooling water according to the operation state of thyristor valves. CONSTITUTION:A direct current is detected by a DC detector 2. On the basis of the direct current, a control equipment 3 determines the optimum amount of cooling water of thyristor valves 1U-1Z. According to the command value of the optimum amount of cooling water, the cooling water is sent from a cooling equipment 4. The cooling water is sent to the thyristor valves 1U-1Z, via cooling water pipes 5A, 5B. Thus cooling is performed. After cooling, the cooling water is returned to the cooling equipment 4, via the cooling pipe 6, and again used as cooling water after heat exchange. Since the amount of cooling water required for cooling the thyristor valves 1U-1Z can be obtained from the operation state of the thyristor valves 1U-1Z, it is not necessary to circulate the cooling water more than the necessary amount, so that the load of the cooling equipment 4 is reduced and electric power can be saved.

IPC: G11C11/407
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To prevent the circuit area of a timing generator from being increased greatly even if the number of banks increases. SOLUTION: The one-shot signal generating section 2 outputs one-shot pulse signals RTOA0-RTOA7 in accordance with change in row address activating signals RASB0-RASB7, setting latch circuits 60 -67 . Then, these signals are encoded in the encoding section 3, converted into four signals, and decoded to the initial signals at the decoding section 5 after being delayed for a specific time at the inter-bank shared timing forming section 4, with the latch circuits 60 -67 reset. At the time of refreshing, the refresh timing forming section 1 operates, and all bank activating signals RTO0-RTO7 are outputted. As a result, even for eight banks, five delay elements 410 -413 are sufficient.

Title: Package for housing electronic components
Inventor: IRYO KENJI
IPC: H01L23/10
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a compact and high-air-tightness package for housing electronic components which never causes a flange to peel off or an insulation base to crack at welding even when the outline size of the flange is small. SOLUTION: The package comprises an insulation base 1 having a mount 1a for an electronic component 4 at the top face, a flange 9 which is fixed to the base 1 and has a periphery protrudent to the outside of the base 1, and a metal cap 2 having a flange 2a having approximately the same size as the flange 9 and welded to the periphery 9a of the flange 9. In this case, the periphery 9a is made thicker than other regions. This well relieves the thermal stress in welding, ensures a mechanical strength enough to avoid breaking the air- tightness of the package.

Title: Dynamic type semiconductor memory device
Inventor: IHARA MAKOTO
IPC: H01L27/108
Filed: 1990-02-22
Abstract: PURPOSE:To shorten time from the start of a sense operation to the external output of data by executing the amplification of potential difference between bit lines, the output of the amplified potential difference from a sense amplifier to a data line and the restorage of the bit line in this order after receiving a start signal by a timing generation circuit. CONSTITUTION:Based on the timing of control signals (a)-(c) to be determined by the constitution of a timing generation circuit 1, the amplification of the potential difference between bit lines 7, the output of the amplified potential difference from a sense amplifier 3 to a data line 5 and the restorage of the bit line 7 is executed in this order. In such a case, since the sense amplifier 2 is connected to the data line 5 when starting the restorage of the bit line 7, the period from the start of the sense operation to the output of the data to the data line 5 can be limited only in the operation time for amplifying the potential difference of the bit line 7 by a pull-down transistor. Thus, the time until the output of the data to the external part can be shortened.

Filed: 1989-02-28
Abstract: PURPOSE:To correctly restore a multilevel AM signal by digitizing the multilevel AM signal up to insignificant bits which are lower in order by one bit more than the number of bits before its modulation and referring to the insignificant bits as the feedback of a bias voltage. CONSTITUTION:An A/D converting circuit 2 has (N/2+1)-bit converting ability and is equipped with a low-pass filter(LPF) 3 which converts the least significant bit of the A/D converting circuit 2 into a DC signal with a time constant of low frequency. The multilevel AM signal is digitized up to the insignificant bits which are lower in order by at least one bit more than the number of bits before the modulation and this converted DC signal is inputted to the negative input of the operational amplifier 6 of a DC bias circuit to feed the DC bias back. Consequently, the multilevel AM signal can correctly be restored without being affected by temperature characteristics nor a secular change.

Abstract: PURPOSE:To spread the solution of termite-proof agent or the like up to the remote side of a cable wiring conduit line and shank-way-internal space by feeding gas to the external side of a solution pipe in the inseting pipe of high rigidity. CONSTITUTION:Into the inserting pipe 1 of high rigidity having thickness for enabling the pipe to be inserted into a cable wiring conduit line, a shank-way- internal space, or the-like, a solution pipe 2 is inserted.

Title: Pendulum holding structure of clock

IPC: G04B45/00
Filed: 1994-03-16
Abstract: PURPOSE:To maintain the pendulum of a clock at a specific angle against the main body of the clock even when the main body is inclined forward or backward to some extent so that the operation of the pendulum can be continued stably and the degree of freedom in the design of pendulum clocks can be improved by holding the whole body of the pendulum by utilizing the magnetic force of a magnet. CONSTITUTION:A magnet 5a is installed to either the holding member 3 of the main body 2 of a clock or the holding section 5 of a pendulum 4. Then the contacting part with the magnet 5a of the section 5 or member 3 is formed in two or more projected contacts or a long shaft arranged on a line perpendicular to the oscillating plane of the pendulum 4. Since the whole body of the pendulum 4 is held by utilizing the magnetic force of the magnet 5a, the contact between the member 3 and section 5 can be maintained in the same multipoint contact or linear contact as that when the main body 2 is not inclined even if the main body 2 is inclined forward or backward when the pendulum operates. In addition, the positional relation between the pendulum 4 and main body 2 can be maintained, because the pendulum 4 itself is also inclined. Therefore, a thin pendulum clock which may be inclined forward or backward and a pendulum clock which is inclined forward or backward in advance can be designed and the degree of freedom in design can be improved.
