Title: Wafer case
Inventor: ENDO MITSUHIRO
IPC: B65D81/24
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To provide a wafer case which is capable of improving sealing properties of the case and automatically eliminating pressure difference caused between the inside and the outside of the case in a relatively short period of time, whose filtering characteristics against dust are high, which prevents a wafer from being damaged due to deformation of the case and dust from adhering to the wafer and, moreover, which is obtained at a relatively low cost. SOLUTION: When the external pressure varies due to some causes to bring about pressure difference between the inside and the outside of this wafer case 10, air flows from a high-pressure side to a low-pressure side through a filter 17 and, as a result, the pressure difference between the inside and the outside of the case is automatically eliminated in a relatively short period of time. Since at least 99.9% of fine dust having a size of 0.05 μm or larger, which is included in the external air, is filtered and removed by the filter 17 at the velocity of filtration V/1500 (mol/minute), dust in the external air does not adhere to the surface of a wafer at the time of eliminating the pressure difference, or the wafer 11 is not marred with a needle-point of a syringe. Moreover, since only the filter 17 is mounted to the case 10, the case is obtained at a relatively low cost.

Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To reduce attenuation in the level of a video intermediate frequency when a peripheral temperature rises by changing the tuning frequency of an intermediate frequency tuning circuit to be higher with the rise of the peripheral temperature. SOLUTION: A television tuner has a frequency conversion part 1 which frequency-converts a television signal and outputs an intermediate frequency(abbreviated as IF signal), an intermediate frequency tuning circuit(abbreviated as IF tuning circuit) through which the IF signal outputted from the frequency conversion part 1 passes and an intermediate frequency amplifier 3 amplifying and outputting the IF signal. The IF signal outputted from the frequency conversion part 1 passes through the IF tuning circuit 2 and is inputted to the intermediate frequency amplifier 3. Then, it is amplified and outputted in the intermediate frequency amplifier 3. The tuning frequency of the IF tuning circuit 2 is changed to be higher with the rise of a peripheral temperature.  Thus, a difference between the values of the tuning frequency and the video intermediate frequency is reduced and the attenuation of the level of the video intermediate frequency can be reduced.

Title: Control system of multiple pulse inverter
Inventor: SUGAYA TADASHI
IPC: H02M7/48
Filed: 1978-06-20
Abstract: PURPOSE: To reliably control a multiple pulse inverter, by obtaining stable alternating current output by comparing a main triangular wave with frequency double as many as output alternating current frequency and a by-triangular wave with frequency integral-fold as many as the main triangular wave.  
     CONSTITUTION: Main triangular wave voltage Wt1 with frequency double as many as the frequency of output alternating current and by-triangular wave voltage Wt2 with frequency integral-fold as many as the frequency of the main triangular wave voltage are generated. The crest value P of the by-triangular wave Wt2 is made to be value corresponding to the ratio of each instantaneous value of the main triangular wave Wt1 at the same point of time as each crest value P and output alternating current waves. The output waves Wt1 and Wt2 are compared by means of a comparator, and pulse output Wp with pulse width corresponding to the difference of both is obtained. Alternating current output voltage is gained by extracting pulse output through a smoothing circuit. Thus, positive and stable action is secured while alternating current output, which higher harmonic content is little, can be acquired.

IPC: H04L12/28
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To make a fault recovery by independent dispersion without requiring the centralized management of a network management system in case of a line fault. SOLUTION: Of a switch s1, a PVC control part informed of fault information from a line correspondence part having detected a fault finds a connection- destination switch s2 of the faulty link from adjacent switch connection information for re-linking PVC on the faulty link and makes use of the routing function of SVC for searching for a detour route to the switch s2. The PVC control part of the switch s1 requests an SVC control part to set SVC, and when a connection with the opposite switch s2 is completed by a SVC function, this PVC re-links a connection on the faulty link to the connection where the connection is completed. The switch s1 sends information on the connection completion to the opposite switch s2 after the connection is completed.  The opposite switch s2 having received the connection completion information makes a connection on the faulty link by the PVC by re-linking it to the connection where the connection is completed.
