摘要:
A light source has a transparent substrate, a fixed substrate disposed in facing relation to the transparent substrate, and a plurality of electron emitters disposed on a principal surface of the fixed substrate. A light reflecting film is disposed on a portion of the principal surface of the fixed substrate which is free of the electron emitters. An anode electrode in the form of a transparent electrode is disposed on a substantially entire reverse side of the transparent substrate. Phosphor layers are disposed on the anode electrode at respective positions facing the electron emitters.

An electron-emitting apparatus includes an electron-emitting element having a lower electrode, an emitter section having a dielectric material, and a plurality of upper electrodes having micro through holes, and a drive voltage applying circuit having a circuit for applying a drive voltage Vin between the lower electrode and the upper electrode. The drive voltage applying circuit applies a drive voltage between the lower electrode and the upper electrode to set an element voltage Vka, which is a potential of the upper electrode relative to a potential of the lower electrode, at a negative voltage for a charge accumulation period Td so as to accumulate electrons in the emitter section, and to set the element voltage Vka at a predetermined positive voltage for an electron emission period Th so as to emit electrons from the emitter section. Further, the drive voltage applying circuit stepwise increases the positive voltage for the electron emission period Th and separately emits the electrons accumulated in the emitter section a plurality of times.

There are provided a waveform observing apparatus and the system thereof in which, when a removable storage medium is inserted into the waveform observing apparatus to capture a copy of measured data, a difference copy is made while including the latest measured data collected by the waveform observing apparatus at the time, sixteenth and seventeenth measured data temporarily stored in a buffer memory are filed and stored in the state of being housed in a fourth measured data file, into a body memory. Copies of a third measured data file including part of the difference copy and a new fourth measured data file are written into the USB memory. When the USB memory is inserted into a personal computer, a hard disk of the personal computer comes into a state where its third measured data file is overwritten and stored and the fourth measured data file is newly stored.

A connector housing with a mat seal, includes a connector housing a mat seal. At an outer surface of a rear wall of the connector housing, a plurality of passages for a silicone gum forming material are provided outside an area where a plurality of terminal insertion holes are formed. On the outer surface of the rear wall and outside the passages, an annular rib is protruded and surrounds an area inside the annular rib. The mat seal is molded by using the area inside the annular rib as a reservoir space in which the silicone gum forming material overflowing from the seal forming cavity is retained, and using at least one of the passages as a passage for a gate through which the silicone gum forming material is injected into the seal forming cavity, and the other of the passages as passages for overflow.

There is provided a method for testing a piezoelectric/electrostrictive actuator, wherein the displacement of a piezoelectric/electrostrictive actuator is estimated on the basis of the relations between one or more frequency characteristic values selected from the group consisting of the heights and areas of the peaks of the resonance waveforms and the difference of the maximum and minimum of the first order or first to higher orders of the resonance frequency characteristic values of the piezoelectric/electrostrictive actuator and the k-th order (k=1 to 4) of the first or first to higher orders of resonance frequencies. According to this piezoelectric/electrostrictive actuator testing method, a piezoelectric/electrostrictive actuator can be tested with high precision without actually driving the same as a product and without being accompanied by any disassembly/breakage.

To ensure that an electric power cable and a signal cable are laid easily over short distances while suppressing an effect of electromagnetic wave noise on the signal cable, an electric power cable is laid along a route that passes through only a right outside space in a lower position than an upper end of a right vertical plate, while a signal cable is laid along a bypass route that extends from a generator motor in a lower position than the upper end of the right vertical plate, passes through a rear portion cable insertion hole into an intermediate space between the right vertical plate and a left vertical plate, and returns to the right outside space from the intermediate space through a front portion cable insertion hole.

摘要:
A light source has a transparent substrate, a fixed substrate disposed in facing relation to the transparent substrate, at least one electron emitter disposed on the fixed substrate, a phosphor layer disposed on a surface of the transparent substrate which confronts the fixed substrate, and a trajectory deflector for deflecting the trajectory of a pulsed electron flow intermittently emitted from the electron emitter. The pulsed electron flow is deflected by the trajectory deflector to two-dimensionally scan a position of the phosphor layer which is irradiated with the pulsed electron flow for thereby spreading the pulsed electron flow.
