Title: Acoustic wave device
Inventor: ISHIGAKI MASAHARU
IPC: H03H3/08
Filed: 1981-08-17
Abstract: PURPOSE:To remarkably suppress an end face reflection signal of an acoustic wave, by shifting a position of a propagation path end part, by >=1 stage by width of lambda/4XN(N=1,3,5-, and lambda denotes the wavelength of the acoustic wave), and also setting the overall length of the propagation path end part to half of the whole. CONSTITUTION:An electric signal is converted to an acoustic wave by the first reedlike electrode 2 or 3, and the surface acoustic wave is converted to the electric signal again by the second bamboo blind-like electrode 3 or 2. A position of a propagation path end part of the acoustic wave is formed by shifting at least 1 stage by width of lambda/4XN (N=1,3,5-, and lambda denotes the wavelength of the acoustic wave), and the overall length of the propagation path end part which has been shifted and formed is set to 1/2 of the whole. When each half of the propagation path end part for reflecting the acoustic wave is shifted by lambda/4X N from each other, reflected waves from the respective end parts negate each phase, no reflection signal appears in the second reedlike electrode, and a satisfactory frequency characteristic of only a main signal can be obtained.

IPC: H01L29/73
Filed: 1993-04-30
Abstract: PURPOSE:To effectively avoid the inversion phenomenon of a base region by the small number of treatment processes as compared with conventional cases by a method wherein, when a base diffused layer is formed, ions are implanted simultaneously, via an oxide film, into epitaxial layer situated in the circumference and also its impurity concentration is increased. CONSTITUTION:An epitaxial layer 4 of a first conductivity type is grown on a substrate, and a diffused region 5 of a second conductivity type is formed in the epitaxial layer 4 in the vertical direction. When a bipolar transistor is manufactured in this manner, the thickness of a partial region in an oxide film covering the epitaxial layer 4 out of an oxide film 6 formed so as to cover the surface of the epitaxial layer 4 and of the diffused region 5 is made a little thin as compared with the thickness of the oxide film covering the difused region 5. Then, ions of the first conductivity type are implanted into the lower part of the region in which the film thickness of the oxide film 6 is comparatively thin, a base diffused layer 9 is generated, and also the impurity concentration on the surface of the epitaxial layer 4 situated in the circumference of the base diffused layer 6 is increased.

Filed: 1979-10-05
Abstract: PURPOSE: To make it possible to perform the stable control by use of a smaller transformer, by controlling the maximum value of pulse width by which the switching circuit is controlled, according to magnitude of the DC input voltage.  
     CONSTITUTION: An output pulse PW of the pulse width control circuit 3 takes AND with an output pulse PD of the dead time 9' by which an output pulse is changed according to the input voltage E i , by the AND circuit 10, and the circuit 9' and the circuit 3 are triggered by the same oscillator 8 and are snhchronized. The characteristic of the circuit 9' is as a curve (b) shown in the figure, and in case the electric power source device is in a stable state, it does not become a hitch for stabilizing an output since its pulse width is a little wider than that of a pulse PW for stabilizing an output, which is shown by a curve (a). Since the output terminals 2, 2' are shorted, however, the result becomes EO=0, and when a pulse PW from the circuit 3 is maximum, the switching control pulse width PS is limited since width of a pulse PD from the circuit 9' is small, and saturation of the transformer can be prevented.

Abstract: PURPOSE:To obtain an electrostatic charge controller wide in an allowable addition range, good in stability of charge on toner particles, small in repeated uses, and good in dispersion stability and fixablility by incorporating a specified compd. CONSTITUTION:The compd. to be added is represented by formula I or II in which R1, R2 are each H, 1-22C alkyl (optionally substd. by 1-10C alkyl or dialkyl amino, alkyloxy, or alkylthio), aryl (optionally substd. by 1-10C alkyl, aryl, dialkylamino, alkyloxy, alkylthio, chloro, bromo, cyano, nitro, or hydroxy), aralkyl, 1-22C acyl, alkyl- or aryl-sulfonyl, alkyl- or aryl- phosphonyl; R<1> and R<2> may be same or different; A is 1-10C optionally substd. alkylene; and X is H or a mono- - tetra-valent metal or quaternary ammonium ion. Such a compd. is enhanced in solubility in fat, and promoted for dissolution in a carrier soln. by substitution of R<1>, R<2>. Since N capable of coordinating cations is located in the favorable position of the molecule, ionization is promoted, and the ions are solubilized stably in the carrier soln. by the effect of R<1> and R<2>. Toner partticles are charged negatively by adsorption or the like of the negative counterparts of the ions relatively small in solubility. When a polymer having especially amino groups are introduced, the cations are selectively adsorbed, and the toner particles are charged positively. Undesirable dissociation is restrained in the carrier soln. As a result, the obtained image is stable in a charge amt. in a wide range, good in each of storage stability, durability, dispersion stability, fixability, resolution, etc., and superior in gradation, etc.

Consequently, average value of unnecessary signals outputted from the synchronous detector 9 can be reduced extremely when a ramp signal Sr is mixed with an input to the synchronous detector 9. According to the arrangement, detection error of input angular speed can be reduced when the ramp frequency fr=1/4nτ.
