Title: Laminate type displacement element
Inventor: SADAMURA SHIGERU
IPC: H01L41/083
Filed: 1988-07-26
Abstract: PURPOSE:To greatly improve the efficiency of piezoelectric conversion and the life as well as completely prevent any deformation from being increased and any crack from being produced owing to stress concentration by providing a buffer part between a non-displacement part formed in the vicinity of the side of a laminate and a displacement part formed within the laminate such that the displacement of the buffer part is specified. CONSTITUTION:A silver-palladium paste comprising an internal electrode is screen-printed on the entire surface of a sheeted material. A partial electrode 21 as part of the internal electrode is also printed upon the printing of the internal electrode. The thin sheets 1 are pressed and laminated, cut into a laminate of a predetermined size and shape, and sintered. Thereafter, the laminate is applied with screen printing of a silver paste used for external electrodes 3a, 3b, forming a laminate type displacement element. The buffer part C is formed such that the existence ratio of the internal electrode 2a (2b) on the thin sheet 1 is increased monotonously from 0% at a non-displacement part b to 100% at a displacement part 9.

Title: Production of 2,3-dimethyl-2-butene
Inventor: NOMURA KOTOHIRO
IPC: B01J31/24
Filed: 1993-07-28
Abstract: PURPOSE:To efficiently produce 2,3-dimethyl-2-butene important as a key intermediate for agrichemicals, medicines, perfumes and cosmetics, etc., from 2,3- dimethyl-1-butene using sulfuric acid or a sulfonic acid compound as isomerization catalyst. CONSTITUTION:The 2,3-dimethyl-2-butene can be obtained by isomerizing 2,3- dimethyl-1-butene at -30 to 100 deg.C (pref. 0 to 60 deg.C) using sulfuric acid or a sulfonic acid compound (esp. pref. methanesulfonic acid) at 0.01-5.0 (pref. 0.05-1.5)wt.% based on the 2,3-dimethyl-1-butene. The isomerization can be accomplished for the 2,3-dimethyl-1-butene produced by dimerizing propene using a dimerization catalyst such as a nickel compound-contg. catalyst, without the need for eliminating the catalyst. In this case, if the isomerization is conducted after deactivating the catalyst, the recovery of the 2,3-dimethylbutenes can be improved.

Title: Formation of phase shift mask
Inventor: IMAI TADAYOSHI
IPC: G03F1/30
Filed: 1990-07-13
Abstract: PURPOSE:To form the good and effective phase shift mask by forming multiple kinds of different metals in multiple layers as light shieldable metallic thin films on a shifter film and successively patterning and forming the respective light shieldable metallic thin films and the shifter film. CONSTITUTION:After multiple kinds of the different metals are formed in multiple layers as the light shieldable thin metallic films 4, 5 on the shifter film 3, the respective light shieldable thin metallic films 4, 5 and the shifter film 3 are successively patterned and formed. A Cr film which is the light shieldable thin metallic film 4 of the lower layer is formed on the lower side of an MoSi2 film which is the light shieldable thin metallic film 5 of the upper layer and, therefore, the Cr film of the lower layer plays the role as the protective film of an SiO2 film which is the shifter film 3 in this case. The possibility that the SiO2 film is overetched is eliminated. The mask is formed while the uniformity of the thickness of the shifter film 3 at the time of sputtering is maintained.

Title: Picture encoding/decoding system
Inventor: KASA HIROSHI
IPC: H04N19/61
Filed: 1988-07-26
Abstract: PURPOSE:To improve the reproducibility of an edge part with small bits by approximating an input picture signal with a known function, encoding informa tion to specify the function, encoding the error part of the input picture signal, obtaining respective encoded outputs, and transmitting the two encoded outputs. CONSTITUTION:A curve approximate picture encoder 12 approximates, for example, luminance change in a horizontal direction by a simple geometrical curve such as an isolated wave, a rectangular wave and a triangular wave, generates a curve approximate picture signal, and outputs it as a first encoded output. The first encoded output is decoded in a curve approximate picture decoder 13, and the curve approximate picture signal is generated. In addition, a subtracter 14 subtracts the said curve approximate picture signal from the input picture signal inserted through an input terminal 11, and outputs an error picture signal. An error picture encoder 15 can efficiently obtain a second encod ed output at a high quality by applying a conventionally used encoding method to the error picture signal.

Title: Semiconductor storage circuit
Inventor: ISHII YASUHIRO
IPC: H03K3/284
Filed: 1986-08-08
Abstract: PURPOSE:To prevent a write error by detecting a write signal inputted from the external and generating another write signal which is not related to the detected write signal and has a certain pulse width. CONSTITUTION:When the write signal is inputted, transistors TRS Q1 and Q2 are turned off. Since a TR Q4 is turned on therefore, a trigger pulse is transmitted through a capacitor C 1. Then a TR Q5 is turned on. Meanwhile, a TR Q7 is turned on and the voltage at a nodal point (f) is reduced because a TR Q6 is turned off. The voltage at a nodal point (d) gradually rises in accordance with the time constant determined by RBXC2, and the TR Q6 is switched to the turning-on state from the turning-off state when this voltage exceeds a voltage vref2. Then, the voltage at the nodal point (f) rises. Thus, the pulse width of the write signal is always set to a certain value independently of the pulse width of the write signal inputted from the external.
