Title: Document insertion and control method, documents used therefor, and document insertion and controlling system
Inventor: TSURUKAWA SOICHI
IPC: G01S13/74
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To sort a product in which no documents are correctly inserted by transmitting the electromagnetic wave of the natural resonance frequency to a product packaging, and recognizing the presence/absence of reception of the responsive reflected wave from a resonance label to reflect the electromagnetic wave of the specified frequency and the frequency of the reflected wave to surely judge the presence/absence of a document in the product packaging and the kind of the document. SOLUTION: A product packaging 10 is an article whose inside is not directly observed in a general condition, and a document 12 such as a prescription is contained inside. When the electromagnetic wave of the natural resonance frequency is transmitted to the product packaging 10 from a scanner 21 for identification through an antenna 22, the reflected electromagnetic wave is transmitted from a resonance label 11 attached to the document 12, and received by a receiver 23. When no reflected electromagnetic wave is received, it means that no specified document 12 is inserted, and the kind of the document 12 can be judged by the frequency of the reflected electromagnetic wave. A plurality of kinds of documents 12 can be inserted in the product packaging 10, and resonance labels of different natural resonance frequency can be contained.

Title: Data generating frequency analyzer
Inventor: FUIRITSUPU ESU KUROSUBII
IPC: G01R19/175
Filed: 1989-12-26
Abstract: PURPOSE:To efficiently count the number of the generating times of many different digital patterns at a high speed by designating the RAM array of an address corresponding to a generating pattern and using the RAM of the designated address as a linear feedback shift register array. CONSTITUTION:Data to be analyzed is supplied to the address input terminal of the RAM array 50 and one among the linear feedback shift register arrays is selected. The selected linear feedback shift register increases (or decreases) the pseudo random counting by a 'data valid' signal DV and a 'code valid' signal CV which is obtained by delaying the signal DV by a delay means 12. When an analysis period terminals, respective pseudo random codes of the linear feedback shift register are converted into a meaningful count value by using a conversion means 56. Thus, the number of the generating times of the patterns is learnt by reading the content of the RAM array 50 of the address corresponding to respective digital patterns.

Title: Method for heating and joining piezoelectric body and substrate
Inventor: TAKADA HIDEKAZU
IPC: H01L41/22
Filed: 1992-11-24
Abstract: PURPOSE:To provide a method for heating and joining a piezoelectric body and a substrate without any warpage and crack and characteristic deterioration in a joint body even if they are cooled to normal temperatures after they are heated and joined. CONSTITUTION:The temperature dependency of average expansion coefficients of a piezoelectric body (PZT (1) and PZT (2)) which is heated and joined to Si substrate and the Si substrate from normal temperatures is obtained. In the case of the piezoelectric body PZT (1), the average expansion coefficient from the normal temperatures matches that of the Si substrate from the normal temperatures near 500 deg.C. On the other hand, in the case of the piezoelectric body PZT (2), it approaches the average expansion coefficient of the Si substrate from the normal temperatures near 300 deg.C. When the piezoelectric body PZT (1) is heated and joined to the Si substrate near 500 deg.C and the piezoelectric body PZT (2) is heated and joined near 300 deg.C, the heat shrinkable deformation of the piezoelectric body and that of the Si substrate are nearly equal when they are cooled to the normal temperatures thus preventing warpage and crack of a joined body and deterioration of characteristics of the piezoelectric body.

Filed: 1987-12-28
Abstract: PURPOSE: To provide a transistor storage cell which is highly immune to noises, without needing an epitaxial layer by facing the surface of a polycrystalline Si core formed in a trench, perpendicular to a substrate surface in a p-type region formed round the trench through a dielectric layer. CONSTITUTION: A capacitor is formed in a cylindrical trench 11 approximately vertical to the plane of a semiconductor substrate surface. The vapor phase diffusion is applied to form a p+-region 13 contg. B at a high concn. in the trench 11.

The core 14 is isolated from the region 13 through a thin dielectric layer 15 of Si dioxide or mixture of Si nitride and Si dioxide. Charge storage occurs in the core 14 at a deep part 19 of the trench. This structure eliminates need for the use of an epitaxial layer and reduces the cost of a MOS semiconductor device, using the trench-type storage capacitor.

Inventor: YOSHIDA HIROICHI
IPC: G09G5/22
Filed: 1993-12-28
Abstract: PURPOSE:To provide a character output device capable of outputting a sentence matching with need at high speed. CONSTITUTION:When no key input exists in the character output device (NO in S119), whether or not an advance development mode is set is judged (S120). When the mode is set, format information is stored in a document buffer based on a size and a format of an inputted character, and an outline font is developed to a dot font according to respective modes based on the information to be stored in a cache buffer (YES in S120, S121-S124). That is continued while no key input exists (NO in S119, S120-S124). Since the outline font is developed to the dot font until an instruction of print is issued based on really used character size and type face to be stored in the cache buffer, the character really used by a user is developed beforehand and sufficiently.
