Title: Printer device
Inventor: HISAMATSU KENICHI
IPC: G06K15/00
Filed: 1988-07-28
Abstract: PURPOSE:To enable printing without any lowering in accuracy of paper feeding at the time of printing through arbitrarily designating a line feed pitch by providing a means for reading line feeding speed data from a storage means, and a means for controlling the driving of a paper feeding mechanism. CONSTITUTION:At the time of paper feeding, a controlling means 21 compares a line feed pitch designated by a host device 29 with a reference line feed pitch stored in a memory 22. The controlling part 21 reads first line feeding speed data or second line feeding speed data from the memory 22 according as the designated line feed pitch is smaller or greater than the reference line feed pitch, and gives the read line feeding speed data to a driving circuit 25 for a cut paper feeding motor. The driving circuit 25 drives cut-paper rollers 14a, 14b based on the line feeding speed data. A line feeding speed defined by the second line feeding speed data is set to be slower than that defined by the first line feeding speed data, so that when a line feed pitch greater than the reference pitch is designated, a paper 13 is fed at a lower velocity as compared with that in the case where a line feed pitch smaller than the reference pitch is designated. Thus, the line feeding speed is lowered, and a deflection of the paper 13 can be reduced by a restoring force of the paper 13 accordingly.

Title: Method for mounting bare ic chip
Inventor: ENDO YASUHIRO
IPC: H05K3/32
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To make simple the manufacturing process of mechanical equipment or a wiring board constituted by mounting a bare IC chip on a circuit, by emitting electromagnetic waves upon the bare IC chip from the side opposite to the arranging side of the chip while the chip is press-contacted with a base material. SOLUTION: A circuit 1 is formed on a base material 2, and an insulating adhering section 5 for the terminals 3 of a bare IC chip 3 is formed by printing an insulating adhesive substance B. Then terminal adhering sections 6 are formed in the circuit 1 so that the sections 6 may necessarily come into contact with the terminals 4 of the chip 3, by printing a conductive adhesive substance A until thicknesses of the sections 6 become thicker than that of the section 5. Thereafter, the chip 3 is placed on the base material 2 by aligning the chip 3 with the insulating adhering section 4 and terminal adhering sections 6 and press-contacted with the material 2. While the chip 3 is press-contacted with the material 3, electromagnetic waves are emitted upon the chip 3 from the side opposite to the arranging side of the chip 3. Thus, the chi 3 is mounted on the circuit 1.

Title: Picture memory
Inventor: SAKAI MASAKI
IPC: G06T1/60
Filed: 1988-07-28
Abstract: PURPOSE:To properly store the pictures regardless of the aspect ratio of the input information by providing an input picture information memory and a memory control means which stores the written information so as to be analo gous to the aspect ratio of the input information. CONSTITUTION:A control means transfers only the valid areas of picture information 9420R-9420B to the FIFO memories 4050R-4050B and at the same time applies the trimming and variable power processes to those valid areas. The valid area set in the main scan direction of a pointed area is first written into a RAM 4212 via a CPU bus. Then a selector 4213 is controlled so that '0' and '1' are written into the valid and invalid areas of an area pointed by the RAM 4212 respectively. Then a counter 4214 is validated by the selector 4213, and a signal 9452 and a WE signal 9100 synchronized with a CLK 9453 are transmitted to the RAM 4212 and a latch 4211. Then only the valid areas of the pictures are written into the memories 4050R-4050B. These written information are outputted as the signal 9090R-9090B from an address 0 with delay equal to the single main scan and synchronously with the signal 9452. In such a constitution, the pictures are stored despite the different aspect ratios of the input information.

Title: Etching method for rear of semiconductor wafer
Inventor: HORIO TAKUJI
IPC: H01L21/3065
Filed: 1990-07-17
Abstract: PURPOSE:To obtain the etching method, of the rear of a semiconductor wafer, capable of forming the rear of the wafer, in a short time which does not contain a crushed layer and whose close contact property with a metal film is good by providing the following: a process to remove a reaction product which has adhered to the inside of an etching chamber as a first step; and a process to remove an oxide layer formed on the rear of the wafer and to etch the rear of the wafer as a second step. CONSTITUTION:When the rear is etched in order to remove a crushed layer 13 (including a crack 13), an O2 ashing operation is executed as a first step and a deposit produced inside an etching chamber at the etching operation of Si on the rear of a wafer is removed. However, by the O2 ashing operation, an oxide layer 14 is formed on the rear of the silicon wafer 11. Then, the oxide layer 14 formed on the rear of the silicon wafer 11 at the first step is removed, and the Si (the rear of the wafer) is etched as a second step. At the second step, the oxide layer 14 and the crushed layer 12 (including the crack 13) are removed, and the good-quality rear of the wafer is revealed. Consequently, even when a metal film 15 is applied to the rear of the silicon wafer 11 at a next process, it is not stripped.

Title: Isolated transmission line and manufacture thereof
Inventor: DEIBUITSUDO BII TATSUKAAMAN
IPC: H01L21/3205
Filed: 1989-07-19
Abstract: PURPOSE: To improve electric performance of a microstrip transmission line by forming one microstrip transmission line at least on a dielectric layer, removing the dielectric layer from the outside area of each line, and forming an independent line supported by the post of dielectric materials under respective lines. CONSTITUTION: A separated metal microstrip line 20 exists only at a post 22 of dielectric materials between a metal wire and a metal ground surface 24. The vertical dielectric post 22 is separated by a gap or an opening area 26 extending downward to the ground surface 24 inside a space around the metal wire 20, or the gap is fixed. Therefore, the dielectric material existing between the metal wire 20 and the ground surface 24 is either only a vertical wall having substantially the same width as the metal wire 20 or only the post 22. The area which is higher than the ground surface 24, namely, the gap 26 is filled with air of dielectric constant '1'. Thus, the composite dielectric constant or the average dielectric constant between the metal wire 20 and the ground surface 24 is reduced substantially and electric characteristics in transmission line structure 26 can be improved.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of switching elements and provide current waveform control for respective AC phases, by using a three-phase full-bridge circuit consisting of an arm constituted of a serial circuit of a switch and a capacitor.
