Title: Picture reader
Inventor: SUZUKI KENJI
IPC: G03G15/22
Filed: 1985-02-21
Abstract: PURPOSE:To obtain a picture reader with a simple construction and low cost by controlling independently the taking out of a signal from each of a store-type image sensor and executing a signal processing by one set of a signal processing circuit. CONSTITUTION:A MOS type image sensor 95 executes alternately store and read out with a prescribed cycle. When a store start signal is outputted from a controller 52, on the trailing edge of a vertical synchronizing signal after the termination of a normal store, a flip-flop 97 is set at a synchronized timing and along with this, a timer 70 starts to operate. Because an And gate 98 is closed by the setting of the flip-flop 97, the input of a master clock to a driver 96 is ceased. In this case, the taking out of a signal is tentatively interrupted. Even in this case, the store is continued because a blue color light which transmits a liquid crystal 100 in open state and a blue color filter 101 is inputted to a photoelectric transfer part 95a. Thereby, only one signal processing circuit is needed and cost is reduced remarkably.

IPC: H01L21/3065
Filed: 1991-01-31
Abstract: PURPOSE:To completely eliminate residual chlorine after the patterning of an Al based multilayered film having a barrier metal structure, and prevent after-corrosion. CONSTITUTION:A multilayered film 5 wherein a TiW layer 2, an Al-1% Si layer 3 and an amorphous silicon layer (antireflection film) 4 are laminated is etched by using an SOG pattern 6 as a mask and S2Cl2 gas. Since organic resist material is not used for a mask, residual chlorine is not taken in the inside of the mask itself or a CClX based side wall protecting film. Further an S-based side wall protecting film 7 is formed on the side wall part of a wiring pattern 5a, and high anisotropy is achieved. In other inventions, the TiW layer is etched by using S2F2 gas after etching is performed as far as the Al-1% Si layer by using chlorine based gas. In the latter half process, the residual chlorine is substituted by fluorine, and further anisotropic working is performed on account of deposition of S.

Abstract: PURPOSE:To decrease the points of electrical connection and thus increase the reliability of a circuit block of an electronic watch with a small and thin structure, by unifying a quartz oscillator and an IC chip. CONSTITUTION:The electrode wiring 13 is formed by attaching a conductive material to the quartz oscillator 1 by a vapor deposition or sputtering method, and the metal 11 is evaporated to extract the electrode of the IC chip 12.

Title: Twisting mode piezoelectric ceramic transformer
Inventor: INOUE TAKESHI
IPC: H02M5/04
Filed: 1981-03-06
Abstract: PURPOSE:To reduce the size of a transformer by utilizing twisting vibration by bonding two piezoelectric ceramic plates longitudinally polarized at the sides parallel to the polarizing direction so that the polarizing directions become oppositely against each other. CONSTITUTION:Longitudinally polarized piezoelectric porcelain plates 20, 21 are bonded at the sides parallel to the polarizing direction so that the polarizing directions become oppositely to each other. Drive electrodes 22, 23' and output electrodes 24, 24' are formed on the upper and lower surfaces of the respective plates 20, 21. When they are excited from the drive terminals 25, 25', opposite slipping vibrations are excited in the plates 20, 21 due to the reverse polarizing directions, and since they are rigidly bonded with an adhesive 22, the slipping vibration is converted into twisting vibtation. Since the elastic stiffness of the twisting vibration is smaller than that of the longitudinal vibration, a small size piezoelectric ceramic transformer can be obtained.

Abstract: PURPOSE:To visually display function patterns obtained through various functional calculations made by using a functional electronic aclculator, by installing a function recognizing mode setting means which is to be used for performing graphic representing, etc., of functions. CONSTITUTION:When a SIN key Si is pressed, a signal passes through a data bus DH and is planted into an I/O buffer R in a CPU. When a control arithmetic section CAL detects that the SIN key is pressed, it accesses an SIN routine from a program in a memory section RM in the CPU. When a graphic printing key is pressed, the control arithmetic section CAL detects this and accesses a graph printing routine in the SIN routine. The leading address in which the graphic pattern of the SIN curve is planted, is assigned to a fixed memory GROM from an address counter AC through an address bus AB. In this way, the data are DMA-transferred to a printer PR and the graphic pattern is printed.

Title: Tape cassette
Inventor: IWASAKI HIDEJI
IPC: G11B23/087
Filed: 1985-02-21
Abstract: PURPOSE:To prevent U-shaped casing of a cassette from moving rotationwise during the non-operation and assure a movement of rotation during the operation by having a configuration to allow an energized action point on the U-shaped casing-cover to generate the most energized state at around the cassette main unit centers. CONSTITUTION:Using two sheets of flat springs 7a and 7b as an energy-generating measure for U-shaped casing-cover 4, the flat spring 7a is situated at a front side from the flat spring 7b against a rotational movement branch axis 6. Since in the vicinity of action point P to be energized on the rotational movement branch axis 6, its flat spring 7a is formed so that its width is narrower than the flat spring 7b, the flat spring 7a allows an energy for the rotational movement branch axis 6 which is formed in a body U-shaped casing-cover 4 to be a maximum state at around a junction surface of upper and below half parts 2 and 3. And at a position where U-shaped casing-cover makes around 45 angles rotational movement, the flat spring 7a and 7b will transform as they give twists at an angles of only m, so that they will lighten an energy to effect on the action point P. Thus restraining the biggest energy, the flat springs allow the U-shaped casing-cover 4 which fits in the projection edge 18 on a cassette opening surface to move ahead and make it possible to increase an action energy which has an involvement relation release.
