Title: Automatic positioning device
Inventor: IIDA TAKAO
IPC: G05B19/27
Filed: 1979-07-24
Abstract: PURPOSE: To attain precise positioning easily by using a code plate with an array of a group of position codes and a group of light emission elements constituted so that a stop position code will be set, as to an automatic positioning device.  
     CONSTITUTION: A stop position number, when inputted, is converted into a binary signal, which is applied to a group of light emission elements; when it shows binary "1", one light emission element turns on and when binary "0", the other turns on. On code plate 13, position code groups C 1 WC 72  are arranged and position code Ci is provided with couples of small sections P 0 WP 6 . When the position code shows binary "0", one small sections is punched and when binary "0", the other is punched. When the stop position number coincides with position code Ci on code plate 13, the code plate cuts off light from the light emission element group and positioning is so carried out that a group of the light sensing elements will not detect the penetrating light. The abovementioned positioning system of simple constitution provides accurate positioning without using a stop-position-number momory unit and comparing circuit.

Title: Pll oscillator and piezo-oscillator
Inventor: KARASAWA HIDEO
IPC: H03L7/18
Filed: 1995-04-19
Abstract: PURPOSE:To provide a compact PLL oscillator which can output high frequency that is hardly outputted by a crystal oscillator serving as a clock source by selecting the dividing number of a programmable divider of a PLL circuit and outputting a prescribed frequency. CONSTITUTION:The signals received from a crystal vibrator 1 and its oscillation circuit 2 are divided by a reference divider 3 and inputted to a phase comparator 4 as the reference signals. The oscillation signal of a VCO 6 is divided by a feedback divider 9 and inputted to the comparator 4, and the voltage according to the phase difference between the oscillation signal and the reference signal is supplied to the VCO 6 via an LPF5. Thus the oscillation frequency is controlled. The oscillation signal of the VCO 6 is divided by an output divider 7 and outputted via an output buffer 8. The dividers 3, 9 and 7 are all programmable dividers and the dividing numbers or these dividers can be changed by rewriting the dividing number data M, N and X stored in a memory 11. Thus it is possible to obtain an inexpensive circuit that can easily set the frequency.

Title: Semiconductor memory device
Inventor: KATSUNO KUNIO
IPC: G11C17/00
Filed: 1984-05-11
Abstract: PURPOSE:To reduce a peak current at precharging and to suppress the fluctuation of a power supply volage by controlling the on-timing of two precharge transistors different in current abilities. CONSTITUTION:After the on-timing is controlled through control gates 25 and 26, a precharge transistor 5 of a small current ability is turned on earlier than a precharge transistor of a larger current ability. Consequently, after a digit line 8 for memory transistors 21 and 22, both of which are connected to a sensor amplifier 23, is precharged by the transistor 5, said line 8 is precharged by a transistor 24; therefore a small amount of a peak current for flowing at precharge is sufficient and the power supply voltage fluctuation can be suppressed. Accordingly the occurrence of malfunction caused by said fluctuation can be prevented.

Filed: 1983-05-30
Abstract: PURPOSE:To provide diversity of display by using a mixture composed of an oxidation type EC material and a redution type EC material having different coloring hues as an electrochromic (EC) materal, providing an insulating film in the region except the display pattern of a display electrode and providing a counter electrode in the position shaded by the same. CONSTITUTION:A mixture composed of an oxidation coloring type (O type) EC material and reduction coloring type (R type) EC material having coloring hues different from each other are used for the EC material to be used for an electrolyte 14. A display electrode 11 is provided on one transparent base plate 9 and an insulating film 13 is provided in the region except the pattern to be displayed on the electrode 11. A counter electrode 12 is formed in the position shaded by the film 13 when viewed from the base plate 9 side provided with the electrode 11. A voltage is impressed on the electrodes 11, 12 with the ECD of such constitution. When a positive voltage is impressed thereon, the O type EC material forms a display color and when a negative voltage is impressed thereon, the R type EC material forms a display color. The color formed on the electrode 12 in this stage does not exist in the display pattern region and is therefore not visually sensed. When the impressed voltage is made 0V, the display is erased. The diversity of the display is remarkably improved by using the plural EC materials.
