Title: Method and apparatus for decreasing effect of sample-switch charge injection into plurality of series-connected sample-data comparators
Inventor: MAIKERU MAIIZU
IPC: H03K5/00
Filed: 1992-05-15
Abstract: PURPOSE: To provide a method and a device for reducing the influence of feed- back switch charge injection into the plural and serially-connected sample data comparators. CONSTITUTION: Current-programmable delay elements 82, 84 and 86 receive a supply voltage from a line 90 and receive a delay control signal from the line 94, which is from an EE programmable current source 92. The delay element 82 receives a feedback control signal T1 from the line 98, and first and second delay feedback switch control signals are generated in the lines 102 and 106. The line 102 is connected to the gate terminal 108 of an NMOS transistor 110 and, moreover, is connected to the terminal 32 of the NMOS transistor 30. The transistor 110 functions as a dummy device, and electric charge injection into a node E1 is reduced. The delay elements 84 and 86 also respectively respond to the received signals in the feedback switch control lines 114 and 130, so as to execute an operation in the same way as that of the delay element 82.

Title: Composite packing
Inventor: HIRAI MASANORI
IPC: F16J15/12
Filed: 1981-08-08
Abstract: PURPOSE:To heighten sealing stability of a composite packing by burying a form memory alloy as a core material in an elastic material en bloc. CONSTITUTION:A form memory alloy 1 is buried in a synthetic rubber 2 en bloc so as to form a composite packing 3. When the clamping temperature is lower than martensite transformation temperature of the form-memory alloy 1, the clamping pressure causes the form memory alloy 1 as well as the synthetic rubber 2 to be easily compressed and deformed. When the temperature of the packing 3 rises more than the martensite transformation temperature, the form memory alloy 1 is about to be restored to the initial state. Therefore, the synthetic rubber 2 receives a great working pressure as reaction force from the interior thereof toward a portion contacting a flange 4, so as to show sealing stability better than a single packing of a synthetic rubber.

Title: Carbon film resistor and film formation thereon
Inventor: TEZUKA KYOICHI
IPC: H01C7/00
Filed: 1987-05-21
Abstract: PURPOSE:To obtain a resistor having a low temperature coefficient and improved heat resistance, by forming a carbon coat film containing an extremely small amount of boron on an insulating substrate by means of the plasma CVD process using hydrogen carbide and diborane. CONSTITUTION:A carbon coat film containing an extremely small amount of boron is formed on an insulating substrate by means of the plasma CVD process using hydrogen carbide and diborane. More particularly, hydrogen carbide and a boron compound are introduced into a reaction vessel, in which they are heated to 600-1000 deg.C and plasma excited so that a carbonic coat film is formed on the insulating substrate disposed within the reaction vessel. Since the plasma CVD process can be carried out at a relatively low temperature, it is possible to decrease thermal damages, to prevent reaction with the substrate materials and to form a thin film on a non-heat-resisting substrate. Accordingly, the resistor is allowed to have a decreased temperature coefficient and improved heat resistance.

Title: Automatic focusing method
Inventor: HIDESHIMA TAKAHIRO
IPC: G03B21/11
Filed: 1986-06-02
Abstract: PURPOSE:To simplify an optical system by generating a focus signal based on the maximum value of the differential histogram of the output voltage of an image sensor and controlling the position of a projection lens. CONSTITUTION:A CPU 72 reads the output signal voltage (v) of a line sensor 56 successively by following up the scan of the sensor and calculates the absolute value of its time differential at the same time to store a pair of (v) and (ldv/dtl) in a RAM 76. This differential value is found as the difference of the successively read output signal voltage (v). The CPU 72 calculates the total S1 of the differential value to the constant value v1 of the output signal voltage (v) and finds the totals S2, S3... of the differential value when the output signal voltage (v) is varied to v2, v3..., thereby storing them in the RAM 76 successively. Then, the CPU 72 finds the maximum value S(MAX) among the totals S1, S2... and stores it as a focus signal F(alpha) at the current position X(alpha) of the projection lens. The CPU 72 moves the projection lens 20 by a specific quantity and performs similar operation repeatedly to obtain the position of the projection lens 20 where the focus signal F is maximum as a focusing position.

Abstract: PURPOSE:To avoid the competition of access, to omit a circuit for competition control and to miniaturize the device by shifting the timing of access to a memory. CONSTITUTION:When a synchronizing signal SA and data DA synchronous with that signal are sent from a transmission line A, a write control part 2 detects the timing of write to a memory 1 corresponding to the synchronizing signal SA and writes the data DA in the memory 1. On the other hand, an output request signal RS of data is inputted from a transmission line B, and a read control part 3 reads data DB from the memory 1 and outputs the data DB to the transmission line B corresponding to a synchronizing signal SB. When the data request signal RS comes from the transmission line, the read control part 3 performs the retiming of that signal corresponding to the synchronizing signal SA. The write control part 2 reads the data DB from the memory 1 at the timing not overlapped with the timing of performing access to the memory 1 and outputs those data to the transmission line B together with the synchronizing signal SB.
