Filed: 1991-05-23
Abstract: PURPOSE:To reduce an extending amount of solder due to leads of an IC package and to suppress generation of a bridge at the time of mainly placing the package by adding devising of a pad to be formed on a printed circuit board. CONSTITUTION:Wiring conductors are formed fixedly on a surface of an insulating board 1 based on a pattern design, and a pad A1 for placing electronic components is formed partly on the conductors. Many small protrusions 2 are formed on the surface of the pad A1 by suitable means such as adhering, soldering, etc. When an IC package P is placed on the pad A1, pressing amount of cream solder 3 by the soldered part 4a of a lead 4 is reduced in the amount corresponding to the height of the protrusions 2. Accordingly, the extending amount of the solder 3 is reduced, a bridge generated between adjacent leads can be suppressed.

Filed: 1993-06-22
Abstract: PURPOSE:To restrain the generation of a parsitic capacitance between a floating gate electrode for an output signal and a precharge electrode, by setting transfer start timing later than reset operation start timing by reset pulse. CONSTITUTION:After signal charge (e) transferred from a charge transferring part 3 is led out as a voltage signal, a control pulse(CP) Pg' is applied.

The cacao beans are pref. flavor beans reduced in mixed tastes and sour taste and pref. produced in Ecuador. The size of the cacao beans is pref. within the range of 3 to 5 meshes. The pressure after the pressure- and heat-pressure treatment is ordinarily returned to normal pressures, however, it is pref. put under a depressurized state when a cacao nib-containing chocolate or cacao nib-containing various foods are produced. The rotating process is pref. conducted by heat-treatment for 30 min. at 130 deg.C.

Title: Pulse circuit
Inventor: MATSUZAWA AKIRA
IPC: H03K17/60
Filed: 1983-08-17
Abstract: PURPOSE:To generate a pulse having excellent settling characteristics and accurate timing by inserting a resistor between a couple of output terminals outputting complementary pulses to each other to suppress the ringing at the differential mode. CONSTITUTION:The pulse circuit consists of an operating power supply 1, pulse sources 2A, 2B being in a complementary relation, transistors (TRs) 3A, 3B constituting a couple of emitter follower circuits, current sources 4A, 4B and logical circuits 8A, 8B constituting a load circuit, and the resistor 9 is inserted between the emitters of the TRs 3A, 3B. Although ringing occurs in the emitter output of the TRs 3A, 3B, since the mode of the ringing is in-phase, the ringings are cancelled by a differential output and a pulse without ringing is obtained. This is because the impedance of the differential mode is made lower than that of the common mode at the mutual output terminals by inserting the resistor 9.

Abstract: PURPOSE:To decrease parasitic capacitance and eliminate backgate effect in order to make the characteristics of a switched capacitor integrator approach to ideal ones, by a method wherein a switching transistor of the integrator is constituted on  a field insulating layer, with a polycrystalline Si layer used as a channel part. CONSTITUTION:In an integrator comprising transistors 1, 2 switched by means of clock signals, a feedback capacitor CF and an operational amplifier 3, a transistor 36 with polycrystalline Si as a channel is employed for switching. The transistor 36 is formed in the process for manufacturing a capacitor 37 and an ordinary. FET37 by means of the double layer polycrystalline Si technique. In other words, a channel part 28, a source and drain 26, 27 are formed in the first layer polycrystaline Si16 on a field film by using a gate 23 of the second layer polycrystalline Si as a mask. Thereby, because the junction capacitance with the substrate is eliminated, parasitic capacitance Cp can be decreased, so that capacitance ratio CI/CF can be set accurately. In addition, because the channel part 28 is floating, backgate effect can be eliminated, so that the dynamic range can be widened.
