Title: Cross recessed screw and screwdriver bit
Inventor: TOYOOKA TOSHIMASA
IPC: B25B15/00
Filed: 2001-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a cross recessed screw easily tightened to a screw fastening torque set beforehand and used even for a relatively shallow driving recess. SOLUTION: This engagement groove 11 forms a driving recess 10 with which a screwdriver bit 20 engages. An upright fitting surface 15 is formed along an axial line between an engagement groove 11 and another engagement groove 11 provided adjacently forward in screw fastening direction. An upright side surface 13 continuing from the upright fitting surface 15 and standing upright from a bottom surface 12 is formed. A first passive part is composed of the upright side surface 13 and the upright fitting surface 15, and a second receiving part of same structure is provided in a side opposing to the first passive part. Since the cross-recessed screw has this structure, come-out phenomena do not occur often at completion of screw fastening work. Consequently, the screw fastening torque set beforehand is accurately provided.  Since a fitting recess is formed relatively shallow, thickness of a head part is less than that of an ordinary head.

Title: Chopper comparator
Inventor: MORIMOTO HARUAKI
IPC: H03K5/24
Filed: 2001-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a chopper comparator with little offset errors. SOLUTION: When a clock signal CK is 'L', an input changeover switch 2 is switched to an input voltage Vi side and PMOSs 6 and 7 are also turned on to set the electric potential of an internal node NA in a threshold voltage Vt of an inverter 4. If the clock signal CK changes to 'H', the PMOSs 7 and 8 are turned off and on, respectively, the electric potential of the internal node NA is fluctuated by parasitic capacitance between the source and the substrate of the PMOS 6. However, the electric potential of the internal node NA returns to the threshold voltage Vt because the PMOS 6 is kept on by a delay circuit 10. Thereafter, the PMOS 6 is turned off by a delay clock signal DCK, and the input changeover switch 2 is also switched to a reference voltage Vr side. Thus, the inverter 4 outputs a signal of a comparison result with little offset errors.
