Title: Power-on reset circuit
Inventor: KOYAKE ISAO
IPC: G06F1/24
Filed: 1990-07-16
Abstract: PURPOSE:To reduce the influence of the voltage fluctuation by using an enhancement type MOSFET to form a differential amplifier and then biasing the substrate of a transistor TR to which the reference voltage is applied. CONSTITUTION:A reset circuit consists a voltage comparator 1 including a current source 2, a differential amplifier 3, and an output buffer 4. The source 2 consists of the TR 21 and 22 supplies the voltage of a fixed level to the gates of a TR 31 of the amplifier 3 and a TR 41 of the buffer 4 respectively. The amplifier 3 consists of the enhancement type MOSFET 31-35, and the substrate potentials of the TR 32 and the TR 33 are connected to a power supply Vdd and a source potential respectively. In other words, the substrate of the TR 32 is adversely biased. In such a constitution, the Vth never has a big fluctuation despite the variance of the bias value as long as the bias voltage Vbs is previously applied to a semiconductor substrate. Then the TR 32 which decides the reference voltage Vref' of the comparator 1 can have the stable Vth.

Title: Electrophotographic toner and its production
Inventor: NAKAYAMA KOJI
IPC: G03G9/087
Filed: 1994-07-19
Abstract: PURPOSE:To enable low temp. fixing, to avoid problems of the storage property for practical use, and to improve the fixing strength to a transfer paper by incorporating a specified binder resin, reactive monomers and a catalyst for radical polymn. CONSTITUTION:This toner contains at least a binder resin having unsatd. double bonds, a catalyst for radical polymn., reactive monomers and coloring agent. These mixed particles are subjected to heat treatment or mechanical impact force so that the toner particles are gradually hardened from the inside to the surface. In this case, the binder resin used has double bonds and various kinds of resins modified with unsatd. monomers such as unsatd. polyester resin can be used as the resin having double bonds. Especially, an unsatd. polyester resin is preferable because its mol.wt., Tg, and electrification characteristics can be easily controlled and the resin has high strength and a long life.

Filed: 1995-06-29
Abstract: PURPOSE: To facilitate the adjustment of a space between the head sides of nails at a substantially predetermined position with no skill by attaching two gage balls to one of handles in axial series. CONSTITUTION: A gage rod has one end part to which a standard gage ball 12 is fixed, and the other end part to which gage balls each having a diameter different from that of the standard gage ball 12 are attached in axial series. That is, the front end gage ball 13a has a diameter slightly larger than that of the standard gage ball 12, and the inside gage ball 13b has a diameter larger than that of the front end gage ball 13a. Accordingly, for example, when the gage balls 13a, 13b are passed through a space between nails at the same time, even through the gage rod is passed being deviated toward one of the nails in the head side part of the nail, the inside gage ball 13b is shifted widthwise so as to pass the center of the space between the nails.  Accordingly, even through the gage rod is precisely passed through the center of the space between the nails, the adjustment for the space between the nails can be facilitated.

Title: Input buffer
Inventor: SEKIHARA KAZUHIKO
IPC: G06F3/00
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To compensate duty deterioration and suppress decrease in noise margin by providing a means which detects the maximum and minimum values of an input signal, finds the amplitude of the input signal from their difference, and inputs the center of the amplitude as a threshold value to a differential input buffer. SOLUTION: The input signal which is inputted to a reception side from a transmission side through a transmission line is supplied to the forward conversion input terminal 11 of the differential input buffer 1, and a maximum value detection part 2 and a minimum value detection part 3. The maximum value detection part 2 detects and supplies the maximum value of the input signal to a threshold value setting part 4 and the minimum value detection part 3 detects and supplies the minimum value of the input signal. The threshold value setting part 46 calculates the difference between the maximum and minimum values of the input signal, i.e., the amplitude of the input signal and supplies the center of the amplitude as the threshold value to the inversion input terminal 12 of the differential input buffer 1. Consequently, even if the level of signal shifts, the threshold value is always set to the center of the amplitude to compensate the duty deterioration.

Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To improve a connecting and disconnecting property of a cover member by fixing a support bracket of a PTO clutch lever to intermittently operate a PTO clutch mechanism on a back surface of a rear wheel fender part to cover a rear wheel of a travelling machine body. SOLUTION: Support brackets 44, 45 respectively support PTO clutch levers 23, 39 free to revolve and operate in the longitudinal direction. These support brackets 44, 45 are integrally installed on front side inclined parts of left and right rear wheel fenders from the back side. Thereafter, front end sides of the PTO clutch levers 23, 39 supported on each of the support brackets 44, 45 are exposed to front sides of the rear wheel fenders through guide holes formed on the front side inclined parts. Additionally, the support brackets 44, 45 are arranged inside of the machine body rather than a rear wheel 7 and in front of a top part of the rear wheel 7. Consequently, it is possible to directly install the support brackets 44, 45 by using the back surfaces of the rear wheel fenders.  Furthermore, the PTO clutch levers 23, 39 don't stand in the way at the time of connecting and disconnecting a center step 11 and a rear cover 13.
