Title: Paper feeding cassette
Inventor: HASHIGUCHI TOSHIAKI
IPC: G03G15/00
Filed: 1985-10-25
Abstract: PURPOSE:To make a residual quantity of copying paper detectable at one sheet unit and improve a degree of tection accuracy, by attaching an L-shaped paper residual quantity detector, which has a light source built in one side and also has drive and output circuits of a light receiving device built in the other, to one corner of a cassette. CONSTITUTION:When sheets of copying paper 5 are decreasing, the copying paper 5 is pushed up by a spring 20 being attached to an interval between a bottom plate 1 and a movable bottom plate 4 of a paper feeding cassette, but an upper limit position of the copying paper 5 is restricted by an upper limit stopper 9 and a rear stopper 10. Here light is irradiated from a light source 13 to be built in one side of a paper residual quantity detector 12 toward a lens 14 and a light receiving device 15 to be built in the other, but this irradiated light is intercepted as far as a portion for thickness of the copying paper 5 so that a light receiving quantity increases as much as a portion for that the thickness of the copying paper 5 is decreased. Therefore, if numbers of a light receiving sensor of the light receiving device 15 being worthy of a position making a peak seeable from an O position are counted, a paper residual quantity is made out, thus accuracy in paper residual quantity detection is improvable.

Title: Thermal head, thermal printer, and printing process thereof
Inventor: NAKAJIMA TAKASHI
IPC: B41J2/375
Filed: 1990-09-07
Abstract: PURPOSE:To prevent heating resistors from being overheated and perform a uniform thermal printing by a method wherein a conduction time is regenerated by using an 'H' level period of a printing control signal as a trigger. CONSTITUTION:When a first printing control signal S1 controlling a heat supply timing to heat-sensitive paper 19 is inputted to a monitor timing generation means 11A and a first signal output means 11B, the monitor timing generation means 11A outputs a monitor timing signal S0 to a signal output means 11B. Then, based on the first printing control signal S1 and the monitor timing signal SO, the signal output means 11B outputs a second printing control signal S2 to a printing data input processing means 12. With the input of the second printing control signal S2 and printing data Din, the printing data input processing means 12 outputs a heating element selection signal SH to a plurality of heating elements 13. Even if the 'H' level period of a signal S1 is extended by a malfunction of an external circuit or the like, an excessive heat supply to the heating element can be inhibited because a signal S2 is regenerated by using the signal S1 as a trigger.

Title: Station equipment data restore control system
Inventor: YASUDA KAZUHISA
IPC: H04L29/08
Filed: 1989-09-12
Abstract: PURPOSE:To restore the state before the change without stopping the call processing operation by adding time information to restore commands to store them in order and taking out them in the reverse order. CONSTITUTION:When commands required for the change of station equipment data are inputted from an input/output terminal equipment 1, they are sent to a command execution and restore instructing part 3 through a command execution and restore request part 2. The instructing part 3 not only changes station equipment data but also causes a restore command generating and storying part 5 to generates a restore command and gives time information to it to store it. When time information of the command as the restore object is given from the device 1 to input a restore request command in the case of restore, the restore command is taken out of the storing part 5 through a restore command taking-out part 4. At this time, the taking-out part 4 takes out restore commands in the order opposite to the input order to send them to a restoring part 2. Thus, restoration is easily performed without stopping the call processing operation of an exchange.

Abstract: PURPOSE:To detect a very small flow rate of a fluid by providing a body with a hollow part where the fluid passes and two PTC (positive temperature coefficient) thermistors with the same characteristics which are laid out side by side in the flow direction of the fluid provided at the hollow part. CONSTITUTION:The flow rate sensor consists of a body 3 with a hollow part 3b where a fluid passes and two PTC thermistors 1 and 2 with the same characteristics which are laid out side by side in the flow direction of the fluid. When measuring the flow rate of gas as the fluid, a pipe for flow rate measurement is connected to internal threads 3d and 4d of the sensor and a voltage is applied between terminals A and C from a power supply. When a voltage is applied to the PTC thermistors 1 and 2, the PTC thermistors 1 and 2 release heat and the thermistors 1 and 2 are kept at specific temperatures. When the fluid is allowed to flow to the hollow part 3b in this state, a temperature difference occurs in two PTC thermistors 1 and 2. By measuring the voltage between terminals B and D and current between the terminals B and D, a small change in the flow rate can be detected.

Title: Device and method for installing coil spring
Inventor: TOYAMA SHINJI
IPC: B25B27/30
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To install a coil spring on a shock absorber readily and surely irrespective of the type of the coil spring. SOLUTION: The upper end part of the coil spring 2 is pressed against claws 42 and 43 by raising the shock absorber 1 to compress the coiled spring 2. Guides 46 and 47 are disposed on the side of the coil spring 2 to prevent the coil spring 2 from being pulled by either of the claws 42 and 43 when the claws 42 and 43 are extracted from the coil upper end part, coming off the concentric circle of an upper support 6. Thus, even for coil springs having the numbers of turns and material diameters different from each other, the coil spring compressing operation can be performed without adjusting the positions of the claws 42 and 43 of an assembly head. Also, adjustment of the positions of the claws 42 and 43 is not necessary according to the phase of a coil winding direction relative to the claws 42 and 43.

Title: Digital input device
Inventor: NOGUCHI MASAHIRO
IPC: G05B1/01
Filed: 1983-12-17
Abstract: PURPOSE:To obtain an excellent circuit response to the frequency variation of an input signal by detecting the moment when the level of an input AC voltage exceeds a fixed threshold and catching the logical level of the input signal at the moment, and then, performing the process by using the logical level as a logical signal. CONSTITUTION:When an AC signal produced at a signal source E and switch S1 is inputted into an input point I1, the AC signal is rectified by a diode D1 and resistor R1 and inputted into a comparator CP1. The comparator CP1 compares the input voltage with a threshold and outputs a prescribed logical pulse signal to the input port D of a latch circuit L1. On the other hand, the AC voltage of the signal source E is inputted into another input point Is and the AC voltage is further inputted into another comparators CPs after rectification. The comparator CPs compares the input voltage with a threshold and outputs a reference logical pulse signal to the input port T of the latch circuit L1. Now, since the threshold of the comparator CP1 is lower than that of the CPs and the input signals are supplied from the common signal source, the prescribed logical pulse signal output of the comparator CP1 changes ealier than the outut of the comparator CPs. Therefore, the latch circuit L1 can catch and output stable logical signal data always.
