Abstract: PURPOSE:To make an optical dividing member small in size and light in weight by making the width of the optical dividing member narrower than the outline length of a solid state image pick-up element in a picture element string direction. CONSTITUTION:Concerning a light flux which is made incident from a lens barrel 21 to the edge part of a picture element string 25b, the light flux is generally passed through an extremely inner side from the outside of a CCD25 in the picture element string direction. Accordingly, even if the width of a prism 22 is made extremely narrower than the outline length of the CCD25 in the picture element string direction, the optical path of an optical system can be sufficiently covered. Accordingly, the prism 22 itself is made small in size and light in weight and simultaneously, fitting members 24a and 24b are formed as shown in the figure so that a package part 25c of the front surface of the CCD25 can be joined. Then, a width is made minimum. Thus, a reading unit 20 is made extremely compact.

Title: Developer concentration measuring apparatus
Inventor: YAGI ATSUSHI
IPC: G01N21/15
Filed: 1985-12-18
Abstract: PURPOSE:To enable a stable concentration measurement for a long time, by a method wherein liquid films are formed at a plurality of openings provided in the perimeter of a developer holding member to be held on the outside of a liquid tank and a beam transmissivity of the liquid film is detected to measure the concentration. CONSTITUTION:As a stepping motor 12 run with a motor driving circuit 20, a disc-like developer holding member 11 is driven to rotate. Among openings 11a-11n in the perimeter thereof, those immersed into the developer are filled with a developer D and when they are taken out of a liquid tank, a meniscus- like liquid film is formed. When this liquid film moves to the position where a light emitting element 13 and a light receiving element 14 are arranged facing each other, a beam transmissivity of the liquid film is optically detected to measure the concentration of the developer. With such an arrangement, a meniscus-like liquid film always having a fixed thickness is formed stably at the opening of the developer holding member 11. Moreover, as this opening is cleaned up automatically by a developer injected from a nozzle 37 timely, the clogging of the opening can be avoided as caused by toner or the like in the developer.

Inventor: KUROKI KAZUO
IPC: H03K17/687
Filed: 1986-12-01
Abstract: PURPOSE:To stabilize an action at a switch-off process by turning off forcibly a semiconductor switch to discharge a charge accumulated to the capacity between gate and source of MOSFET at the time of off, with the resetting energy of a pulse transformer. CONSTITUTION:To a diode 4 connected to one side terminal of the secondary winding of a pulse transformer 3, a resistance 12 is connected in parallel and a circuit to ignite a semiconductor switch 7 with the resetting energy of a pulse transformer is formed. Thus, at the secondary winding of the pulse transformer 3 at the time of an off signal, a voltage lower than the gate voltage of an MOSFET 9 is generated with the resetting energy. Consequently, as the control signal of the semiconductor switch 7 to discharge a charge accumulated at the capacity between the gate and source of the MOSFET 9, the on condition of the semiconductor switch 7 is maintained with the resetting energy and as the result, the voltage between the gate and source of the MOSFET 9 is reduced up to a sufficiently low voltage. For this reason, even when a voltage with a steep change is impressed between the drain and source of the MOSFET 9, the circuit is stably operated.

Filed: 1988-11-14
Abstract: PURPOSE:To display the trace contents while carrying out a down-counting action at and after the stop point memory address by using a synchronizing up-down counter to a trace address counter in a pre-mode. CONSTITUTION:A pre-mode signal, an address update signal, and a clock signal are inputted to a 3-input AND circuit 5. The output of the circuit 5 is inputted to the down-count terminal of a synchronizing up-down counter 1. Thus the counter 1 starts a down-counting action. The count signals are successively outputted through the output terminal of the counter 1 with input of a trace instruction signal. These count signals are sent to a trace memory to trace a program. While the count signals are also outputted through the output terminal of the counter 1 with input of a trace contents display signal. These count signals are sent to the trace memory to display the trace result. In a post-mode the addresses can be displayed while these addresses are successively counted up (+1) from 0 by the address update signal. Thus it is possible in a pre-mode to display addresses while these addresses are successively counted down at and after a stop address by the address update signal.

Title: Automatic ice making device
Inventor: MIYAMOTO ICHIRO
IPC: F25C1/18
Filed: 1990-10-24
Abstract: PURPOSE:To enable ices having a high degree of transparency to be produced by a method wherein when water in a water supply tank is fed into an ice making pan through a water storing pan, a freezing action of one direction is carried from a surface of the water to a downward direction with cold air within a cooling chamber by a thermal insulation by a thermal insulating tank and a heating action with a heater from the lower surface. CONSTITUTION:When water temporarily stored in a water storing pan 21 from a water supply tank 18 is supplied by a water supply pump 22 into an ice making pan 33, the cold air cooled by a cooling device 8 is made to flow by a blower 9 to the ice making pan 33. In concurrent with a starting of the cooling action, a metallic plat 26 at a bottom surface is heated by a heater 28 within the thermal insulating tank 24. In addition, since the ice making pan 20 is covered by a thermal insulating material 27, a cooling action from an outer circumference is also restricted and a heat transmitting material efficiently dampens a reduction in water temperature at the bottom part of the small partition part 30 as well as heat from the heater 28, resulting in that a freezing action is progressed in one direction from up to the bottom of the ice making pan 29. As a result, as the ice is being produced, gaseous component or various impurities contained in the water are crystallized out of the ice crystal, discharged into the lower non-frozen water and so the ices having a high degree of transparency can be attained.
