Title: Binocular vision camera for ocular fundus
Inventor: SAKURAI AKIO
IPC: A61B3/14
Filed: 1988-06-24
Abstract: PURPOSE:To enable an ocular fundus to be lighted up and exposed with the definite quantity of light regardless of the size of a pupil by constituting the throttle of a ring opening that the ring opening can be changed in area. CONSTITUTION:Each opening U1 through U3 of an opening throttle plate 35 is selected depending on the diameter size of the pupil Ea of an examined oculus E, and the ring opening D1 through D3 responding to the selected opening U1 through U3 is put into a light path. Even if the pupil Ea of the examined oculus E becomes small in diameter, it is quite impossible that the quantity of incident light is reduced so as to let an ocular fundus become dark for letting observation be hardly made. In addition, when the ocular fundus Er is photographed, an exposure light source 62 is lighted with a reflection mirror removed from the light path. In this case, the opening U1 through U3 responding to the diameter size of the pupil Ea is selected in the same way as before, the ocular fundus Er is thereby exposed with the definite quantity of light regardless of the size of the pupil Ea so that the ocular fundus can be properly photographed.

Abstract: PURPOSE:To obtain a high-quality image by specifying the resistance to be possessed by a ferrite carrier, incorporating a nonconductive black dye or black pigment together with a coloring agent into a toner and specifying the relative dielectric constant thereof. CONSTITUTION:The ferrite carrier to be used is constituted of the complete mixture composed of a metal oxide of Ni, Zn, Mg, Cu, Li, Ba, V, Cr, Ca, etc., and tervalent iron oxide.

Title: Bonding method for cylindrical shaped label
Inventor: ABE TAKEHIRO
IPC: B65C3/20
Filed: 1989-06-20
Abstract: PURPOSE:To prevent the positional discrepancy of a cylindrical shaped label from generating by a method wherein after a cylindrical shaped label is temporarily bonded to a designated position of a container, a main bonding process is performed. CONSTITUTION:A fitting process is performed while a cylindrical shaped label 2 is fitted over a collar part 10, which is provided at the mouth of a container 1, and the container 1, on which the label 2 is fitted, is carried to a preforming process by a carrying conveyor 3. At the preforming process, when an initial heating, for which hot air is blown to the cylindrical shaped label 2, is performed, the cylindrical shaped label 2 is thermally shrunk, and folding lines 20, 20 are eliminated, and the shape is formed into an approximately round shape. When this condition generates around the collar part 10, an idly fitting condition of the cylindrical shaped label 2 to the container 1 is presented. When further heating is started from a front lower spot S in the advancing direction of the cylindrical shaped label, heat shrinkage advances while the label is fastened to the collar part 10. Accompanying with the advancing of the label 2, the label 2 is always heat-shrunk from the lower spot S for respective parts in the vertical direction, and therefore, the label 2 thermally shrinks while being pulled downward, and is temporarily bonded on the collar part 10. The container 1, which has passed the preforming process, enters in a heat-shrinking tunnel 6, which is composed of a heating oven, and a bonding process of the cylindrical shaped label 2 is performed. By this method, a cylindrical shaped label can be quickly and precisely bonded at a designated position on a container with a simple constitution of a device.

Title: Electric charge type flow rate measuring instrument
Inventor: MORI HIDEAKI
IPC: G01F1/56
Filed: 1987-06-26
Abstract: PURPOSE:To measure the flow rate of low-viscosity fluid such as superfluid helium by changing the movement of the charge particles generated in the fluid in association to the flow rate of the fluid and taking said movement as an electric signal. CONSTITUTION:A tungsten wire 5 having a small diameter glows white and emits thermions when current is passed to the wire by a heater power supply 7. The thermions pass a gaseous helium layer and enters the superfluid helium. The thermions released from the wire 5 which is a negative electrode move toward a positive electrode 2 while expelling the helium atoms. if a strong electric field is generated between the collector electrode 2 and the wire 5 by a heating power supply 6. The current flows between the electrode 2 and the wire 5 upon arriving of the thermions at the electrode 2. The charged particles receive the force in the fluid direction by the flow of the helium and the number of the particles arriving at the electrode 2 fluctuates in proportion to the velocity of flow, thus changing the voltage. The flow rate of the low- viscosity fluid such as superfluid helium is, therefore, measured by measuring the current flowing in an ammeter 8.
