IPC: C12M3/00
Filed: 1986-04-01
Abstract: PURPOSE:To increase cell-adhesion area of a cell-supporting member and to enable the use of the member in production plant, by attaching cells to a culture cell-supporting member composed of a ceramic block containing a number of through-holes having specific inner diameter. CONSTITUTION:The objective supporting member is composed of a ceramic block containing a number of through-holes 1 of 0.01-5mm diameter. The ceramic block is enclosed with an outer shell 2 to retain culture medium. The total surface area of the inner wall of the through-hole 1 is extremely large because of the presence of a large number of through-holes 1 and the medium can be infiltrated and discharged without being retained in the block because the holes are extended through the block. The breakage of cells caused by the rubbing of cells against each other can be eliminated by attaching the cells to the culture cell-supporting member. The cell adhesion area can be increased and the member can be used in a production plant.

Title: Dc voltage-controlled phase adjusting circuit
Inventor: SHINOHARA KOJI
IPC: H04N9/64
Filed: 1987-03-27
Abstract: PURPOSE:To decrease the number of terminals in case of circuit integration by applying vector synthesis to a chroma signal subjected to amplitude control by a DC voltage applied externally and a burst signal shifting the phase of an input burst signal by a prescribed quantity, adding the result to a chroma signal to obtain a signal output thereby eliminating the need for an externally mounted passive component. CONSTITUTION:The base of a burst and a chroma signal inputted to a phase shift circuit 4 are changed by a prescribed quantity and inputted to 2nd burst gate circuit 5 and a burst signal changed by the prescribed quantity is outputted. A 2nd adder circuit 6 varies the synthesis ratio of the burst and chroma signal inputted from a 1st adder circuit 3 and the burst signal from the gate circuit 5 and the result is outputted from an output terminal 11. As a result, the amplitude of the burst/chroma signal is varied in response to the external control voltage applied to a color control terminal 12 and the phase of the burst signal only is varied in response to the external control voltage fed to a phase control terminal 14. Thus, in case of circuit integration, the number of terminals is reduced and the number of externally mounted components is reduced remarkably.

Title: Color image forming method
Inventor: SAKAI TOSHIO
IPC: B41J2/525
Filed: 1992-02-26
Abstract: PURPOSE:To provide a color image forming method by which accurate color reproducibility is realized even in the case of one picture element and multi-gradation. CONSTITUTION:An original is read and toner concentration for each picture element is calculated (1-3). The toner concentration is converted to main electrostatic latent image potential (4). The main electrostatic latent image potential is corrected for an electrostatic latent image concerned in second and succeeding developing by considering the change of surface potential caused by the toner sticking on the surface of a photosensitive body before development (5). The electrostatic latent image potential for each photoconductive layer is obtained by considering the coated electrostatic latent image potential (6). Image exposure is performed based on the electrostatic latent image potential (7-11). In the case that there is a picture element having a polarity different from the electrifying polarity of the photoconductive layer at the stage of (5), it is conceivable to perform correction by the main electrostatic latent image potential having the different polarity and newly set the electrostatic latent image potential. In the case that there is a picture element exceeding the maximum potential of the photoconductive layer at the stage of (5), it is conceivable to set the electrostatic latent image potential by regarding the exceeding main electrostatic latent image potential as the new maximum potential.

Title: Gas laser oscillator
Inventor: NISHIDA KOICHI
IPC: H01S3/038
Filed: 1990-03-27
Abstract: PURPOSE:To offer a small-sized gas laser oscillator whose structure is simple and whose oscillation efficiency is high by a method wherein at least one out of paired dielectrics arranged and installed near individual discharge electrodes is formed cylindrically and its inside is coated with a metal to form a discharge electrode. CONSTITUTION:A cylindrical dielectric 11 is inserted into an outside wind tunnel 1; a second discharge electrode 13 is formed at its inside. The outside wind tunnel 1 itself can be made small; a gas laser oscillator can be made small-sized and its structure can be simplified. In addition, when the frequency of a high-frequency voltage to be applied across a first discharge electrode 6a and the second discharge electrode 13 is reduced, the reactance of an interconnection from a power supply to the electrodes is reduced and the interconnection is made easily. Since the inside of the cylindrical dielectric 11 is coated with a metal to form the second discharge electrode 13, a void is not formed between the dielectric 11 and the metal coating part. As a result, it is possible to prevent a partial electric discharge inside the void, and a uniform electric discharge can be obtained between dielectrics 7a, 11.
