Title: Power supply monitor
Inventor: SHITANI TAKESHI
IPC: H02H7/20
Filed: 1994-12-01
Abstract: PURPOSE: To prevent the deterioration in performance of a power supply monitor by A/D converting a monitored signal output from a signal converting section and then detecting an abnormal shape of a monitored signal waveform which has been A/D converted. CONSTITUTION: An ac signal from an ac power supply 1 is photoelectric- converted by a signal conversion section 2 into an optical signal and then the optical signal is converted into an electric signal again and thereby such a monitored signal is obtained that has a lower voltage than the ac power supply and has a voltage waveform proportional to that of the ac voltage. This monitored signal is supplied to an A/D converting section 3 and made into a digital signal. Then, a CPU 4 recognizes how different in the waveform the digitalized signal is from what it should be. If there is an abnormality in the waveform of the digitalized signal, the CPU 4 outputs a signal to tell the abnormality of the waveform of the digitalized signal. By this method, the deterioration in performance of a power supply monitor is prevented even if it is made small-size and light-weight.

Title: Selective carcinostatic agent
Inventor: NAKANISHI TOSHIHIRO
IPC: A61K45/00
Filed: 1991-11-11
Abstract: PURPOSE:To provide the antitumor medicine capable of selectively acting only on cancer cells. CONSTITUTION:The selective carcinbstatic agent is characterized in that a basic amino group in a monoclonal antibody produced from a hybridoma originated from a human cancer antigen is crosswisely bound to the free amino group of a carcinostatic substance through a carbon-nitrogen bond in a Schiff's base or aminomethyl bond with a saturated divalent aldehyde. The hybridoma includes the fused cell of the splenic cell of an animal (BALB/mouse) sensitized with human malignant melanoma with the myeloma cell of an animal. Since the bound product expresses strong affinity only to a specific cancer cell having an adoptive antigen, kills only the cancer cell and inhibits its multiplication, but does not substantially affect normal cells, the bound product can be expected as a selective carcinostatic agent.

Title: Photoreceptor for optical pickup
Inventor: ISHIHARA HISAHIRO
IPC: G11B7/13
Filed: 1993-12-22
Abstract: PURPOSE:To detect signals with high sensitivity by removing influences of an insensible band of a 4-split photodetector in an optical pickup. CONSTITUTION:A signal light enters from a rear face of the photoreceptor for an optical pickup (from the side of a substrate 2). At this time, incident beams are divided by an auxiliary lens 1 which is set at a substrate part and has a converging function, and converged to a central part of each element in a photodetecting area. A rate of the light power entering a central insensible band of the whole 4-split photoreceptor is greatly reduced, and most of the light power enters an effective part of each element. Even when a diameter of the light spot is increased/decreased or a position of the light spot is changed as a result of a servo operation of the lens, a changing amount of the power falling to the insensible band is negligible, not inviting a change of an RF output (i.e., jitters).
