Title: Discrimination device for photosensitive drum
Inventor: NAKAZAWA SUSUMU
IPC: G03G15/00
Filed: 1987-10-30
Abstract: PURPOSE:To constantly read a characteristic value and to eliminate a special memory by forming two characteristic displaying parts, which are annular shaped and coaxial with the axis center of the photosensitive drum, at the edges of a photosensitive drum, providing characteristic detecting sensors on a main body side and discriminating the characteristic of the photosensitive drum. CONSTITUTION:Disk-shaped flanges 2a and 2b are provided respectively at the side edges of the photosensitive drum 1 as a means for displaying two characteristics of the photosensitive drum 1. The flanges 2a and 2b are coaxial with the axis center of the photosensitive drum 1, and their outer diameters are adjusted in the way that the outer diameter of the flange 2a at the right side responds to variance on the electrifying characteristic of the photosensitive drum 1, and the outer diameter of the flange 2b on the left side responds to the variance of photosensitivity etc. When the photosensitive drum 1 is fitted in the main body, two particular characteristics of the photosensitive drum 1 are detected by means of the characteristic detecting sensors 3a and 3b, and an influx voltage value and the AVR value of a light source are automatically set. Since the characteristic displaying parts 2a and 2b are annular-shaped, frequent reading is possible regardless of the rotating position of the photosensitive drum 1. Thus a memory and the like for storing a characteristic value becomes needless.

Title: Segment-shaped flexible housing
Inventor: JIEIMUZU DANKAN SHIYOO MAACHIN
IPC: H02G3/04
Filed: 1991-10-25
Abstract: PURPOSE: To provide a segmented flexible housing which can endure a big bending force by providing a conduit contained in a casing made of plural confronting segments, means to connect the segments so that they can be bent and an end surface. CONSTITUTION: Segments 2A, 30, 2B are mutually connected by means of an endless ligament 70 made of Kevler with 2 passages 66, 68 passing through a groove on one of their sides. Vertical end surfaces 16, 38 are confronting each other, and prevent further bending. When a bending of 13 degree is produced, bending from that position in other direction is produced until the first end surfaces 44, 18 contact each other. At its maximum bending, outer edge parts of a partial cylinder surface are kept segregated each other, and there is no such danger that jackets 60, 62 are caught between these outer edge parts. Thereby, degree of bending can be controlled under any inclining condition, that is yawing condition, of a submarine.

Title: Crt picture tube
Inventor: NAGASAWA SHIGERU
IPC: H04N17/04
Filed: 1989-10-27
Abstract: PURPOSE:To execute the GAIN control of a video amplifier, a cut-off adjustment, and a white balance adjustment by generating a synchronizing pulse for clamping and a white pattern signal which are synchronous to each other using the low pressure winding wire output pulse of a fly-back transformer, and switching them with a pattern changeover switching means. CONSTITUTION:Means 60, 62 for generating the video signals which express the timing pulse for clamping and the white pattern and are synchronous with each other, a pattern changeover switching means 68 which switches a CRT screen with a white pattern mode or a black pattern mode, and a means 66 which detects whether or not an external video signal is inputted to a video input terminal and prohibits the use of the synchronizing pulse for clamping and the white pattern video signal when it is inputted, are provided. Therefore, the low pressure winding wire output pulse of a fly-back transformer 50 is generated in a horizontal fly-back period, so the waveform of this pulse can be formed. Thus, the GAIN control of the video amplification circuit, the cut-off adjustment, and the white balance adjustment can be executed without connecting a special external video signal generator.

Title: Production of maleimide
Inventor: KUME YASUHITO
IPC: C07D207/448
Filed: 1992-10-20
Abstract: PURPOSE:To produce a maleimide in high yield by heating a maleinamic ester and carrying out alcohol removal reaction to form a ring closure imide while distilling away a formed alcohol and a maleimide. CONSTITUTION:A maleinamic ester of the formula (R is 1-8C alkyl) is heated, alcohol removal reaction is carried out while distilling away an alcohol and a maleimide formed in the reaction out of the reaction system so that reaction between the formed maleimide and the maleinamic ester of the raw material is prevented and polymerization reaction of maleimide is suppressed to give a corresponding high-purity N-nonsubstituted maleimide in high yield and economically. Maleimide, for example, is required to have heat resistance. Maleimide is useful as an intermediate raw material for medicine and agricultural chemical besides raw material for synthetic resin. Since the alcohol removal reaction by this method is readily advanced, maleimide is obtained more efficiently than using a dehydrating agent. Since a specific purifying process is not required, manufacturing cost can extremely be reduced.

Title: Heat pump hot-water supply device
Inventor: OTSUBO MICHIO
IPC: F24H1/18
Filed: 1987-11-06
Abstract: PURPOSE:To enable judging an operational failure or trouble of a heat pump hot-water supply device properly and immediately by installing failure diagnosis section which receives detected values from all temperature sensors and carries out failure diagnosis based on a program where memory is stored previously and a display output section which issues an alarm in emergency. CONSTITUTION:Numerals 34 stands for the temperature of hot water supplied from a high temperature hot water storage tank 21 while numerals 35 stands for the temperature of hot water in a lower temperature hot water storage tank 28. Numeral 36 stands for the temperature of hot water in a return piping. Numerals 37a and 37b stand for the inlet temperature and the outlet temperature of a high temperature side heat pump 22 respectively. Numerals 38a and 38b stand for a temperature sensor which detects the inlet temperature and the outlet temperature of a low temperature side heat pump 29 respectively. A failure diagnosis program in a failure diagnosis section 47 allows a hot-water supply device to start action by turning ON a power supply switch. The temperature sensors at the various section as described above input the temperature at each section into the failure diagnosis section 47. Based on the detected values, the program forms judgement as to whether the temperature of the lower temperature side hot-water storage tank is higher than a predetermined value A or not. When it is higher than the predetermined value A, the program passes judgement as to the presence of other troubles. If no trouble is detected, it is judged that the control device for a hot-water circulation pump 45 is subjected to operational trouble, and that the pump continues its operation without control. The program gives warning, such as through voice or the like, and outputs similar warning to a display section 40 and a printing section 41. When not trouble is detected, the temperature detection continues operation as it is.

Title: Magnetic recording and reproducing device and magnetic head
Inventor: FUKUDA KAZUMASA
IPC: G11B19/20
Filed: 1988-11-08
Abstract: PURPOSE:To obtain the durability of a high level, and also, to execute magnetic recording and reproducing without generating a head attraction phenomenon by combining a magnetic disk and a magnetic head, and allowing them to have a characteristic by which a coefficient of friction between both of them is varied suddenly against a relative speed between the magnetic disk and the magnetic head. CONSTITUTION:When a magnetic disk 3 whose surface roughness Rmax is <=10nm is used, even when a magnetic head 4 is operated by such a very low floatation quantity as the head is considered to come into contact with the surface of the magnetic disk, a collision between the magnetic disk 3 and the magnetic head 4 is scarcely generated. Also, by combining the magnetic head 4 which is formed like a rectangular parallelopiped as a whole, and in which the whole surface of the medium opposed surface is like a plane and the plane area is <=2mm<2> to the magnetic disk 3 having a surface property, the attraction phenomenon of the magnetic head is scarcely generated at the time of contact, start and stop. In such a way, the durability of a high level is obtained by a very low floatation quantity, and also, magnetic recording and reproducing can be executed without generating the head attraction phenomenon.
