Title: Powdery material developing device
Inventor: NAKAZAWA NOBUO
IPC: G03G15/08
Filed: 1986-06-13
Abstract: PURPOSE:To hold and control the quantity of a developer with a high precision by sweeping the developer toward a developing sleeve at a period, which is different among plural divided areas in the lengthwise direction of the developing sleeve, by a rotating developer agitating member. CONSTITUTION:A crank-shaped rotting agitating rod member 4 which has a length corresponding to an overall length L of a developing sleeve 2 consists of agitating rod parts 4A and 4B which correspond to areas LA and LB in the lengthwise direction of the sleeve 2 and have phases shifted from each other by about 180 deg.. Since the member 4 is formed in this manner, the apparent variance of the quantity of the developer due to rotation of the member 4 is shifted between developer accumulation parts of areas LA and LB of the member 4 by a half period per one rotation of the member 4. As the result, apparent variances of the quantity of the developer in areas LA and LB are averaged with respect to the overall area L of the sleeve 2 and this averaged result is obtained as the sensor output of an antenna line. Consequently, the degree of variance of the sensor output accompanied with rotation of the member is reduced to a half, and the quantity of the developer is held and controlled with a high precision.

Title: Spectroscope for two-dimensional object
Inventor: NAGOSHI TOSHIYUKI
IPC: G01J3/28
Filed: 1990-05-28
Abstract: PURPOSE:To perform the spectroscopy of each point of a two-dimensional body at the approximately same time by moving the two-dimensional body because a spectroscope can impart the spectrum of each point of the body in one-dimensional direction. CONSTITUTION:The light which is cast through an incident slit 52 in parallel with the direction of the grating of a diffraction grating 51 is converted into the parallel light through a concave mirror M1. The light is cast on the diffraction grating 51 and diffracted at an angle corresponding to a wavelength. The spectral distribution is imparted on a spectroscopic surface 53 which is conjugate with the incident slit 52 with a concave mirror M2. A two-dimensional photodetector 54 is arranged on the spectroscopic surface 53. The height of the slit 52 is made to correspond to the direction (y) of the incident surface, and the wavelength is made to correspond to the direction (x). Then, the distribution of intensity is measured. In this way, the spectroscopic measurement of a one-dimensional body corresponding to the incident position of the slit 52 can be performed. A two-dimensional body 55 is placed at the side front of the incident slit 52, and the spectroscopic measurement at the position of the body corresponding to the incident position of the slit 52 is performed. During this period, the two-dimensional body 55 is moved in the direction of (x). Thus, the spectrums from the points of the two-dimensional body 55 can be measured at the approximately same time.

IPC: F23N5/26
Filed: 1989-05-31
Abstract: PURPOSE:To specify the cause of an abnormality and facilitate a recovery from the cause by storing and displaying a time from a delimiter time in danger of the generation of an abnormal condition to the time of the generation of the abnormal condition. CONSTITUTION:A safety device is provided with a timer circuit 2 and a safety circuit 3 which always monitors the condition of a burner 1 and emits an alarm or stops the burner 1 in an abnormality.

Title: Device for controlling oil pressure of automatic transmission
Inventor: BABA FUMIAKI
IPC: F16H61/02
Filed: 1988-06-04
Abstract: PURPOSE:To sufficiently ensure the responsiveness of oil pressure control at the time of low oil temperature by selecting the pressure level of the source pressure by means of a pressure reducing valve so as to get a higher pressure level as the oil temperature is lower via a selector valve in accordance with an oil temperature. CONSTITUTION:At the time of 1-2 gear change, for example, a joining oil pressure is fed from a 1-2 SV (shift valve) 56 to the apply side oil chambers 23c of a 2-4 brake 23, while carrying out the pressure regulation of a release side oil chamber 23d by duty controlling a DSL (dust solenoid) 45C and by regulating the pilot pressure of an SPCV (servo-pressure control valve) 48, i.e., the oil pressure is rapidly lowered at the start of control and, after being further gradually lowered, the oil pressure is again rapidly lowered to zero to relieve the shock at the time of speed change. At this time, when oil temperature is below a defined value, a solenoid DSL 202 is controlled to reduce the pilot pressure of a selector valve 201 to carry out switchover from a first pressure reducing valve 44a to a second pressure reducing valve 44b, thereby increasing a source pressure to cover the delay of responsiveness. Thereby, the responsiveness of oil pressure control by means of duty control can be ensured even at the time of low oil temperature.

IPC: H04L12/437
Filed: 1983-07-28
Abstract: PURPOSE:To automate loopback operation in a dual-loop transmission system without using any special monitoring device by the ceasing of the identification signal of a stand-by transmission line and a warning signal. CONSTITUTION:Respective information processors 21a, 21b, and 21p include sense circuits 24 (24a and 24b) for an in-use transmission line, a warning frame transmitting circuit 29b, and an unshown sense circuit for a stand-by transmission line. The in-use transmission line 22 is normally used to perform communication between information processors. When the in-use transmission line 22 is normal, the identification signal of ''0101...'', etc., is transmitted through the in-use transmission line. If the in-use transmission line 22 is broken at a point A, the sense circuit 24b of an information processor 21b detects the break of input, so the information processor 21b performs loopback operation for itself and also transmits the warning signal from a warning frame transmitting circuit. An information processor 21a, on the other hand, performs loopback operation for itself when detecting the breaking of the identification signal of the stand-by system and receiving the warning signal.

Title: Magnetic bubble memory device
Inventor: YOSHIOKA SHINYA
IPC: G11C19/08
Filed: 1979-10-26
Abstract: PURPOSE: To make it easy to detect a data pattern having a continuous bubble string by providing an expander with the prescribed amount of magnetization right behind a detector.  
     CONSTITUTION: Magnetic bubbles transferred are expanded by chevron expander 10 and, after being detected by detector 1, move to chevron expander 21. Expander 21 is narrowed in pattern width and has the less amount of magentization of a chevron pattern, induced in a revolving magnetic field, than the counterpart of detector 1 and it is hard to hold bubbles expanded, so that bubbles will be easy to contract. Therefore, when specially a continuous bubbles arrive, a bubble arriving expander 21 firstly is contracted and bubbles reaching detector 1 are held stably expanded with a little influence of a leakage magnetic field from the preceding bubble.
