Title: Ceiling embedment type lighting apparatus
Inventor: SHIYOUJI FUJIO
IPC: F21V17/00
Filed: 1978-05-31
Abstract: PURPOSE: To perform a positive frame engagement with a simple operation by forming a peripheral rib instead of a hole all over the inner periphery in the substantially central portion of a lighting apparatus body.  
     CONSTITUTION: A peripheral rib 10 is formed all over the inner periphery in the substantially central portion of a lighting apparatus body 1. A spring element 9 of a frame member 6 has a recess 8 having such a dimension that it does not normally contact the inner wall of the apparatus body 1. When the spring element 9 is inserted into the apparatus body 1, the recess 8 first contacts the peripheral rib 10 and then passes over it so as to project outwardly, so that its downward slope will be brought into contact with the upward slope of the peripheral rib 10. Thus the engagement is completed and the frame member 6 is held by the apparatus body 1. Accordingly, only if the frame member 6 is pushed up fully, a positive engagement can be achieved without fail, which eliminates the need of confirming the engagement position. Further, there is no possibility of the frame member 6 being held temporarily with the recess 8 of the spring element 9 pressed against the inner wall of the apparatus body 1 in the course of the insertion of the spring element 9 into the apparatus body 1. Thus the desired engagement can be achieved.

Abstract: PURPOSE:To prevent drop of the characteristic by furnishing a gas supply pipe equipped with a gas supply valve at a supply manifold for the fuel gas in each block cell and a gas exhaust pipe equipped with a gas exhaust valve to be connected with the inlet valve on the supply pipe for the fuel gas. CONSTITUTION:When power generation of a fuel battery is to be stopped, an inlet valve 7 for the fuel gas is shut while a gas supply valve 11 and gas exhaust valve 14 are opened. Because the nitrogen gas in a pressure vessel 5 is controlled to a high pressure than the pressure at a supply manifold 2 for the fuel gas, it passes through a gas supply pipe 12 and is supplied into the supply manifold 2 for each fuel gas in block cells 1. At this time, the nitrogen gas purges the fuel gases remaining in unitary cells in these block cells 1 approx. simultaneously, and the purged fuel gases are collected to an exhaust manifold 3 to be substituted by nitrogen gas. This provides quick purging and substitution with nitrogen gas, that prevents exposure at stopping to high temp. condition for a long period of time.

Title: Frequency measuring system
Inventor: SATO YUICHI
IPC: G01R23/10
Filed: 1985-03-29
Abstract: PURPOSE:To attain a sufficiently small measurement error and a high resolution and to measure a signal frequency by generating a stable high frequency signal having the n-fold frequency for the signal to be measured and counting the high frequency signal with the time base of a prescribed time. CONSTITUTION:The output of a frequency divider 115 is so adjusted automatically that this output and the signal to be measured inputted to a phase comparator 111 have the same frequency and have phases synchronized with each other. Consequently, the high frequency signal having the n-fold frequency of the signal to be measured is outputted from the output terminal OUT of a DPLL 110 as the connection point between frequency dividers 114 and 115 phase- synchronously with input pulses. In a frequency measuring means, a counter 121 receives a time base signal of a time T from a time base generator and counts the number of pulses of the high frequency signal form the DPLL 110 on the time base T. This counted value is multiplied by 1/(nT) in a frequency discriminating circuit 122 to measure and output the frequency of input pulses.

Title: Laser printer
Inventor: SHIMADA KAZUYUKI
IPC: B41J2/44
Filed: 1996-03-22
Abstract: PURPOSE: To prevent an image other than a normal image from being generated by the irregular reflection of a light beam by turning the modulation of the light beam OFF right after the incidence of the light beam if detected by an optical sensor. CONSTITUTION: The output of an optical sensor is ANDed with a synchronization detecting modulation signal by an AND circuit 16 and is made so as to be applied to an image scanning clock generator 12 and a synchronization detecting modulation circuit 11 only when the synchronization detecting modulation signal is outputted from the synchronization detecting modulation circuit 11. Consequently, even though noise is entered into the output circuit of the optical sensor when the synchronization detecting modulation signal is not outputted, an image scanning clock is not updated. In this case. the modulation signal is made OFF with the output of the optical sensor because the synchronization detecting modulation circuit 11 makes the synchronization detecting modulation signal fall off with the output signal of the optical sensor.  That is, the modulation of the optical beam is made OFF right after the incidence of the optical beam is detected in the optical sensor.

Abstract: PROBLEM TO BE SOLVED: To select lights of arbitrary wavelengths from a wide-range wavelength range to make it possible to emit the lights of an even quantity-of-light distribution on a substrate by a method wherein the lights are synthesized and emitted onto the photosensitive substrate and a region, where is emitted with the dispersed lights, on the substrate is limited centering around a point, where is emitted with the lights of the prescribed wavelengths. SOLUTION: The lights superposed light (b) from a light source 21 on light (a) from a light source 11 are emitted on a substrate 3. The lights of the wavelength ranges of wavelengths λ1 to λ2 are emitted from the lights from the light sources 11 and 21. However, the light of the wavelength λ1 from the light source 11, the light of the wavelength λ2 from the light source 21, the light of the wavelength λ2 from the light source 11 and the light of the wavelength λ1 from the light source 21 are emitted on the substrate 3 in such a way as to coincide with each other on the substrate 3.  Accordingly, as the light (a) from the light source 11 and the light (b) from the light source 21 are emitted on the substrate 3 in such a way that their spectral intensity characteristics are offset to each other, the intensities of the lights (a+b), which are emitted on the substrate 3, become roughly even within the emitting region of the lights.

Filed: 1982-04-22
Abstract: PURPOSE:To soften the hardened structure in a weld zone and to prevent segregation cracking in site welding of a line pipe by using a cellulose type welding rod of high hydrogen content and preheating the end part of the steel pipe to a specific temp. range. CONSTITUTION:Only the end part of pipes is preheated to a 600-900 deg.C range by any of gas heating, induction heating and resistance heating prior to welding. If the heating temp. is 600 deg.C in this case, a tempering effect is insufficient and if it exceeds 900 deg.C, the hardness does not increase on account of austenitization and the deformation increases during heating and cooling. If the heating time is too long, carbonitride deposits and the quality of material is deteriorated.
