Title: Tube-form bulb
Inventor: MAEDA KAZUO
IPC: H01K1/24
Filed: 1989-02-09
Abstract: PURPOSE:To prevent the instability of the light quantity by forming a flat part at a part of a short bar other than the part inserted to an unlighting coil. CONSTITUTION:A flat part 15 is formed at a part of a short bar 14 other than the part inserted to an unlighting coil. As a result, even though the inner diameter of the unlighting coil is smaller than the outer diameter of the tip 5 of the short bar 14, the short bar 14 is not slided between fingers by the flat part 15 when it is inserted to the unlighting coil by rotating and holding it with plural fingers. Consequently, the tip 5 of the short bar 14 can be inserted to the unlighting coil 7 smoothly, and the unlighting coil is never made in a floating condition to the tip of the short bar even though the welding position is uneven. The light quantity is never made unstable, consequently.

Title: Method of polishing brittle substance
Inventor: TANIGUCHI YOSHIHARU
IPC: B24B7/22
Filed: 1979-03-15
Abstract: PURPOSE: To smooth the flow of a brittle substance such as ceramic in a polishing process and the discharge of polished chips when polishing the brittle substance such as ceramic, by setting a gradient in the flowing direction of the polished substance.  
     CONSTITUTION: A brittle polished substance M is caused to go through between polishng wheels along guide plates GP inclined at an angle of θ to the horizontal plane. Both the sides of the substance are thus polished. Since the guide plates GP are inclined, extraneous matters H such as the chips of the polished substance do not stay inside the guide plates GP but flow in the same direction as the polished substance and are discharged. Therefore, both the sides of the substance are smoothly polished.

Title: Multivalue gradation recording method
Inventor: SHIRAIWA KEISHIN
IPC: H04N1/00
Filed: 1990-02-09
Abstract: PURPOSE:To obtain a high definition picture recording without using large scale and expensive hardware by outputting the picture by means of a satisfying the conditions of the resolution degree of a prescribed range and the number of gradations more than a specified value. CONSTITUTION:A lateral axis shows the number of the gradations and a vertical axis shows a picture quality in a graphic. A solid line shows a relation between the number of gradations and the picture quality as to 600dots/inch, a dotted line does as to 900 dots/inch, and a broken line does as to 1200 dots/inch in the graphic. As it is evident from the graphic, the picture quality does not considerably improve even if the number of gradations and resolution are improved when resolution is more than 600 dots/inch and the number of gradations A is more than 48 value. Namely, the picture quality is saturated when resolution is 600 dots/inch and the number of gradations is 48 value, whereby an evaluation value at that time is generally 'Good'. Furthermore, the evaluation value of the picture quality comes to generally 'Common' when resolution is more than 500 dots/inch and the number of gradations is about >=30-value.

Abstract: PURPOSE:To attain display of good quality without dividing a picture into two even in case of pattern deviation by providing parts, where no electrodes are formed, in positions between adjacent picture elements near end parts of extensions of electrodes for signal. CONSTITUTION:Time division driving signals applied to electrodes C1-Cn out of m numbers of scanning electrodes C are applied to electrodes Cn+1-Cm, and electrodes A and B for signal are extended from both ends toward mutual electrodes to form extension ends between electrodes Cn and Cn+1. Parts D where electrodes are removed are formed between picture elements near extension ends of electrodes A and B; and in case of the electrode A, parts D are formed between electrodes Cn and Cn-1, between electrodes Cn-1 and Cn-2, between electrodes Cn-2 and Cn-3, and between electrodes Cn-3 and Cn-4, and the part D is larger according as it approaches the extension end part of the electrode A and is smaller to disappear according as it goes away from the A. Parts D are formed similarly with respect to the electrode B; and therefore, the picture does not look divided into two on boundaries between electrodes Cn and Cn+1, and a good display quality is kept.

Title: Semiconductor laser device and manufacture thereof
Inventor: HAMADA TAKESHI
IPC: H01S5/16
Filed: 1983-02-25
Abstract: PURPOSE:To prevent end-deterioration due to no light emitting recoupling from happening by a method wherein no current supplied mechanism is adopted near end inside a laser chip. CONSTITUTION:The first current strangulating layer 9, the second current strangulating layers 10, 11 are successively grown on a substrate 1. Firstly two parallel ridges are separately formed. The bottom of the groove between ridges reaches the substrate 1 near the central part of laser but remains in the layer 11 near end. Secondly a clad layer 2, an active layer 3 and another clad layer 4 are successively grown on the substrate 1 by the second liquid epitaxial growth. Lastly stripe is formed on the groove of ridge on the substrate to perform selective diffusion of impurity making the diffusion front reach the layer 4. In such a constitution, the current supplied for the layer 4 is concentrated in the active layer on the groove inside the laser distant from end to reduce the oscillating threshold value. On the other hand, the region near end subject to reverse bias status of P-N junction cannot be supplied with current. Resultantly the heating due to no light emitting transition as a cause of end-deterioration may be prevented from happening.

IPC: G06F12/08
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To obtain a cache coherence protocol which uses a tagged coherence state to increase the memory band width without immediately writing back a change value to a system memory. SOLUTION: When a tagged state is assigned to a cache line which is loaded with the change value latest, the history state related to the tagged state which is moved between caches (in the horizontal direction) can be used furthermore. This system is also applied to a multi-processor computer system having clustered processing units, and a tagged state is applied t one of cache lines in each group of caches which support different processing unit clusters. Priority levels are assigned to different cache states, and they include tagged states for response to requests which access corresponding memory blocks. Because of use of a crossbar, a tagged intermediary response is transferred to only selected caches which are affected by this intermediary response.

Abstract: PURPOSE:To prevent occurrence of the short ring of the telephone bell by increasing and decreasing gradually the current to the next code transmitter after the network control unit is actuated with the start signal sent from the central unit. CONSTITUTION:Terminal 51 of no-ringing network control unit 5 is connected to the telephone network, and terminal 58 is connected to the code transmitter each. With supply of the working power from terminal 51, all circuits 52-57 within unit 5 become active. And the start signal sent from the central unit is received at reception circuit 54, and then the necessary process is carried out through reception decision circuit 56. After this, switch circuit 57 is controlled to give switching to both terminal 58 and no-ringing connection circuit 55. Circuit 55 gives the slow connection between the rise and the fall of the power consumption level of the code unit. In such way, the occurrence can be prevented for the short ring phenomenon of the bell circuit caused by the sudden current change when the code unit is connected.
