IPC: H01R25/00
Filed: 1989-02-23
Abstract: PURPOSE:To make it possible to load and unload an external enclosure in one easy step so that a projection of a fixing spring interlocks with a recession of the external enclosure elastically by crowning the internal enclosure with the external enclosure. CONSTITUTION:A projection 25 of a fixing spring 3 interlocks elastically with a recession 32 of an external enclosure 32 by crowing an internal enclosure 2 with the external enclosure 4. Accordingly, the external enclosure 4 can be fixed to the internal enclosure 2 without levitating the external enclosure 4, and the fixing spring 3 can be covered with the external enclosure 4. When a jig 28 is inserted into a jig insertion section 29 to punch a releasing push section 26 of the fixing spring 3, the external enclosure 4 can be released because the projection 25 comes off the recession 32. According to the constitution, loading and unloading of the external enclosure 4 can be made with one easy step.

Title: Method and apparatus for ink-jet recording
Inventor: SATO HITOSHI
IPC: H04N1/23
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To ease exudation of ink in an ink-jet recording system. SOLUTION: A correction table and an error table are installed. In the correction table, a count of discharge ink dots designated for each color in a unit area is preliminarily set in a correspondence with a combination of the counts, which is limited so that a sum of the counts does not exceed a preliminarily set upper limit. In the error table, an error brought about when the limited count of discharge ink dots of each color is set is preliminarily set correspondingly to the combination of the designated counts of discharge ink dots for each color in the unit area. At the time of printing, a count of discharge ink dots for each color after corrected is determined for each unit area from the correction table correspondingly to the combination of the counts of discharge ink dots designated for each head on the basis of binary image data.  At this time, errors of the error table are accumulated for every unit area, and an integral part when appearing in the accumulated value is reflected to the count of discharge ink dots and moreover the accumulated error is renewed.

Title: Simple container for food
Inventor: SHIBATA ISEO
IPC: B65D1/24
Filed: 1995-03-03
Abstract: PURPOSE: To enhance feed efficiency and durability by making the height of an edge frame less than the content housing height of an inner container and positioning the rear surface of the edge frame above the bottom surface of the inner container without reducing the amt. of content and damaging the appearance as a container. CONSTITUTION: In a simple container wherein the rear surface of the outer edge part 4 outward protruding from the upper edge of an inner container 1 is welded to and integrated with the upper end surface of an edge frame 3, the height (h) of the edge frame 3 is made less than the depth (d) of the container formed by the inner container 1. Therefore, if the edge frame 3 is fixed to the inner container 1, the shape retaining force of the container itself is obtained. Since a lid material 6 is engaged with the projection provided to the upper part of the corner part of a stepped part 5, the vol. of the container can be increased by making the height of the partition 2 formed to the inner container 1 larger than that of the outer edge part 4 of the inner container 1.  Many containers are fed in a stacked state because the height of the edge frame 3 is low and stacked at a vol. part with definite height.

Title: Data packet transmission system
Inventor: SHIMIZU TOSHIMITSU
IPC: H04L12/28
Filed: 1989-02-28
Abstract: PURPOSE:To secure data reception confirmation in data packet transmission and to preclude malfunction by adding a bit for requesting a terminal side to send the reception confirmation during polling for soliciting for the reception confirmation when the terminal side performs the reception confirmation every time one block is received. CONSTITUTION:When the system confirms the reception of an outgoing block by the terminal, the ACK bit is added in the transmission solicitation (P#l) to the terminal, i.e., a polling part. Namely, the system side adds the ACK bit in the P#l again unless the system side receives block ACK for a last block to request the terminal to resend the reception confirmation, i.e., 'Send the block ACK again because the block ACK is not received.'. Consequently, the data reception confirmation in the data packet transmission can be secured to preclude malfunction.

Title: Frequency stabilizer for semiconductor laser
Inventor: OSHIMA SHIGERU
IPC: H01S5/0687
Filed: 1992-03-03
Abstract: PURPOSE:To provide a semiconductor laser frequency stabilizer for stabilizing a control loop by using a filter for eliminating signals at specific frequencies before they enter the semiconductor laser. CONSTITUTION:A semiconductor laser 1 receives a signal at frequencies lower than 1/(2pt), where (t) is the response time of a control loop. Therefore, the output signal from a photodetector 11 contains signal components at frequencies around the frequency (f) of an a.c. signal generator 16, and signal components at frequencies lower than 1/(2pt) caused by output variations from the semiconductor laser. A high-pass filter 30 is provided to cut the signal components at frequencies lower than 1/(2pt) before they enter an amplifier 20. This compensates for variations in output level due to changes in injected current and thus eliminates unstable factors involved in the control loop.

Title: Production of foamed ceramic
Inventor: KAWAI HIDEJI
IPC: C04B38/02
Filed: 1995-03-06
Abstract: PURPOSE: To improve the dimensional stability of the products by reducing the change in dimensions on firing of ceramic foam. CONSTITUTION: A plurality of raw material powders different in refractoriness are granulated, respectively, the granules are dry-mixed, molded and the molded products are fired. The high-refractoriness raw materials include a foaming agent, while the low-refractoriness raw materials do not include where the difference in vitrification temperature is set to 200-400 deg.C between these raw materials. Thus, the low-refractoriness phase melts and the high-refractoriness phase is shrinking, while the latter phase is foaming. Since the expansion of the low-refractoriness phase is accompanied with shrinkage of the high- refractoriness phase, the change in dimension is reduced as a whole, resulting in increase of the dimensional stability.  The fluctuation in dimensions is reduced, the dimensional stability of the products is largely improved and the products of a desired bulk specific gravity can be readily and surely obtained.
