IPC: B21C47/02
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To efficiently coil a oil free from a coiling deviation by making a ratio between the wedge quantity of a band like body and the crown quantity in which the points at a specified distance from the plate width both end parts of the band like body to a center side are made to the start points, larger than a prescribed quantity beforehand without requiring the modification of equipment in a large scale. SOLUTION: In the case of coiling a band like body e.g. a steel strip to be provided for rolling, a smooth profile is provided to a cross sectional shape of the steel strip beforehand. In the profile of the whole plate width 16, the plate width 1/10 positions 14 which is located from the plate width both ends to the plate width center part 15 side by the width 1/10 length 13, are made to the start points and the ratio C/W between the wedge quantity W12 and a crown quantity C11 is made larger than a prescribed quantity beforehand e.g. about to C/W>1. By coiling the steel strip having this positive crown, the centering force of the crown exceeds the coiling deviation force of the wedge to prevent the coiling deviation. The profile is easily shape-controlled in hot rolling to be formed.

Title: Alarm detecting system for optical receiver
Inventor: OGURA YOICHI
IPC: H04B17/00
Filed: 1986-07-22
Abstract: PURPOSE:To easily and exactly detect whether an optical signal is received or not regardless an error rate, by deciding directly the reception level of the optical signal. CONSTITUTION:A reception signal AS is obtained at an arbitrary time slot, and when it is decided that the level of a bipolar reception signal BS is lower than a threshold value Vth generated from a threshold value voltage generation circuit 20 by a comparator 21, a pulse signal FS outputted from a one-shot multivibrator 23 goes to an 'H' level continuously, As a result, an alarm signal IS of the.,H,. level which represents the reception of an optical burst signal is generated from a D flip-flop 24. Meanwhile, since no comparison output('M' level) CS is outputted from a comparator 21 when no reception signal of a constant level or more arrives, the alarm signal IS of an '' level which represents that no optical burst signal arrives from the D flip-flop 24, is generated. In this way, by setting the threshold value Vth corresponding to the identifying processing capability of a reception data, it is possible to surely detect the presence/absence of the reception signal with simplified constitution.

Title: Refrigerator
Inventor: IWAMOTO TETSUMASA
IPC: F25D23/06
Filed: 1989-07-03
Abstract: PURPOSE:To increase a cooling capacity by a simple construction and prevent frozen food from being melted by partitioning a duct into one for cooled air return and one for cooled air introduction with a partition wall and forming an opening of said cooled air return duct on the side of a refrigeration chamber on the side wall of said refrigeration chamber. CONSTITUTION:The air cooled with a cooling fan 15 and a vaporizer 14 cools a refrigeration chamber 10. The cooled air is partially introduced into a cover 19, a duct 28, an air intake section 29, responding with the temperature of a cold storage chamber 11 with a damper 17. The introduced air, after its temperature rises in the cold storage chamber 11, returns to the refrigeration chamber 10 by way of the opening of a cooled air return duct 30 and an opening 32 installed on the side of the refrigeration chamber 10, thus forming a cooling cycle. The cooled air introduced into the cold storage chamber 11 is heated with the return cooled air from the cold storage chamber 11 by way of a partition wall 31, which prevents the temperature in the cold storage chamber from dropping suddenly. Since the cooled air returning to the refrigeration chamber 10 is cooled reversely, the rise in the temperature in the refrigeration chamber can be minimized as well.

Title: Manufacture for semiconductor device
Inventor: KANEKO SEIJI
IPC: H01L21/84
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To provide a manufacture for semiconductor devices which decreases the number of photolithography step for isolating elements in an SOI structure part and a bulk substrate part, and can obtain finally an equivalent device characteristic, in the manufacture for semiconductor devices using a partial SOI substrate. SOLUTION: Since element isolating film thicknesses in an SOI structure part and a bulk substrate part are each a different film thickness, first, an element isolating photolithography and etching are performed in both the SOI structure part and the bulk substrate part, and an element isolating oxidation is carried out at a desirable element isolating film thickness in the SOI structure. Furthermore, after a nitride film is deposited, a photolithography step is performed so as to cover other than the bulk substrate with photoresist, and the nitride film of the bulk substrate is etched, and also well injection is carried out in the bulk substrate. After the resist is removed, an additional element isolating oxidation is carried out only in the bulk substrate part.  Thus, it becomes each possible to form the desirable element isolating film thickness and wells in the SOI structure and the bulk substrate without increasing the number of step.

The output voltage is the axle weight of the passing vehicle and detected through electrodes 22a and 22b. All the axle weights are added at the fall down of the passing signals, which are detected by a vehicle separator. The total weight of the passing vehicle is measured in this way.
